Tactile sensor - Smart, individual, simple, extravagant, futuristic - touch sensors, also known as KNX buttons, like to attract admiring glances and their modern design alone suggests to every user that this is more than a conventional light switch. Rockers, glowing LEDs, small symbols or even LCD displays give an idea of the numerous functions hidden behind many an installation. In addition, there is often a very noble selection of materials such as high-quality metal, acrylic or glass, which always exudes a touch of extravagance. But why are multifunctional touch sensors needed and how do you use their potential optimally? We give you a brief insight here.The basics in a nutshellTouch sensors are multifunctional control elements for the smart home.The design and function selection is huge, from a single button to a control center with 12 or more buttons, everything is possible.You can use it to control, for example, the light, its dimming, blinds, heating, entertainment center, door opener and all other devices in your home network.The button functions can be assigned individually and can be easily reprogrammed if necessary.Integrated LEDs or other displays often show the respective operating status or provide information about errors.   What is a touch sensor or a KNX button?You can operate the end devices integrated in your smart home network with a touch sensor or a KNX button. This can be blinds that you can raise and lower - light that you dim - the heating that you regulate or completely individual, user-defined scenarios. Depending on the model, operation is optically individual. In general, it is operated using a different number of buttons or rocker switches and/or even displays.The different types of KNX buttonsUsing a KNX universal button interface, you can basically turn any conventional button into a KNX button. These interfaces are installed in a deep device box behind the standard button and thus take on the task of the binary input, which converts the classic switching processes into KNX signals.Which doses are suitable?To do this, use a branch switch box with 4 screw domes or a deep switch box or an electronics box. Use our eibabo® search to quickly find the right item.This solution is particularly suitable for the standard application 'basic lighting' per room (see: 'What are standard applications?') or for the modernization of existing installations as well as for inexpensive and functionally manageable system extensions.'Real' KNX tactile sensors are much more complex and range up to control elements with elegant touch displays. Temperature sensors, LED displays and background lighting are often already combined in one device. In contrast to the simple interface variant, there is often the option of providing each key with additional functions, which are then triggered, for example, by a long press, double-click or even triple-click. TIP:We recommend planning well in advance so that you can later fit all the functions you need into your keypad. While some KNX push-button sensors require a separate bus coupler to which they are plugged, the bus coupler is already integrated in others. The eibabo® technology store also has both complete KNX pushbuttons and pushbutton sensor modules. The latter is 'only' about the technology and you can choose a matching design cover yourself. The possibilities are diverse - you can choose exactly what suits your project.The advantages and disadvantages of tactile sensorsThe central control of a large number of actions on different end devices is certainly the greatest advantage. The plus in comfort is combined with the flexible options for changing and expanding a well-planned setup. The disadvantage is certainly the slightly higher acquisition costs of a smart home solution compared to a conventional electrical installation. In the case of units with many keys and each assignment with different control variables (print, double-click), the overview of all the functions and their control can easily be lost.Unusual application examples in everyday lifeWe have already mentioned a few classic use cases. In the course of our more than 25 years of work, we have also been able to implement 'very special' projects. It starts with the smart opening and locking of the cat flap in the basement, continues with the choreographed lighting of exterior facades and doesn't end with the automatic pool cover, the fully automated aquarium or the heated driveway in winter.  You want to know more? We answer frequently asked questions.Nobody knows everything and sometimes there are small ambiguities that prevent us from correctly grasping connections or from deciding on one or the other product. You may also find an answer to your question in the following topics.How are the KNX devices programmed?Many interested parties are quickly startled by the term 'programming', but it's not that difficult at all, because it's not actually programmed with the 'ETS', but assignments and parameterizations are carried out.What does ETS mean for KNX?The term ETS (Engineering Tool Software) means that it is programming software for commissioning the KNX devices. The tool is more of a software for parameterization and basically also suitable for laypersons with an interest in the logic of the KNX.No programming knowledge or programming language is required. If you are interested in the rather simple logical connections of the KNX bus, you are in a position to create a project. Of course, more complex projects require a certain amount of experience. We always recommend having the basic project created by an experienced system integrator. This allows you to easily change important parameters yourself later on, since many things change in the life cycle.Which touch sensor or KNX button should I buy?Well, we can't give a general answer to this question, but we can perhaps provide some impetus for decision-making. KNX push button sensors are available in a variety of designs. The manufacturers offer solutions for every taste. However, you should not only be guided by the optics. In addition to the optics, eibabo® also recommends checking the applications (parameters and functions) provided by the manufacturer for the ETS (Engineering Tool Software). Significant deficits can open up here in the course of a project if the beautiful button were not able to control the necessary actions correctly. Plan exactly which requirements you place on the respective push button sensor and then select a suitable model accordingly. NOTE:ETS is standardized software for commissioning the KNX devices and can be obtained from www.knx.org. With regard to the design, you should also rely on optics that have a positive effect in the long term and not follow every short-term trend, only to realize a few years later that the brightly colored displays and the LEDs for various status messages on the buttons in the wall were a bit too much of a good thing. It makes sense to ensure that displays can be dimmed or configured in different brightness levels and status LEDs can be configured and switched off. A timeless surface design, for example, has simple elegance, looks classy, is durable and has no playful rockers that could quickly gather dust.How do I recognize whether a touch sensor already has a bus connection?Some touch sensors already have a bus connection. If you're not sure, a look at the back will clarify.Image: KNX push button sensor - Jung 4047TSMA touch sensor is equipped with a bus coupling if it has a black and red (or gray and red) terminal for the bus on its back. This 4-wire terminal with plug-in terminal connection serves as a distributor for up to four KNX lines.How do I keep track of the individual functions of complex touch sensors?We would like to encourage you to think: Imagine you come into a room and have to press the small second rocker from the top left on an 8-way pushbutton sensor every day to switch on the basic lighting. It can quickly happen that you accidentally set the pressure point on the adjacent rocker and unfortunately operate the blinds at 11:00 p.m. Not to mention how a guest or child is supposed to cope with it.So it can indeed be a bit difficult to always steer correctly. But: The advantages of the KNX lie in the intelligence of the system, which is implemented by the system integrator based on their experience and your functional requirements. For this reason, you should arrange functions logically or thematically and, if necessary, group them on easy-to-use buttons. If necessary, it is advisable to divide standard applications and detailed circuits into different buttons at different mounting heights.What are default applications? What is the best way to implement this into the system?The first switch box is usually placed on the 1.05m upper edge of the finished floor. At this point you should mount a conventional double button and connect it twice to the bus via a very inexpensive KNX button interface. Of course, you can also mount 2 or 3 double buttons and integrate a 4-way or 6-way KNX button interface. A deep switch box or electronics box is installed as a flush-mounted box in order to be able to place the small button interface behind the double button.Here you save!Combine a KNX button interface with a conventional double button.With the conventional double button, you have more choice in the design of the switch range and, in the event of defects or design changes, you can obtain a lifetime replacement without having to reprogram. You can assign the