Auxiliary contact block - Auxiliary switch blocks are an ideal supplement for auxiliary and power contactors. The auxiliary switch blocks we offer differ in design and mounting type, switching type (changeover, opener, closer) and number of contacts. Learn more about these devices in the following post. At eibabo® you will find a huge selection of high-quality auxiliary switch blocks with different specifications. These include:Execution of the electrical connectionType of installation and fasteningHeight of the rated operational currentand more Products such as the auxiliary switch block are among the low-voltage switching devices and are primarily used in electrical distribution installation and the installation of electrical distribution boards. Typical areas of application include engine controls and system controls, switching of lighting systems and multiplication of signals. Switch blocks expand the number of contacts with auxiliary contacts for control.Already knew?Contactors have auxiliary contacts and main contacts. The auxiliary contact is a mechanically operated contact in the auxiliary circuit. This is physically connected to the main contacts and is actuated simultaneously, carries less current and is called the auxiliary contact or control contact.Find out more about the function, structure and use of an auxiliary switch block in the following article.What is an auxiliary switch?An auxiliary contact or auxiliary switch is an additional contact within a circuit. This is used to regulate the amount of current that can flow through the system. Such a device is often installed when more current needs to flow than a single contact can handle. In practice, at least two contacts are then required. If there were only one auxiliary contact, under certain circumstances too much current would flow at one point in the circuit. This means: some areas receive no power, other areas receive more power than required. The amount of current flowing through the individual areas can be regulated with two or more contacts. This ensures that an even and correct power supply is guaranteed everywhere.How does an auxiliary switch work?When an overload trips a relay or fuse, the connected cable is also heavily loaded. In order to exclude the associated dangers, another, usually larger, switch can be controlled with an auxiliary switch. The auxiliary switch consists of a coil with high-current contacts and two sets of low-current contacts. In contrast to the coils of the main switch, these are not designed for continuous operation in the entire system. However, the auxiliary switch has delay functions. These prevent arcing and possible damage when opening the auxiliary switch while the main switch is still live.Image: Eaton DILA-XHI22 auxiliary switch moduleWhy should I use an auxiliary switch?They protect your circuit breakers and devices from damageSince auxiliary switches trip when a circuit is overloaded, the main switch or fuse are not overloaded. This protects your devices from damage caused by current spikes and heat build-up, to which your under-capacity fuses and circuit breakers would not respond. Auxiliary switches are often equipped with their own fuses. In the event of an overload due to a short circuit, its fuse will therefore trip without affecting the main circuit breaker. The auxiliary switch protects your devices from wear and tear, which would be caused by circuit breakers tripping frequently.You protect yourself from electrical hazardsAuxiliary switches ensure that no dangerous electrical faults occur due to the triggering of overloads. If an overload is not triggered, this may lead to:failures in the circuitsoverheating of componentselectric shocksfire hazard Auxiliary switches minimize these risks and ensure a safer working environment.They minimize the risk of power failuresAuxiliary switches minimize the risk of power failures because the circuit breaker is not overloaded. Even before fuses or circuit breakers trip, an overloaded circuit can cause overheating, damage to equipment, personal injury from electric shock, and other malfunctions. Auxiliary switches trip in the event of overloads before a critical level is reached. This ensures optimal performance and life expectancy for your electrical system.They increase the life expectancy of circuit breakersWithout an auxiliary contact, the circuit breaker would have to handle the additional current required by under-capacity circuits. This would degrade their ability to dissipate heat. And this leads to degradation of circuit breaker performance over time. Auxiliary switches limit the current and ensure that the main circuit breaker is not subjected to dangerous overloads.What is the difference between auxiliary switches and circuit breakers?A circuit breaker uses an insulating washer that separates the two sets of contacts. Protecting high currents and voltages on circuit breakers requires a lot of force to make a conductive connection. The classic useMost often, a circuit breaker with main contacts and auxiliary switches is used to control the operation of motor-driven equipment. When the device is not powered, a spring mechanism keeps the two sets of contacts apart. When the circuit breaker is actuated, the spring is released and the two contacts come together.An auxiliary switch requires less pressure to open and close. When closed, the two sets of contacts touch via a metal bridge. If there is a problem with the circuit breaker mechanism or an overload is detected, one pair of contacts will easily separate from the other. As a result, further protective measures can be taken, including opening the main contacts or turning them off completely. Auxiliary contacts are therefore used for monitoring, so that in the event of a malfunction, the main contacts can be opened before there is a problem with the device or the circuit breaker.As a leading specialist center for electrical engineering, the eibabo® technology store only offers you high-quality auxiliary switches and auxiliary switch blocks.