most important and most frequently used basic lighting to this button or parameterize the button or the button interface with light scene recall. A beautiful flat switch is also very easy to use for guests and children.What is meant by detailed switching on the KNX button?You should mount detailed circuits of the certainly many functions in a room on the 1.60m upper edge of the finished floor and call them up from a room controller or multiple push-button sensor with an optionally integrated room temperature controller (see also our multiple control unit catalogue). A room temperature controller already requires this mounting height for optimal control. At this user-friendly height, you can then carry out all additional controls for additional lighting, blinds, roller shutters, entertainment, etc.Touch sensors wear out very quickly! Is that correct?Like all other technical components that are used more or less every day, tactile sensors and control points in general are subject to a certain amount of wear and tear. However, this is no different than with conventional buttons or switches. It is possible that individual parts that have been in use for a decade are then worn out.Does it make sense to control the heating using touch sensors?Definitely, as a rule, individual room heating controls are also required for KNX installations. In terms of value for money, the combined buttons with room temperature controllers are the best choice, also in terms of user-friendliness.Which manufacturer offers the most beautiful and best KNX buttons?Beauty is in the eye of the beholder, we won't take a position on that. In terms of quality, however, all brands perform very well. There is no such thing as the 'best' touch sensor. Each manufacturer has its individual strengths in terms of applications (parameters and functions). eibabo® offers switches from all brand manufacturers (from ABB, Berker, Busch-Jaeger, Gira, Hager, Jung, MDT, Merten to Siemens).

Surge protector - measur./control - Modern sensors, measuring devices and probes monitor and control complex and interdependent processes. Protect these operations from power surge failures. We will introduce you to different MSR surge arresters and support you in your purchase decision.   Automated processes intervene deeply in a building management system or in production processes. As a result, a very high degree of availability of the determined and transmitted measurement data and control signals is required. Surge protection devices make a significant contribution to safeguarding the function of this technology in the event of voltage peaks of all kinds. Depending on the risk potential and the level of protection required, select the surge protection devices that are right for you and combine them with other protective circuits if necessary. Image: Dehn DPA-M-CLE-RJ45B-48 surge arrester What are MSR surge arresters? MSR stands for measurement technology, control technology and regulation technology. MSR technology is used in particular within modern bus systems and telecommunications systems. Private and industrial areas of application are: air conditioning and refrigeration systems heating systems and ventilation systems the field of water technology and waste water technology the electronics sector and smart home   The MSR overvoltage protection devices are used in electrical engineering to limit and divert overvoltages in electrical lines. Particularly sensitive measuring devices and control devices can be damaged by overvoltages, incorrect measurement data can be determined and incorrect control signals can be sent. But how does the overvoltage come about? Lightning strikes, short circuits, electrostatic discharges or switching operations by the network operator generate mains voltages which are well above the normal value of 230V in Germany. The consequences of such an event depend on the level and duration of the overvoltage and the speed of the voltage pulse.   The MSR surge arresters (Surge Protective Devices SPD) are usually installed directly in front of the signal inputs of the measuring devices and control devices to be protected. In the context of a three-stage overvoltage protection, these represent the so-called fine protection (type 3). What is measurement technology, control technology and regulation technology? MSR technology records a wide variety of situations and states within automated processes. Depending on the type and area of application, individual parameters are determined using different measurement methods. Typical measured variables are temperature, pressure, speed, humidity or chemical composition. These measured variables are converted into electrical signals such as current, voltage or resistance and serve as the basis for triggering logical actions. How is an MSR surge protection constructed? A general overvoltage protection is usually structured in three stages and is part of the internal lightning protection of a building. There are different requirement classes for overvoltage protection devices. We distinguish between type 1 (rough protection), type 2 (medium protection) or type 3 (fine protection). When selecting suitable protective devices, the type of possible fault and the type of device to be protected are considered. This results in a combination of different surge arresters adapted to the respective needs, which together ensure coarse, medium and fine protection.   Type 1 coarse protection devices are used to divert high lightning currents. These reduce the residual voltage of an overvoltage to a level between 6000 volts and 1300 volts. Type 1 devices are usually switched before the house installation. This means that the high lightning current cannot even reach the house distribution system.   Type 2 devices provide medium protection. They reduce the residual lightning voltage to values between 2000 volts and 600 volts. They are installed, for example, in the sub-distributors of individual apartments or parts of buildings. Medium protection devices also limit dangerous transient overvoltages. These are caused by the switching of transformers, circuit breakers, motors or inductive loads. Already knew? Surge arresters are not disposable fuses. The devices can ensure reliable protection over a long period of time and do not need to be replaced after they have been triggered.   The Type 3 overvoltage protection further reduces the remaining overvoltage. These devices provide fine protection and protect against voltages up to a level of 1000 volts AC or 1500 volts DC. The MSR surge arresters available in this eibabo® catalog belong to this category. Are MSR Surge Arresters Really Necessary? Whether special protective measures against overvoltage are required for your MSR devices must be considered individually for each installation. Estimate the risk objectively, taking into account the probability of overvoltages and overcurrents. Base this assessment on all existing parts of your protective measures against overvoltages. Include the risk of electromagnetic phenomena such as lightning discharges or earth potential rises in your considerations. Ultimately, you should achieve reliable protection for your entire system. Please consider the organizational and financial consequences that the failure of important measurement and control devices would have for your operational processes. When should I choose an MSR surge arrester? Power connections and data lines are an integral part of our everyday lives. Stable signal transmissions are essential for smooth business operations, and not just in industrial or commercial environments. Our high-tech lifestyle also demands reliable connectivity. If you recognize yourself in any of the following questions and answers, then MSR surge arresters are for you.   Do you value security? Security devices such as alarm systems, door intercom systems, access controls and emergency call devices only offer complete protection if the power supply, the monitoring sensors and the data lines work permanently. MSR surge arresters protect those systems that ensure your protection.   You don't want to do without the amenities of modern living comfort? A lot of planning, work and money goes into modern smart home installations. The automatic control of temperatures, shutters or multimedia applications enable a comfortable living environment. With MSR surge arresters, this convenience is maintained even in the event of an overvoltage.   TIP:Investing in reliable surge protection is usually less expensive than replacing, repairing, and installing new equipment.   Would you like to secure your independence? The production of your own electricity is becoming more important every year. Modern and environmentally friendly mobility solutions and heating systems rely on electricity from your own photovoltaic system. The efficient use and storage of electricity requires complex control devices. With an MSR surge arrester, you can protect this expensive technology from surge damage. You retain your independence from energy suppliers.   Do you want to protect investments and preserve property? Real estate is an investment and provision in one. The technical equipment of a building has a significant influence on its value. By using MSR surge arresters, you not only get the building services, but also your old-age provision.   In our catalog you will always find the right surge arrester tailored to your requirements for your individual device variants. You get the best quality at low prices.

Blind actuator - How can I automate my shutters and blinds? Can the time of day, the weather and the position of the sun be taken into account? We provide recommendations and information on the purchase of KNX blind actuators and show you what options the technology offers you in everyday life.If you want to build a new house or renovate an existing building, many questions arise. The technical equipment in particular must be well thought out, because a later change is then only possible with a lot of effort. If you already include the advantages of intelligent building automation in your planning, then the opening, closing and shading of the windows will also play an important role.Useful application examples for controlling blinds or roller shutters:the up and down of roller shutters and blinds according to time specificationsturning the slats of blinds based on the brightness in the roomthe automatic opening of roller shutters or blinds when windows are openedthe simultaneous operation of several shading systemsthe flexible control or regulation of the roller shutters when you are absent via a smartphone appthe automatic drive to the safety position in the event of a storm alarm and back after the all-clearthe blocking of operation for certain peopleautomatic shading according to geographic location and position of the sun (astro control) The use of modern KNX blind actuators supports you in realizing all these projects. They ensure more security, greater comfort and increase the value of your property.  What distinguishes a KNX blind actuator from a KNX switching actuator?All motorized equipment such as blinds or roller shutters can be automated using KNX blind actuators. Standard 230V blind actuators therefore have 2 channels per switching output. A channel to drive up and a channel to drive down. The channels are mutually locked to prevent damage to the drive. So only one phase can be switched through to the drive at a time, never both at the same time. TIP:Never use KNX switching actuators to control blinds and shutters without a downstream isolating relay. With classic KNX switching actuators, the channels are not mutually locked. It would therefore be possible to connect more than one phase to the drive. This can quickly lead to damage to the technology. There are models which, depending on the configuration, can be used both as a switching actuator and as a shutter actuator. Please read the specification of the respective actuator.What should be considered during installation?Motorized 3-point drives must not be connected in parallel. Group formations may only be carried out using isolating relays or group control devices if the manufacturer does not provide for any isolating function. For example, for 4 windows, each with a drive, you should use a KNX blind actuator with 4 channels. There is also the option of operating several drives via one channel using conventional isolating relays. The shutter actuator channel then controls the isolating relay and the drives are connected to the isolating relay. In the meantime, however, the prices for the KNX actuators have fallen massively, so that there is hardly any need to reduce costs by using isolating relays. TIP:When selecting your components, always prefer one blind actuator channel per blind motor. For example, if you would like to integrate 6, 8 or 12 blinds into your system, you will find the appropriate actuator here in the shop.Are blind actuators with 230V AC better than models with 24V DC?This question is not about better or worse. Rather, the type of voltage of the drives should always be considered. The drives of blinds or roller shutters are often designed as 230V AC (alternating voltage) or 24V DC (direct current). That's why you have to buy the matching blind actuator or roller shutter actuator. A 24V DC blind actuator or roller shutter actuator has a plus and a minus connection. A suitable KNX actuator generates the direction of travel (up/down) by changing the poles (pole reversal).Do shutter actuators require a separate power supply?The 24V DC mains supply is not provided by the actuator and must also be installed externally depending on the power requirement for simultaneity (central commands). In this case, very large power supply units can become necessary, which, in addition to high costs, also require a large amount of space. If you can, order 230V AC drives and matching 230V KNX blind actuators from the supplier. These also require their own power supply, but no additional power supply units.That is the reasonSo-called monostable relays are installed in the shutter actuators, which are open and not active when idle. However, the relays continuously require energy as long as they are closed (e.g. for the duration of a blind movement). The bus voltage alone cannot cover this requirement.In contrast, there are bistable relays in classic switching actuators. These only require some energy in the brief moment of switching from one position to another. This can be implemented via the bus and an additional power supply is usually not necessary.What do I need an SMI KNX blind actuator for?SMI stands for 'Standard Motor Interface' and is an intelligent, uniform and manufacturer-independent interface in building automation. This is used to connect various operating resources, such as window drives, roller shutter drives or blind drives to a higher-level building management system. There are SMI KNX blind actuators for drives with an SMI interface. These intelligent drives are therefore able to exchange data telegrams across manufacturers.Which actuators are recommended for controlling roller shutters and blinds?eibabo® carries KNX blind actuators, KNX roller shutter actuators and KNX SMI actuators from ABB, Berker, Busch-Jaeger, Gira, Hager, Issendorf, Jung, Lingg & Janke, MDT, Merten, Siemens, Somfy, Theben, Warema and many other manufacturers.Over 25 years of experienceAll actuators that you get here in the shop are of high quality and reliable. We regularly use these actuators in our projects all over the world.Benefit from our low prices and take advantage of safe, fast and worldwide shipping.1-byte communication object - what is that?In any case, make sure that your blind actuator or roller shutter actuator has a 1-byte communication object for the runtime and slat, in order to be able to enable automatic or targeted control if required.There are no slats in roller shutters, which is why roller shutter actuators do not have the slat communication object, only Up/Down/Stop. Roller shutter actuators often have a 1-bit object for a defined positioning movement that can be set via the ETS software.1 byte means that values between 0-255 can be approached, which correspond to 0-100% related to the travel time. The parameters often allow the running time to be set according to the driving time. The travel time of the blind or roller shutter is entered once in the actuator using the ETS software, namely for a complete opening or closing for each channel of the actuator. There are also actuators for evaluating limit switches, which the motorized drive provides.Image: KNX blind actuator ? Eibmarkt JA.6.230The extensive application of the KNX blind actuator / roller shutter actuator JA.6.230 from Eibmarkt® shown here enables a wide range of parameterization via the communication object, including scenes for runtime and slats, blocking functions, automatic functions, security functions and alarm functions, movement limitations, position feedback and much more.Can a layperson use the ETS software to program the KNX devices?Don't be put off by the term 'programming'. The ETS software is only used to assign and parameterize certain actions. Programming skills or learning a programming language are not required. If you have some imagination to understand logical connections, then you are quite capable of creating a project.our recommendationFor more complex projects, a certain amount of experience is of course helpful. Have the basic project created by a qualified system integrator. In this way, you will later be able to easily change important parameters yourself if circumstances require it.Roughly explained: Imagine the folder system on your Windows PC or iOS computer. Here you create your own structure, save files in it and create links to other folders. This is similar with the ETS software. The 'folders' can be floors or rooms and the 'files' in them are the sensors or actuators of the respective room or electrical distribution cabinet, which you then link to one another.What types of installation are there for KNX blind actuators?KNX blind actuators are available for every type of installation at eibabo®. For example, for installation in the electrical distribution, then these carry the suffix 'REG' for series installation devices or as a flush-mounted version 'UP' for installation in a mounting box or junction box or as a built-in version 'EB' for integration in ducts or similar. However, additional protection must also be taken into account for built-in versions depending on the installation.  Catalogue content:In this eibabo® catalogue Installation bus systems > Shutting actuator for bus system you will find items from the following product groups:Item overview:Azimuth controlBinary inputBlind functionBuilding controlBuilding system technologyCable entryCombination actuatorControl moduleControl unitsDIN railDIN railsDrive controlEngine control unitEngine controllerHome controlInput moduleLight domeNormally open outputOutdoor areaOutput moduleRadio receiverSeries installationShutter controlShutter outputShutter switchSplash proofSun protectionVentilation flapfrom the following manufacturers:Manufacturer overview catalogue Blind actuator:ABBBerkerBusch JaegerEatonEIBMARKTElsoEltakoESYLUXFinderGiraHagerJungLingg & JankeMDTMertenPehaSchneider ElectricSiemensSomfyThebenWaremaWieland