Combined arresters - eletric - Are you looking for combination devices to divert lightning currents and surge voltages for your electrical installation? But you are still not sure what requirements such a device has to meet? Learn more here. In order to be able to decide on a specific device, you must be aware of the dangers caused by lightning currents or surge voltages. Admittedly, these events are rare and often only last a few milliseconds. Nevertheless, major damage can result. We therefore always recommend appropriate protective measures to prevent damage to buildings and sensitive electronic devices. We support you in choosing the right item.Image: Dehn DSH-TNS-255 combined arresterWhat are combined arresters in power engineering?Combined arresters are of enormous importance for safety in electrical engineering. These limit lightning currents and overvoltages in electrical lines and divert them. Combined arresters are therefore used to protect sensitive devices such as computers, televisions or hi-fi systems.But what requirements do these devices combine?To understand this, we need to take a closer look at the overvoltage phenomenon. In Germany and large parts of Europe, the mains voltage is 230V. Overvoltages go well beyond this value. These are caused by switching operations by the network operator, lightning strikes, short circuits or electrostatic discharges. The resulting consequences depend on the level of the overvoltage, the duration and the speed of the voltage pulse. If suitable protective measures are missing, fires can break out or people can be injured. Since the type and extent of a fault caused by overvoltage and lightning current cannot be predicted, protective devices are constructed in three stages. We distinguish between coarse protection (type 1), medium protection (type 2) and fine protection (type 3). With each level, the overvoltage is further reduced until it can no longer pose a threat to the end devices. Combined devices for dissipating lightning current and surge voltage usually meet the requirement classes type 1 and type 2. In the following text we will explain in more detail what this means.Surge arresters and combination arresters are also referred to as Surge Protective Devices (SPD). They are usually installed in the installation distribution board or in the sub-distribution boards between the active conductors and earth. The devices are usually designed as pluggable modular devices or as devices for mounting on DIN rails. Other properties, some of which are optional, are:connectable lightning current and surge arrestershigh discharge capacity for lightning current surges up to 100 kA (10/350?s)optical status display / defect displayremote signallingshockproof and tolerable to vibrationsConnections can be labeled The construction of a lightning protection system with overvoltage protectionIn order to be able to decide on a specific combination arrester, you should know the entire structure of a lightning protection system with overvoltage protection.side noteBuildings are classified in lightning protection classes I to IV. This assesses the risk of lightning strikes. The class in which a building is to be classified depends on its type, use and the damage to be expected. The lightning protection class determines the structure and dimensioning of the lightning protection system.Whether a combination device is suitable for a building with a specific lightning protection class can usually be found in the product description. Lightning is high-energy and carries very high lightning currents. In the case of overvoltages, the currents and energy are small, but the charge difference between two potentials is very large. In order to counteract these dangers completely, such a system consists of three parts:the external lightning protectionthe internal lightning protectionthe overvoltage protection The external lightning protectionAs the name suggests, external lightning protection is protective measures outside the building. These are lightning arresters, lightning conductors, earthing, fixings and so on. The external lightning protection diverts direct lightning strikes and the associated high lightning current into the ground before they reach the building. In Germany there is no obligation to install external lightning protection systems. Exceptions are buildings which:are over 20 meters highstanding free on a hilltophave a combustible roof (e.g. thatch or thatch)are open to the public (cinema, museum) However, external lightning protection always makes sense, even if your building does not meet any of these criteria. A lightning strike can cause serious damage. Information and high-quality items for setting up reliable external lightning protection can also be found here in the shop. Use our intelligent search.The internal lightning protectionEffective internal lightning protection and overvoltage protection protects apartments, buildings, industrial plants and the devices in them. The internal lightning protection is designed as equipotential bonding. For this purpose, all metallic pipe installations and cable installations in a house are connected to each other and to the main earthing bar. This can prevent voltage differences, lightning flashovers in the building and the resulting danger to people and technology.The overvoltage protectionInternal lightning protection includes overvoltage protection. This is where the combined arresters offered in this catalog come into play. In order to be able to select a suitable device, please consider the type of possible interference as well as the type of devices to be protected. As already mentioned, the overvoltage protection has a three-stage structure. Accordingly, three requirement classes for overvoltage protection devices are also available. We distinguish between type 1 (rough protection), type 2 (medium protection) or type 3 (fine protection). Type 3 standard devices provide fine protection and protect against voltages up to a certain level. Enhanced Type 2 devices provide additional protection against transient voltage spikes. The high protection standard of type 1 also protects against impulse currents. But what exactly does that mean for the combination arresters offered here, which in many cases meet the requirements of types 1 and 2? NoticeSurge protection has been a mandatory part of an electrical system in Germany since December 2018 and must be installed in new buildings. Type 1 surge protective devices are also known as lightning arresters. These divert high lightning currents via the internal or external lightning protection of a building. The residual voltage is reduced to a level between 6000 volts and 1300 volts. However, this basic protection is not yet sufficient to protect the end devices.Type 2 surge protective devices provide medium protection. The residual lightning voltage, which is already reduced by the type 1 devices, is further reduced in this stage to values between 2000 volts and 600 volts. Type 2 devices also limit dangerous transient overvoltages. These are caused by the switching of motors, transformers, circuit breakers or inductive loads. Disturbances of this kind are short-lived. However, these occur more frequently and cause the tension to rise suddenly.Type 3 protective devices further reduce the remaining overvoltage. This fine protection is installed as close as possible to the end devices to be protected.What should you pay attention to when buying a combi arrester?You are now familiar with the structure of a lightning protection system with overvoltage protection. With the installation of combination devices, you usually cover the requirements of test classes type 1 and type 2 with just one device. When buying, pay attention to high-quality components from trusted and well-known manufacturers. We also recommend retrofitting surge protection in older buildings, because the number of devices with sensitive electronics in our households is constantly increasing. When buying, also pay attention to:mounting typeRated voltage AC/DCHighest continuous voltage for AC and DCDissipation capacity for lightning current surgesnumber of polesSuitability for buildings with a special lightning protection classProtection level (must not exceed the impulse withstand voltage of the installation and the connected equipment) Considering your electrical installation in connection with the assessment of your individual protection requirements will help you to choose the right combination arrester. TIP:With a combination device, you save money and space in the control cabinet. You get easy-to-install, comprehensive protection. At eibabo® you can get a large selection of combination arresters for electrical engineering in different designs. These include: CombiController, lightning current arresters, arresters for busbars, combined arresters for meter applications, type 1 + type 2 combined arresters.