Modular plug connectors - What are modular connectors? Where can I use these in my home, commercial or industrial installation? What are the benefits of modular connectors? Does the eibabo® shop offer inexpensive and individual connectors? We answer these questions in the following post. In the field of electrical installation, connectors are of particular importance. Using plug-in connections, it is possible to connect two identical or different cables or lines with one another in a form-fitting manner. Such connections can also be released again.Modular connectors are constructed in such a way that they have properties in common with other components. These are, for example, the same installation dimensions or the type of connections and attachments. These work individually, but can also be combined with others within an assembly unit to form a larger whole or exchanged for one another. If you are interested in a flexible and modular structure for your electrical installation, browse through this eibabo® catalogue. Select the modular connectors that are right for you.Why are there modular connectors?The modern, modular connectors go back to the development of the American telephone system. The phone companies dominated the phone network for the first few decades and didn't allow third-party devices. This applied to both commercial and private use. To connect buildings and individual telephones to the network, bulky plugs were used, which had been in use since the 1930s. These had to be installed and maintained by specialist companies at great expense.As the telephone system became more widespread, a way was sought to reduce the high service costs. These efforts resulted in a modular system of components for standard connections. These were smaller, cheaper and easier to install. As a result, a standard was established for the connection between the telephone company's equipment and the customer's equipment. These standard interfaces were known as Registered Jacks (RJ). The RJ interface specification includes:the physical construction of the plugthe wiring patternsthe signal specifications Registered jacks are identified by the letters RJ. Additional digits describe the type and its properties. Modular connectors and RJ connectors are common names for the same devices. The use of modular connectors has helped fuel the global development of voice and data communications.Picture: Ruthenbeck UM-Cat.6A iso A universal moduleHow are modular connectors constructed?Modular plugs consist of a plastic or metal housing. The housing encloses stamped metal contacts separated by insulating channels. The contacts in the plug match the contacts in the socket. Part of the housing can often be used to lock the plug-socket connection and serves as strain relief. A modular plug or socket is assembled into a cable using a crimping tool. Depending on the use, individual connectors can have an even number of two to ten contact points. For this reason, the widths of the two connecting bodies vary. Not all contacts have to be assigned a line. Telephone (RJ11) connectors typically use four to six ports. RJ45 Ethernet connections have eight ports. The specification details describe the wiring. For example, a 6P2C connector has six positions and two contacts. A four-position, four-contact connector is designated 4P4C. TIP:The specification given for the wiring does not define the purpose of the wires. Modular connectors are also referred to as male or female. The male connectors are plugs or headers, the female ones are sockets or sockets. Some modular connectors supply low voltage AC or DC power to small electronic devices.What are the advantages of modular connectors?The biggest advantage of modular connectors lies in their standard use in communication and data transmission. The connectors are also used in production, in field installation and in the maintenance and repair of machines and systems. The advantages in production are:low prices and constant availabilityAssembly of plugs and cables without solderingrobust versions available for industrial applicationsPossibility to use the sockets on boards by reflow soldering The same advantages apply to installation and repair. In addition, value is placed on the following properties:Simple cable assembly and replacement of old connections on sitequick assembly with simple toolsnumerous wiring options This avoids production downtime and increases the reliability of a system.Where are modular connectors used?The use of modular connectors allows you to individually configure contact connections. Reliability and ease of use have made modular connectors an easy solution for many applications. The most common applications are data networks, telecommunications and low-speed serial connections. Due to the efficient and compact designs, these are also used as alternatives for bulkier and more expensive connectors in various products. Modular connectors are used worldwide and are among the essential components in data transmission and communication. Modular plug connections are also used in the industrial sector. Standardized assembly units are available for machines and systems, into which a wide variety of plug connections can be integrated. This allows individually multifunctional plugs and sockets to be put together. Use compact plug connections in terminal boxes and control cabinets.What types of modular connectors are there?There are many different types of modular connectors. The world's best known and most widely used modular connectors are:RJ10 - (4 positions and 4 contacts) - connects a telephone handset to a receiverRJ11 - (6 positions and either 2 or 4 contacts) - is used to connect telephone lines and modems, with 4 contacts with power supply via the second pairRJ12 - (6 position and 6 contacts) - for telephone line and additional control lines, used in larger telephone systemsRJ13 - (6 position and 4 contacts, with a circuit behind the line) - for telephone line and additional control linesRJ14 - (6 positions and either 4 or 6 contacts) - is used to connect two telephone lines, with 6 contacts with power on the third pairRJ45 - (8 positions and either 8 or 10 contacts) - Connector for high-speed data transmission in computer networks What special properties do modular connectors have?Special requirements must be met when modular connectors are used in factories, in automated processes or in image processing systems. Many of the modular connectors therefore have additional features. This makes them usable for specific applications. For example:shieldingIf electromagnetic interference is to be expected or the lines are very long, shielded lines and plug connections are often used. These cancel out electromagnetic interference. keyingDue to an attached tab, insertion of a true RJ45 plug into a jack is only possible in one orientation. This is to avoid improper wiring. Standard 8P8C connectors do not have this security feature. AssemblyFor production use, panel mount, board mount, through-hole mount, and surface mount are often possible. The sockets can have a vertical or horizontal orientation. display functionsModern modular connectors may also contain LEDs of different colors to indicate connection status. magneticsMagnets must be taken into account with any Ethernet connection. These are part of the Ethernet specification for 10BASE-T and 100BASE-T networks. The integration of the magnetics in the RJ45 socket shields against electromagnetic interference. Data connections are becoming more reliable. Highest qualityModular connectors are used in systems where high reliability and performance are important. These are, for example, the military and aviation and space travel.In order to meet the highest requirements, high-performance shielding, special coding, protective sleeves and particularly robust parts are used in these so-called Hi-Rel (High Reliability) models.Which manufacturers produce high-quality modular connectors?Implement tailor-made solutions for your requirements or for the wishes of your customers with our modular connectors.