Combi earth leakage circuit breaker - How do you protect yourself from fires in electrical installations? Which devices prevent fires? How do you find the right fire protection switch and what specification should you pay attention to? This eibabo® catalog contains combination RCCBs/line protection with a focus on fire protection. Did you know that about a third of the fires in Germany inside buildings have an electrical origin? Three quarters of this can be traced back to electrical devices or the electrical installation. How can you face this danger? Electricity is omnipresent and it is impossible to imagine our everyday lives without it. As a rule, the classic measures for protection against overload, short circuits and residual currents are considered sufficient and comprehensive fire protection is therefore also assumed. But this protection is not unlimited. In this article, we will bring you closer to the function of suitable fire protection switches and arc fault circuit breakers.Image: ABB DS ARC1 C20 A30 fire protection switchWhat is a combination RCD/line protection with fire protection function?If switches for fault currents and line protection are combined, this results in FI/LS combination switches. These protective switching devices combine the functionalities of residual current circuit breakers and miniature circuit breakers. What are these properties? A residual current circuit breaker prevents you from getting a dangerous electric shock if you touch something that is live. This switch provides personal protection that ordinary fuses and a circuit breaker cannot provide. A circuit breaker is an electromechanical device used to protect a circuit from excess current caused by either an overload or short circuit. So while a residual current circuit breaker only protects people from electric shocks caused by ground faults and a miniature circuit breaker is only used to protect against overcurrent, the combination of both switches offers comprehensive protection against both types of faults.Good to knowAn arc fault switch is an arc flash detection device. Its purpose is to detect the presence of dangerous electrical arcs and to isolate the affected circuit.Added to this protection is another safety feature - arc flash detection. Devices with this capability are referred to as fire circuit breakers, arc fault circuit breakers, or AFDD. The abbreviation AFDD stands for the English term 'Arc Fault Detection Device'.Why do I need a fire protection switch?Fusing with an RCBO combination switch already protects against many dangers. But there is a kind of error that the classic RCBO combination switch does not recognize. These are arcs within a cable or connection. But what is an arc? An electrical arc occurs when electrical current crosses a physical separation between two conductive materials. If only little current flows, a short-term spark is produced. If the current is high enough, a continuous arc is generated. This can result in temperatures of over 6000°C and gaseous air turns into plasma. In principle, arcs are not a problem as long as they are generated in a controlled manner, for example in an electric motor or in a light switch. However, when accidental arcing occurs in a circuit, a fire can occur due to the intense heat from combustible materials. Common causes are:Damaged insulation of current-carrying conductorsFaulty cable connections and line connections These causes are often caused by improper handling. These include:kinking, crushing and twisting of cables and linesdamage caused by screws, nails or drillsloose connections between two cable endsPoor cable protection and mounting (damage from mechanical stress, movement or rodents) To minimize the risk of fire from these faults, fire protection switches have arc fault protection devices and offer protection against serial and parallel arc faults. A serial arcing fault occurs between two parts of the same phase of a line. A parallel arcing fault occurs when the arc occurs between the phase conductor and either the neutral conductor or the earth conductor.How does the arc fault protection device work on a fire protection switch?Fire protection switches continuously monitor the waveform of the electrical current flowing through one or more circuits. Arcs affect this current flow. If the device detects an unusual signature in the wave, the circuit is broken. 'Normal' arcs that occur during the operation of electrical systems (e.g. in the electric motor) are recognized by the device as harmless. With these, the protective mechanism does not trigger. But beware! A fire protection switch does not recognize:Phase-to-earth fault such as a residual current circuit breakerLine-to-neutral fault like a circuit breakerOverload like a circuit breaker For this reason, the fire protection switches are usually available in combination with RCBOs or are combined with them in the control cabinet.When should I buy a combination RCD/line protection with fire protection function?Basically, we always recommend not to save on your own safety. Even if a fire protection switch is not necessary to protect all circuits, the damage in the event of a fire is usually higher than the additional costs for such a device. Of course, you have to weigh the risk yourself. In certain facilities and parts of the building, however, the use of a fire protection switch always makes sense. This can be:Institutions with valuable goods (jewelers or museums)Rooms with combustible contents (barns, laboratories)oxidizing structures (chimneys, elevator shafts)Buildings open to the public (hotels, retirement homes, youth hostels, hospitals) If you decide against the installation of fire protection switches, please pay attention to the smell of burning from cables or sockets in everyday life. It doesn't have to be an arc fault, but if you smell burnt, you should always look for the cause. Also, if any cord or appliance feels hot to the touch, turn off the affected circuit immediately and, for permanent installations, contact an electrician.for your safetyFire alarms and smoke alarms are additional safety devices that you should never do without in your building. You will find high-quality and reliable devices in our shop. Use our intelligent search.Beware of rapid 'clicking' noises and burn marks on electronic devices. Turn off the affected circuit and have an electrician check the system.What types of fire protection switches are there?As a global electronics retailer, the eibabo® technology store has an extensive range of fire protection switches. Available are:stand-alone devices that you can install in series with a suitable protective device (miniature circuit breaker or residual current circuit breaker).Device combinations that unite the fire protection switch with a combination RCD/line protectionAdditional modules for other protection devices, which are usually only compatible with the protection devices of the respective manufacturer What should I look out for when buying a combination RCD/line protection with fire protection function?The choice of the right switch depends on the tripping characteristics, as is the case with classic RCBOs. There are, among other things, type B and type C combination switches. The main difference lies in the tolerance to the strength of the current surge, which leads to the disconnection of a circuit. TIP:Higher inrush currents can occur when lighting or motors are switched on. Your selected device must be able to distinguish these load peaks from actual errors. Devices with B characteristics are typically used for normal household and non-critical commercial applications. These trigger at residual currents that correspond to three to five times the nominal current. Choose type C devices for commercial and industrial applications. These trip at five to ten times the nominal current.Make sure you choose a reputable manufacturer. With no-name devices, reliable operation cannot be guaranteed and they deviate significantly from the specified values. In our shop you only get the best quality from leading manufacturers such as ABB, Doepke, Eaton and Hager.  Catalogue content:In this eibabo® catalogue Circuit breakers and fuses > Earth leakage circuit breaker with auxiliary device you will find items from the following product groups:Item overview:AFD switchAFDDArc faultArc fault protectionArc fault protection deviceFire protection switchFire protection switching deviceFire switchModular installation devicePersonal protection machinefrom the following manufacturers:Manufacturer overview catalogue Combi earth leakage circuit breaker:ABBDoepkeEatonHager
Led lamp multi-led - Don't you think that the era of conventional light bulbs is coming to an end? The range of LED bulbs has taken over the lighting market and is now wider than other types of bulbs. Find out here how the LED lamp has developed over the last few years and why you should replace the conventional lamps you may still have with modern technology.The decades in which conventional incandescent lamps dominated domestic lighting are over. The future belongs to LED lamps, which have been developed in a wide variety of types and shapes in recent years. These are now used everywhere at home, in offices, hotels and public buildings as well as in industry. Even in concert technology, theater lighting and municipal lighting, LED technology has become indispensable.Image: Philips MLEDspotVal LED reflector lampWhat are the advantages and disadvantages of an LED lamp?An LED lamp is a rather complex electronic device with dozens of details that affect the quality of light, safety and lifespan of the lamp. There are numerous differences compared to classic incandescent lamps and the modern compact fluorescent lamps (energy-saving lamps). These have some advantages, but also come with a few disadvantages. NoticeThe main advantage of LED lamps is energy saving. With the same light output, the LED lamp consumes 7 to 10 times less electricity than a conventional incandescent lamp. Other differences are:Durability - the LED bulb lasts 15x to 50x longerLess heat development - the lamp usually does not get that hotLED lamps shine with the same brightness despite the lower mains voltageInstallation ? lower power consumption allows installation in a power-limited luminaireThe light from modern LED lamps is optically comparable to that of conventional incandescent lamps Compared to compact fluorescent lamps (energy-saving lamps), there are the following advantages:Environmental friendliness - LED lamps do not contain any hazardous substances such as mercury.Economy ? The LED lamp consumes less energy with the same luminous flux.In contrast to the compact fluorescent lamp, the LED lamp lights up immediately with full brightness.Compact fluorescent lamps have an unnatural light spectrum. The light spectrum of an LED lamp is much closer to natural light. But there are also disadvantages:The price of an LED lamp can be higher than other lamps.Due to the complex structure, numerous products of poor quality are on the market.Not all models support dimming.The performance specifications of some manufacturers deviate from the actual performance. Briefly on the history of the LEDThe history of the LED begins as early as 1907. British engineer Henry Joseph Round first observed the formation of a point of light when direct current is passed through a silicon carbide point contact connection. In 1924, it was Oleg Vladimirovich Losev who investigated this effect in more detail and then