Bell transformer - The ringing, ringing or humming at the door, whether with a gong or a melody, keeps us in suspense. Who will be standing outside? In order for the doorbell to work reliably, correct installation is mandatory. Since the classic doorbells mostly work with voltages between 8 and 24 volts, you cannot connect them directly to the 230V voltage of the house. A bell transformer ensures a voltage reduction and prevents burnout as soon as current is applied via the bell button. Roughly speaking, such a transformer diverts excess current from one coil to another coil on the input side and thus ensures the correct voltage on the output side. You can find a large selection of high-quality bell transformers from various manufacturers here in the eibabo online shop. Your purchase in our store is protected by Trusted Shops buyer protection.Catalogue content:In this eibabo® catalogue Devices for distribution board-/surface mounting > Bell transformer you will find items from the following product groups:Item overview:Bell transformerBell transformer series installationBell transformersConverterDoor stationElectrical installation technologyMains transformerMET safety transformerModular installation deviceModular installation modulePower supplySafety transformerSingle-phase safety transformerStandard bell ringing transformerStandard bell transformerSystem devicesTransformerfrom the following manufacturers:Manufacturer overview catalogue Bell transformer:ABBBusch JaegerDoepkeEatonElcomGrotheHagerLegrand BticinoNovarSchneider ElectricSiemens
Distributor-timer - digital - Don't you also think that many electrical consumers don't have to be in operation all day? Would you like to save costs and conserve resources? This is possible with timers for the control cabinet. Find out here which functions digital distribution time switches can take on and which special features you should pay attention to when buying.At eibabo® you will find the right digital distributor time switch for installation in the electrical distribution board. We carry a large selection of Astro timers, weekly timers and yearly timers. Manufacturers of high-quality devices include Hager, Finder, ABL Sursum, Theben, ABB, Stotz S&J, Legrand (BT), Grässlin, Eltako and Schneider Electric. In the following text we will go into the individual variants in more detail.What are distribution timers?A time switch for the junction box is an electronic or mechanical device that switches electrical consumers on a time-controlled basis. These can be switched on and off without having to flip the switch yourself. This can be useful in private households as well as in commercial companies and in the industrial sector. The purposes of the distributor time switches include, among other things, the automatic switching on and off of lighting systems or the control of fixed house installations such as heating, ventilation, lawn sprinklers and air conditioning units. This not only saves you time, but also money.NoticeDistribution time switches are often offered in grid dimensions (pitch units). Depending on the equipment, such a device requires one to four modular widths in the control cabinet.The advantages of a timer are therefore obvious: electricity costs can be reduced effectively through the targeted control of your electrical devices. At the same time, you have the option of making your home less attractive to burglars, for example by simulating your presence using optionally available random functions.You can also get digital or analogue timers for the socket in another catalog from the eibabo® shop. Their function is comparable to that of the distributor time switches. However, the area of application extends to 'mobile' devices that are not permanently installed. These include Christmas lights, aquarium technology or decorative items such as fountains.What functions do distribution timers offer?A high-quality distributor time switch offers numerous functions and programs for the individual setting of the switching cycles. These include:60 min program / 24 h programWeekly program / annual programAutomatic summer/winter time changeoverholiday programimpulse programcycle programastro programrandom programPermanent switching ON/OFFexpiration timerhour meter Image: Theben TR 644 top2 RC distribution time switchWhat is the difference between each type of timer?We often come across terms such as astro timers, weekly timers or yearly timers. With regard to a purchase decision, the question then arises as to whether there are significant differences between these models. The basic function is the same for all models. The differences lie in the detail and the setting options of the individual variants. The astro function of a timer adjusts the switching times daily to the seasonally changing length of the day. In other words: When the days get longer in spring, the device switches on a little later every evening and a little earlier every morning. This process is calculated electronically and does not require a brightness sensor, for example, which would otherwise have to give the command to switch the light on or off. With a weekly timer, you can set individual switching times for each day of the week. In contrast, the function of a very simple time switch is limited to setting switching cycles within 24 hours.Already knew?Modern timers have a powerful power reserve. In the event of a power failure, this ensures the function of the timer for up to 10 more years.The annual time switch offers even more extensive functions. This means that different switching times can be provided for each calendar day and vacations and public holidays can be taken into account.Do distribution timers require a separate power supply?Digital timers always require energy to operate. As a rule, a distribution time switch is clamped onto the DIN rail of the control cabinet and supplied with mains voltage via an integrated power pack. Time switches that are exclusively battery operated are rare. These are typically analogue variants, which are used, for example, as 'door openers' in stables when there is no electricity.Is a digital timer always better than an analogue model?An analog timer works mechanically, a digital timer works electronically. Whether one or the other variant is more suitable for you depends on your requirements for the device. Mechanical timers usually have a higher-level switch with which you can switch the device off completely, switch it on permanently or switch it to switching mode. Switch buttons arranged in a circle represent the daily routine. There are usually 48 buttons and each button stands for half an hour. Activate or deactivate the corresponding switching period by pressing or pulling out. Compared to analog timers, digital timers offer significantly more setting options and functions. In contrast to mechanical timers, you can usually set several switching programs down to the minute over days or weeks. The