constructed the first light-emitting diode (LED). After initial research, Losew proposed concrete theories of how it works and later used them in practical applications. Based on this, red, yellow, green and blue LEDs were developed in the 1970s and 1980s. Subsequently, white LED light sources were created from the combination of red, green and blue. In the 1990s, the first white LEDs appeared, which used a special chemical to convert the light from a blue or ultraviolet LED into white light.What types of LED lamps are there?As already mentioned, the range of offers is very wide. LEDs are not only available as individual components for self-assembly, but also in the form of strips, tubes or panels. In this catalog from the eibabo® shop, we present the LED versions of classic light sources. In other words: Here you get the LED alternatives to all possible types of incandescent lamps, halogen lamps and fluorescent lamps. The LEDs are installed in housings that resemble the original light sources. These can be classic lightbulbs, candles, spheres, spotlights or spotlights. The housings are equipped with the corresponding, standardized bases to enable easy replacement with the conventional variants. The most common sockets are:E27, E40 and E14GU10 and GU5.3G9, G13, G23 and G4GX53R7sand some others What are COB LEDs?Anyone who deals with the selection and differences between individual LED lamps will come across the term COB LEDs. COB LEDs are multiple LED chips that are grouped and bonded together by the manufacturer to form a single module. As a result, the chips are smaller and can be installed closer together. The LED chips are mounted directly in contact with a substrate such as silicon carbide or sapphire. This achieves a significantly higher lumen density in a smaller space. COB technology also uses a single circuit design with only two contacts, no matter how many chips are involved. And what does this mean? In contrast to other LED light sources, there are no longer any transitions in the light from one LED to the next. A uniformly luminous field of any shape and size is created.The term COBCOB is the abbreviation for 'Chip on Board'. This means that the chips are attached directly to a carrier substrate and therefore fewer components are required per LED chip for proper operation. Along with eliminating the otherwise common LED chip structure packaging, less heat is generated and higher installation density is achieved.This technology made it possible, for example, to produce flexible and yet optically uninterrupted light strips. The filaments in the currently very popular 'Edison light bulbs' are also based on COB technology.What characteristics should I look out for when buying LED lamps?There are numerous parameters that can influence the purchase of an LED lamp. Let's take a closer look at some of them:The luminous flux / luminous fluxThe luminous flux is given in lumens and is the total amount of light that the lamp emits in a certain time. The more lumens, the brighter the lamp.the frequencyNatural light sources shone evenly, like candles or the sun. Many electric light sources do not emit an even, but a pulsating light. At a frequency of 50 Hz, the light 'flickers' 50 times per second. Even if we are not consciously aware of this, our body registers the pulsation and may react with discomfort, tiredness and even malaise. Light with a frequency above 300 Hz has no noticeable effect on the human body. So pay attention to the highest possible frequency.The color temperatureLED lamps are available in different light color temperatures. These are given in Kelvin, for example:1800K - Candlelight2600K - warm light like incandescent bulbs3000K - warm white comfortable light5000K - neutral white daylight6000K - Cool White Light White and cool white light is said to increase concentration and efficiency, while warm light promotes relaxation. Warm lighting is recommended so that you can fully relax and fall asleep better after coming home from work. Color temperatures of around 3000 Kelvin are suitable for everyday household routines. It can be daylight to work.In addition to the main parameters, it is important to note some other characteristics of LED lamps. These would be:Illumination angle ? width of the cone of light illuminating a given areaOperating voltage ? Most LED lamps are designed for a mains voltage of 230 V, lamps with GU5.3 and G4 sockets are also available for 12 voltsEnergy Consumption - Typically, the wattage of the lamps is in the range of 1.5 watts to 15 watts. However, this says nothing about the actual brightness. This is given in lumens (see above)Dimmability ? There are dimmable and non-dimmable models. Many dimmable LED lamps do not dim completely, but only to 15% to 20% of full brightness. This depends not only on the lamp, but also on the dimmer.Dimensions - When choosing lamps, don't forget the overall dimensions. LED lamps are sometimes significantly larger than the corresponding light bulbs. As a result, a bulb may not fit into the lamp or protrude.Service life ? The service life is mostly given as between 10,000 and 50,000 hours. Be aware that these are theoretical values.Guarantee period - The longer the manufacturer gives a guarantee on a lamp, the more likely it is that it will be of the highest quality.Date of Manufacture ? Technology is evolving rapidly. If lamps have been stored for a long time, you will surely find better models from more recent productions.  TIP:The indication of the power equivalent to an incandescent lamp is no longer up-to-date (e.g. 'corresponds to 40W') and is also becoming less and less relevant as technology continues to improve. Instead, select your lamp based on the lumen specification. Buy your multi-LED lamp from eibabo® now.