distribution timer is operated using buttons and a display. TIP:If you want to control more than one device with the distribution timer, choose a model with the appropriate number of channels. This saves a lot of space in the control cabinet. Times and switching programs are clearly shown on the display. In terms of accuracy and functionality, a digital time switch is clearly superior to the analogue version. However, it requires a certain learning phase to understand the technology and set switching programs. If you only need 'rough' and daily recurring switching processes, analogue time switches are still a good alternative. These are set up and ready to use in just a few seconds.Can distributor time switches be programmed using an app or externally?There are distributor time switches that have Bluetooth and can be configured using an app. This allows you to display and change the switching states via smartphone or tablet computer. The prerequisite is the coupling between the input devices and timers within a network. Another way of programming the switching times is to use manufacturer-specific software. You can transfer the switching information to a special memory card via the USB interface of your computer. The memory card can then be connected to the time switch on the construction site/in the switch cabinet and the switching data can be loaded into the switch and vice versa.Doesn't a distribution timer consume more electricity than it saves?If the focus is on switching a consumer (e.g. the lighting) on and off, a distribution time switch is of course useful. As a rule, active end devices consume significantly more power than a timer. The question asked above relates to switching off a device that would otherwise run in standby mode for hours.To answer this question, a distinction must be made between an analogue and a digital time switch. An analogue model is less complex and usually has an output of less than 1 watt. With an electricity price of 40 cents per kilowatt hour, for example, the consumption costs are around 1 cent per day with 24 hours. With a digital timer, you have to assume around 2 watts and thus calculate electricity costs of 2 cents per day. In this calculation example, the investment costs for one or more time switches should also be taken into account.You can now compare this with the standby power consumption of your devices. This essentially depends on the type, age and number of devices. Old devices with displays consume more power in standby than modern electronics with only one control LED. A mix of new and old devices in the household currently results in an average consumption of 1 to 2 watts per device. If you need a separate timer for each electrical device, using them to save standby power is therefore not economical. The situation is somewhat different with distribution time switches, which can switch several devices or machines with a high standby current at the same time. This may save you on standby electricity costs, although this is not the primary reason for using a timer in these cases either. TIP:Pay attention to the shortest switching time of the device if you want to switch short intervals. Some devices only switch every minute and only a few devices switch every second or even faster. An example: If you have a terrarium with a sprinkler system, the nozzles should usually only spray for a few seconds. This is to maintain high humidity. Prolonged spraying may flood facility and animals.  Catalogue content:In this eibabo® catalogue Devices for distribution board- / surface mounting > Digital time switch for distribution board you will find items from the following product groups:Item overview:Astro timerBuilt-in timerDaily timerDigital timerDistribution timerEnergy efficientExpansion moduleInstallation timerJunction boxLighting controlLocation dependentPosition dataPower reserveProgram clockQuartz timerSeries installationTimerTimer moduleTimersUniversal timerWeekly programWeekly timerYear time switchfrom the following manufacturers:Manufacturer overview catalogue Distributor-timer - digital:ABBDoepkeEatonEltakoFinderHagerHamaLegrand BticinoSchneider ElectricSiemensTheben
Time relays - What are time relays used for? Sometimes it may be that your structural conditions make it necessary to delay electrical switching processes. Perhaps you still have to walk through a dark garage after activating the light switch, or a motion detector should only be activated after you have left a room. In these and many other scenarios, the use of a time relay can be useful. This ensures that a certain function is only activated or deactivated after a certain period of time. You can set the length of this period of time on the relay.What is a time relay?Timing relays or delay relays are simple control relays that control defined events based on time sequences. The difference between a classic relay and a timer relay is when their output contacts open and close. In a control relay, this occurs when voltage is applied and removed from the coil. With the time relay, the contacts can open or close before or after a certain delay. The installation usually takes place in the control cabinet on the DIN rail. TIPThe set time intervals can be set between milliseconds and hours depending on the relay. Typically, the delay is initiated or triggered by one of two methods:applying or switching off a control voltagethe occurrence of an impulse / trigger signal What functions do time relays perform?It is often difficult for the layperson to understand technical descriptions. When describing the functions of timing relays, we encounter terms such as control voltage, response delay, release delay, pulse shaping or make contact. In order to give you an understanding of how the time relays work, we describe the switching options below using simple examples.To make our examples easier to understand: Always assume that you only switch a 'control voltage' on or off using a switch or button in order to set a switching process (scenario) in motion. However, the actual circuit goes via the relay. Pressing a switch or button when using a switching relay does not necessarily lead to an immediately visible action. You only tell the relay that the preset scenario should now run and that it has to carry out the corresponding switching at the desired time. The following ten scenarios are most commonly implemented with time relays:Scenario 1 - The fallback delayThe release delay is also called switch-off delay.Example: When the control voltage is switched on using the switch (ON), the relay closes the circuit and the light lights up. If you press the switch again (OFF), the light stays on and the set delay time starts to run on the timer relay. The relay keeps the current flowing. At the end of the time period, the relay breaks the circuit, turns off the light and goes into sleep mode. When the light is switched on again using the switch (ON), the process starts again.Scenario 