Inductive proximity switch - Are you interested in an inductive proximity switch and would you like to learn more about how it works and areas of application? Would you like to buy an inductive proximity switch and are you looking for a reliable supplier with a large selection at top conditions? In addition to information, the eibabo® shop also offers you high-quality articles in the field of Smart Home, lighting, switch programs and electrical material. Of course, this also includes inductive proximity switches and many other types of position switches and limit switches.What are inductive proximity switches?Inductive proximity switches are used to detect metal objects in the working area of a sensor and to signal this by changing the switching status.StoryThe physicist Michael Faraday first described the principle of electromagnetic induction in 1831. He found that changing magnetic fields create electric current.Proximity sensors are used for automatic non-contact detection of metallic objects for various industrial purposes and work reliably even under difficult conditions and various external influences. When the sensor is supplied with electricity, a magnetic coil inside generates an alternating magnetic field. This magnetic field is the working range of the sensor. The principle of operation is based on the phenomenon of change in vibration amplitude caused by a ferromagnetic, magnetic or metal object of a certain size in the working area of the sensor. If you bring a metal object into this area, the eddy currents induced in the metal lead to a change in the original oscillation amplitude of the coil. The intensity of the change depends on the distance between the metal object and the sensor. This change is presented as an analog signal and is converted into a logic signal with a corresponding value. The switch itself is a semiconductor converter, which controls the circuit to be executed depending on the position of the object.How are inductive proximity switches constructed?The electrical part of the sensor is typically housed in a threaded metallic cylindrical housing or a rectangular plastic housing. The cylindrical metal housing is assembled using the thread. To do this, they are attached to bores in mounting plates using nuts or screwed directly into the sockets provided for this purpose. The sensors with a rectangular housing are fastened with screws at the place of use. In order to be able to withstand the conditions of the industrial environment, the technology is usually surrounded by a protective sealant. TIPThe electromagnetic field of the inductive proximity switch is very weak and harmless to human health. The switches are available for both flush and non-flush mounting. Flush sensors can be mounted without protruding beyond the mounting surface. However, these generally have a shorter sensing range or more restricted working range than non-flush sensors.What properties do inductive proximity switches offer?The properties of the inductive proximity switches can vary depending on the model, manufacturer, structure and equipment. In general, the devices offer the following functions and properties:reaction to metal onlyInsensitivity to other materialsTightness against water and dust / correspondingly high degree of protectionReliability and durability because the switch's working surface is not in contact with the objectCompact dimensions and low weightTrip indicator LED Image: Schneider Electric XSAV11801 speed monitorWhere are inductive proximity switches used?Inductive proximity switches are robust and withstand shock, moisture, vibration and dirt. Within an automation process, inductive proximity switches work as the primary control elements, taking into account the position of certain metallic, moving objects. Proximity switches are used particularly frequently on assembly lines in special machine construction and plant construction. These are used there, among other things, for counting and tracking metal objects. But the devices are also used in warehouse logistics and conveyor technology, in the packaging industry and in the automotive sector. Depending on the application, the signals from the proximity switch are evaluated by a counter, a motion controller, an alarm system or other devices. In addition to numerous other functions, the following are also:distance measurements madeMaterial thicknesses and material widths determinedChecked surface texturePosition checks carried outCounting tasks taken over The classic example are bottles with crown caps or beverage cans, which are transported past the sensor and counted on a conveyor belt.What errors can occur with inductive proximity switches?The reliability of the measurements of an inductive proximity sensor depends on its properties, the way it is used, the installation and the nature of the objects to be detected. The two main errors are:The item is not recognizedIf the object is not detected, please check the sensor properties and all distances. Pay attention to the switching distances and the switching function (opener or closer). Is the correct operating voltage present? Is the item made of metal? Is the item big enough? Is the object moving too quickly through the work area?The sensor switches too early or too lateIf the switching time is not correct, this is often due to critical environmental conditions or electromagnetic interference signals. Is the sensor installed correctly (flush or non-flush)? Were other installation conditions observed? Are other switches that are in the immediate vicinity interfering? Is the sensor dirty? Check if other metals affect the work area.The inductive proximity switches in the eibabo® range are all of high quality and are therefore also suitable for your planned application. Well-known brand manufacturers for inductive proximity switches are Baumer, Dietz, Festo, Kisling, Leuze, Metz, Pilz, Rockwell, Turck, Weidmüller and many others.  Catalogue content:In this eibabo® catalogue Sensors > Inductive proximity switch you will find items from the following product groups:Item overview:Analog sensorCable sensorCuboid sensorDC voltage sensorFour-wire sensorInductive sensorObject detectionPlug sensorProximity initiatorProximity switchRound sensorThread sensorThree-wire sensorUniversal voltage sensorUprox sensorfrom the following manufacturers:Manufacturer overview catalogue Inductive proximity switch:BaumerBernsteinDi-soricDietzEatonEGE-ElektronikElobauFestoGavazziHengstlerIfm ElectronicIpf ElectronicKisslingKlaschkaLandefeldLeuzeMetzOmronPepperl + FuchsPilzRockwellSchmersalSchneider ElectricSensopartSickTurckWeidmüller
Time switch mechanical - Timers are super practical because they regulate electrical switching processes for us without us having to think about it ourselves at the right time. These processes can be one-time or recurring on a regular basis. The mechanical timers and timers from the eibabo technology store can fulfill different functions. On the one hand, they can be programmed with one or more on and off phases that recur regularly after certain time intervals. On the other hand, there are timers that work in a similar way to a classic egg timer and trigger a one-time switching process after a certain, self-adjustable period of time has elapsed. Whatever model you need, we will deliver it to your home quickly and cheaply.Catalogue content:In this eibabo® catalogue Domestic switching devices > Timer for domestic switching devices you will find items from the following product groups:Item overview:Adapter plugCloserControl unitDelay switchElectronic time switchElectronic time switch for installation switch programsElectronic timerFront installationIlluminated pushbuttonIndicator lightInstallation switchLocking functionMechanical time switchMechanical time switch for installation switch programsMechanical timerPlug adapterPush buttonSelector switchTime automatic switchTime relayTime switch insertTimerTimer clockTimer for domestic switching devicesTimer for installation switch programsTimer mechanicalTimer useTimersfrom the following manufacturers:Manufacturer overview catalogue Time switch mechanical:BerkerBusch JaegerGiraHeliosJungLegrand BticinoMertenPehaSiemens
Staircase lighting timers - Staircase timers are typically part of a parallel circuit with several pushbutton switches and lamps. The light is switched on by pressing any button. The time switch ensures that the light does not stay on all the time, but goes out again within a specific and individually adjustable time interval. The name of the staircase light time switch comes from the fact that this type of light control was and is very often used in multi-storey stairwells. Of course there are other possible applications, especially if you use the tracking function. Some high-quality and yet inexpensive staircase lighting timers available in the eibabo online shop have this option, with which you can start the timing from the beginning by pressing a button in the meantime without the light going out.Catalogue content:In this eibabo® catalogue Devices for distribution board-/surface mounting > Staircase lighting timer you will find items from the following product groups:Item overview:Advance warning dimmerAutomaticAutomatic staircase lightBuilt-in deviceBuilt-in distributor deviceBuilt-in moduleFlush-mounted boxHalf light moduleHalf light time switchLong-term switchingMini circuit breakerModular installation deviceRelayStair light switchStaircase light time switchStaircase lightingStaircase lighting timerStaircase switchStaircase timerStaircase timer switchSurface-mounted stair light switchTime relayTime switchTime switch clockTimerTimer clockTimer relayTLZfrom the following manufacturers:Manufacturer overview catalogue Staircase lighting timers:ABBBusch JaegerDoepkeEatonEberleElsoEltakoFinderGrotheHagerJungLegrand BticinoSchalkSchneider ElectricSiemensTeleTheben