2 - The response delayThe response delay is also called switch-on delay.Example: When the light is switched on using a switch (ON), the time set on the relay starts to run immediately. Only after the time has elapsed does this close the circuit and the light lights up. Now when you press the switch again (OFF), the relay will directly break the circuit, turn off the light and go into sleep mode. When the light is switched on again using the switch (ON), this process starts again. Depending on the model, after the response delay has been interrupted, the time that has already elapsed remains stored or is deleted.Scenario 3 - The impulse controlled response delayThe switch-on delay is not triggered by a permanently applied control voltage, but by a pulse (briefly applied control voltage). These are also referred to as trigger signals.Example: In contrast to scenario 2, a short impulse in the control voltage is sufficient to set the scenario in motion. You don't turn on a switch, but press a button, for example. A preset time starts to run at the relay and then it closes the circuit for a previously defined period of time. Then it goes back to sleep mode. You can usually set both time periods individually. A classic application is a door opener. To do this, briefly press a button. After the set time (this can only be milliseconds), the relay interrupts the circuit on the electromagnet of the door lock for e.g. 3 seconds. During this time, the door is open and visitors can enter. After these 3 seconds have elapsed, the relay automatically restores the power supply to the electromagnet and the door is locked again.Scenario 4 - response delay and release delayThe circuits from scenarios 1 and 2 are combined with each other.Example: When the light is switched on using a switch (ON), a set time immediately begins to run on the relay. Only after this period of time has elapsed does this close the circuit and the light begins to shine. If the switch is then actuated again (OFF) and the control voltage is thus interrupted, a set delay time begins to run. The relay keeps the current flowing. Only after the time has elapsed does the relay interrupt the circuit, switch off the light and go into idle mode. Depending on the model, after the response delay has been interrupted, the time that has already elapsed remains stored or is deleted. Depending on the relay, the response delay and release delay are either of the same length or can be set independently of one another.Scenario 5 - The relay as a clock (starting with a pulse)You know this from the turn signal in the car. It is a flasher relay.Example: You press the switch (ON) and the relay closes the circuit immediately. The light glows. After a defined period of time, the relay interrupts the circuit and the light goes out. After another defined period of time, the relay closes the circuit again and the light shines again. This interval continues as long as the control voltage is present. Press the switch (OFF), interrupt the control voltage. The interval switching ends at the relay and it goes into the idle state.Image: Finder 83.02.0.240.0000 time relayScenario 6 - The relay as a clock (starting with a pause)This scenario is similar to scenario 5, it just starts with a pause, not an impulse.Example: You press the switch (ON) and the preset pause time starts to run on the relay. Only then does the relay close the circuit. The light glows. After a defined period of time, the relay interrupts the circuit and the light goes out. The break time begins again. Then the relay closes the circuit again and so on. This interval continues as long as the control voltage is present. Press the switch (OFF), interrupt the control voltage. At the relay, the interval switching ends immediately and it goes into idle mode.Scenario 7 - The fleeting switch-on relayExample: When the control voltage is switched on using a switch (ON), the relay closes the circuit and the light lights up for a previously defined period of time (wiping time). The relay then automatically interrupts the circuit again. It goes into sleep mode even if control power is still present (switch still ON). This scenario can only be repeated if the switch has been actuated (OFF) after the wiping time has elapsed. If the switch is confirmed (OFF) during the wiping time, the control voltage is interrupted and the relay also interrupts the circuit immediately. The rest of the wipe time is deleted. The process can start over.Scenario 8 - The fleeting switch-off relayExample: When switching off the control voltage using a switch (OFF), the relay closes the circuit and the light lights up for a previously defined period of time (wiping time). The relay then automatically interrupts the circuit again and goes into the idle state. This scenario can only be repeated if the switch has been actuated (ON) after the wiping time has elapsed. If the switch is confirmed (ON) during the wiping time, control voltage is applied again and the relay interrupts the circuit immediately. The rest of the wipe time is deleted. The process can start over. A classic use case: you leave a building in the dark and switch off the main light. The orientation lights turn on and you have time to leave the building. After that, the orientation light also switches off automatically.Scenario 9 - The fleeting on and fleeting off relayThe circuits from scenarios 7 and 8 are combined with each other.Example: When the control voltage is switched on using a switch (ON), the relay closes the circuit and the light lights up for a previously defined period of time (wiping time). The relay then automatically interrupts the circuit again. It goes into sleep mode even though control power is still present (switch still ON). When the control voltage is switched off using the switch (OFF), the relay closes the circuit again and the light lights up again for the specified wiping time. When this expires, the relay breaks the circuit, turns off the light and goes into sleep mode.Scenario 10 - The time relay as a pulse shaperThe application of the control voltage (regardless of whether it is long or short) is converted into a switching process of the same length.Example: You press a switch (ON) to start the scenario. The relay closes the circuit for a previously defined period of time. The light glows. After the time has elapsed, the relay opens the circuit again and goes into the idle state. The light goes out. It is irrelevant whether you press the switch again while the light is on (OFF) or whether you do this much later, when the light has already gone out. The process only starts again when control voltage is applied again (switch ON).This is how you saveMany of the scenarios described can be implemented with multifunction time relays. So you are always flexible and only have to invest in one device.In addition, it is also possible to combine several time relays with one another in order to create corresponding dependencies.

Contactor relay - Contactors are divided into power contactors and auxiliary contactors. The eibabo catalog offers a wide range of auxiliary contactors and contactor relays for all applications. Typical uses of contactor relays are control purposes and the automation of switching processes. Auxiliary contactors are, unlike power contactors, mostly designed for switching currents of up to 6A. Among the auxiliary contactors are, among others, time relays and safety relays for electrical installations. When the switch of the auxiliary contactor is operated electromechanically, a control current flows through a magnetic coil and the resulting magnetic field draws the contacts into the active switching position. When the current no longer flows, the initial state is restored due to the built-in return spring. Contactors and auxiliary contactors operate similar to a relay, but are designed for higher switching capacities. An auxiliary contactor relay is not different from a conventional low-power relay, but its design is similar to that of a normal contactor. If the auxiliary contactor relay is used together with another contactor or power contactor, the term 'auxiliary contactor' is used. This indicates that the auxiliary contactor does not switch power but merely assumes switching functions and control functions. Many auxiliary contactors are usually 4-pole in their basic version and can be extended by means of a combination with auxiliary switch blocks to several poles (eg 8 poles). Many contactor relays are designed for both AC operation and for DC operation. When choosing your required contactor make sure that the chosen contactor is suitable for the function. Our shop provides a wide selection of high-quality relays and contactor relays: auxiliary contactors are available with screw connection or spring terminals and, depending on the type, are suitable either for mounting on a top hat rail / DIN rail or screw mounting. The auxiliary contactor relays have standardized connection designations and help you to save time and money through an optimized and effective connection system.Catalogue content:In this eibabo® catalogue Low-voltage industrial components > Contactor relay you will find items from the following product groups:Item overview:AC contactorAuxiliary contactorAuxiliary contactor with alternating currentAuxiliary contactor with direct currentAuxiliary contactor, relayBuilt-in deviceBuilt-in distributor deviceContactorContactor moduleContactor relayControl circuit relayControl contactorCoupler Auxiliary ContactorCoupling relaysDC contactorInstallation contactorInterface relaysItemized listLittle AuxiliaryMini-relayMiniature relayModular installation devicePlug-in relayPrint relayRelaySmall auxiliary contactorSmall contactorUniversal relayfrom the following manufacturers:Manufacturer overview catalogue Contactor relay:ABBDoldEatonEberleGlen DimplexMetzMurrelektronikRockwellSchalkSchneider ElectricSiemensTele
Heating actuator - A comfortably warm bath after getting up or a cool bedroom at night - automatically. Who does not want that? Modern building automation makes it possible. The interaction of room temperature controllers, heating actuators and valve drives offers almost unlimited possibilities. The setup can be set up in all rooms according to the needs of everyday life.What are heating actuators?If you want to regulate the temperature in the room, in the apartment or in the entire building automatically, heating actuators play a central role. In principle, these are switching actuators. However, these are not equipped with mechanical relays. Thermoelectric valves (low ohmic loads) work here, which use electronic circuits (Triac) to ensure closed hot water circuits or chilled water (chilled ceiling). As a result, these devices are noiseless and wear-free.How is room temperature controlled via a heating actuator?The control difference determined by a KNX room temperature controller, i.e. the difference between the setpoint temperature and the actual temperature, is converted into a command value telegram. It is sent to the corresponding channel of the heating actuator via the KNX bus. Connect the thermoelectric (conventional) actuator to the duct using a suitable cable (e.g. NYM-J 3x1.5). The heating actuator can switch directly (1 bit) or independently process a received 1-byte command value signal internally. With the latter, the KNX bus is relieved because there is no flood of control telegrams from the room temperature controller to the actuator. Only the calculated control difference is sent to the actuator as a 1-byte command value telegram (0-100%). This converts the information into switching signals (on/off) directly to the assigned heating channel. This is called pulse width modulation (PWM). TIP:Make sure there are enough control channels on the heating actuator, ideally at least one per room. This creates maximum flexibility when controlling. The following small example illustrates the rough functionality, not the actual, manufacturer-specific control algorithm:The current temperature (controlled variable) is 20 degrees Celsius. The desired room temperature is 25 degrees Celsius and represents the set value for the controlled variable (command variable). The difference between the desired room temperature (set value) and the current temperature (actual value) is the control difference. The control difference is 5 degrees Celsius and is used to determine the manipulated variable that influences the room temperature. Assuming the manipulated variable is 20%. This value is sent to the heating actuator in the form of a 1-byte telegram (0-255 = 0-100%). The value 51 is therefore transmitted to the actuator. The time for opening/closing the actuator is stored in the parameters of the actuator using ETS. You can find this time in the properties of the respective 230V AC or 24V DC thermoelectric actuator. For example, the actuator takes 2 minutes to fully open. With a command value specification of 20%, the actuator would switch on the valve drive for 24 seconds (20% of 2 min.) and switch it off for 96 seconds. This process is repeated until the room temperature controller calculates and sends another command value specification. Depending on the manufacturer of the actuator, you can integrate several actuators per channel.How do I find the right heating actuator?The selection of a suitable heating actuator is linked to certain requirements. Answering the following questions will help you make a decision:How many heating circuits does my system have?How many actuators do I have per heating circuit?Do I want to install the heating actuator centrally or directly in the heating circuit distributor?Do I want to protect the power supply of the device via a connection for auxiliary voltage?With what voltage do the actuators work?Which functions should the heating actuator have?Do I prefer a certain brand?and many more The range of functions of a heating actuator in particular can differ depending on the model. Things to keep in mind include the following:Is it controlled with 1bit (switching/PWM) and/or 8bit (continuous) control values?Is direct control with a temperature value possible via the KNX bus?Does the device have an integrated temperature controller?Are the setpoints saved in the event of a bus voltage failure?Is there an emergency operation if the cyclic command values fail?Are different operating modes available (comfort, night, frost protection, summer mode or winter mode)?Is there a short-circuit detection and a voltage failure detection?Does the device have a pump shut-off? High comfortDepending on the model, it is possible to set a minimum comfort temperature for the underfloor heating. An additional sensor measures the temperature of the floor and keeps it at your comfort level. This is very pleasant in barefoot zones such as a bath.Depending on what value you place on the individual properties, the range of products can be limited to just a few models.Can I connect a heating actuator directly to the actuators in my heating circuits?In the case of a decentralized installation, for example in the heating circuit distributor, models with L and N connections can be used for direct connection of the actuators.Are KNX actuators really bad?Thermoelectric actuators are not wear-free and should be replaced every year. That is why expensive KNX actuators, which combine the KNX actuator and actuator, have not caught on and are disappearing from the market.Image: Jung Triac 2336-REG-HZR-HE 6-fold KNX heating actuatorHow are thermoelectric actuators installed?Thermoelectric actuators (valve drives) are snapped or screwed directly onto the upper part of the valve used in the house. This connection with the valve spindle is usually made directly in the heating circuit distributor. You can use adapters made of PVC or metal to compensate for the manufacturer-specific distance differences between the drive and the upper part of the valve or the thread and the mount. In this way you ensure correct implementation of the manipulated variable.How do I prevent rapid wear and tear on my valve drives?The ETS parameter 'Flush' minimizes wear and tear on valves that are rarely used, for example in summer or in bedrooms. This function prevents rapid calcification of the heating valves. Good to knowWith actuators, a distinction is made between NC (normally closed) and NO (normally open). NC drives open when power is applied. In NO actuators, the current closes the valve. Please bear this in mind when planning your heating system, as it is ultimately your personal decision. In the event of a power failure or defect, NC drives close and you quickly notice a malfunction. These drives only consume electricity when heating. On the other hand, drives that open without current are more efficient during the heating period. In this case, switching off the pump by the heating actuator after the winter season would be advisable. Otherwise you would continuously use electricity to keep the heating closed by means of the NO actuators in the warm season.Who are the leading manufacturers of KNX heating actuators?The leading manufacturers of KNX heating actuators at eibabo® are, for example, ABB, Berker, Busch-Jaeger, EIBMARKT, Elsner, Gira, Hager, Jung, Lingg & Janke, MDT, Merten, Siemens and Theben. We have more than 25 years of experience in the field of building automation and have arranged the order of the products in this catalog accordingly.
