Speaking of relays, it may not be clear to non-professionals about its specific functions, but in fact it can be seen everywhere in our lives and its application is quite extensive. Automotive Relay  is an electronic component commonly used in automatic control systems for switching circuits on and off. In daily life, you insert the car key, the car can start normally; press the horn, the car can whistle normally; return home, press the remote control, the air conditioner can send a slight breeze . These are all due to different electronics Precision control of relays in the device. But in the daily use process, the relay also faces a lot of problems: the given current is too large to burn the coil, the relay is too small to work stably; the contact switching voltage and current must also be kept within the normal range, otherwise the relay is easily damaged At the same time, with the gradual popularization of the Internet of Things channels and 5G communication technology, people

Automotive Relays  are comprised of magnetic circuit systems, contact systems, and recovery mechanisms. The magnetic circuit system consists of iron core, yoke, armature, coil and other parts. The contact system consists of static reed, moving reed, contact base and other parts. The restoration mechanism is composed of a restoration spring or a tension spring.  Automotive Relays Installation method: 1. Installation direction If the installation direction is consistent with the direction of the relay's impact resistance, the performance of the relay can be fully exerted. It is recommended that the impact direction be perpendicular to the movement direction of the contacts and the armature, which can effectively improve the vibration and shock resistance performance of the normally closed contact in the non-excitation state. When installing, make the relay's contact axis parallel to the ground, which can prevent contact splash and carbon from falling on the contact surfa

As a  Relay Electronics Manufacturer , there is some knowledge about relays to share with you. 1. According to the use environment selection The environmental conditions used mainly refer to temperature (maximum and minimum), humidity (generally referred to as maximum relative humidity at 40 degrees Celsius), low air pressure (excluding heights below 1000 meters), vibration and shock. In addition, there are requirements for packaging, installation, dimensions and insulation. Due to the different materials and structures, the relays are subjected to different environmental mechanical conditions and are used under the environmental mechanical conditions specified by the product standards. It is possible to damage the  22F Relay , which can be selected according to the environmental mechanics conditions of the whole machine or a higher level. It is best not to use AC-energized relays around devices that are sensitive to electromagnetic drying or RF drying. DC relays should be sel

In a broad sense, all components with the ability to automatically complete the relay characteristics are called relays. The parameters of the electromagnetic relay, input and output circuits are all electrical parameters. X is the relay coil current value or voltage value. Y is the current value of the Relay contact loop. Relay consists of three parts. 19F Relay Reaction mechanism: accepts an input signal and transforms the signal into a physical quantity that causes the relay to operate. For example, the electromagnetic system of an electromagnetic relay. Intermediary: Provides a standard comparison of controls. For example:  19F Relay 's reaction spring or reed. Actuator: Change the electrical parameters of the output loop. For example: the contact system of the relay (or the part of the contact). Therefore, the relay is an electrical component that reacts and transmits signals. As a  Relay Electronics Manufacturer , what are the factors that affect the reliability

First, the contact is loose and cracked back The contact is the electrical contact part of the relay to complete the switching load. The contacts of some products are press-fitted by riveting. The main disadvantages are loose contact, cracked contact or excessive positional deviation. This will affect the contact reliability of the  T78 Relay . The loosening of the erasing point occurs, which is caused by an unreasonable size of the mating portion of the reed and the contact or an improper adjustment of the riveting pressure by the operator. Contact cracking is caused by excessive material hardness or too much pressure. For different materials, the contacts are made of different materials. Some of the higher hardness contact materials should be annealed for contact manufacturing, riveting or spot welding. The manufacturing of the contacts should be careful. Since the materials have tolerances, the length of each cut should be determined after trial and error. Contact manufacturing

As an  Automotive Relay Factory , there is some information to share with you. A relay is an automatic control device that changes the output when the input quantity (electricity, magnetism, sound, light, heat) reaches a certain value. The car relay is a relay used in the car. This type of relay has high load switching power and high impact and vibration resistance. The power supply in the car is mostly 12V, and the coil voltage is designed to be 12V. Because the battery is powered, the voltage is unstable; the environmental conditions are bad, the suction voltage V≤60%VH (fixed working voltage); the coil overvoltage allows 1.5VH. The coil consumes a large amount of power, generally 1.6 to 2 W, and the temperature rise is high. Environmental requirements are quite demanding: in the engine compartment, the ambient temperature range is -40 ° C ~ 125 ° C, other locations ambient temperature range is -40 ° C ~ 85 ° C; relays used in the engine compartment to withstand sand, water, salt Oi

　In life, we will use a small micro switch of 0.5a in addition to the tact switch with a current of only 50ma. But today is the  T78 Relay , which is often used in automated control circuits. It is actually an "automatic switch" that uses small currents to control high current operation. Therefore, it plays the role of automatic adjustment, safety protection and conversion circuit in the circuit. Relay: An automatic switch that essentially controls a large current with a small current. It has functions and functions such as automatic adjustment circuit, safety protection circuit and conversion circuit. 　　In the process of applying relays, the problems that arise are numerous. So as a  Power Relay Manufacturer   today, I mainly talk about a problem when using relays: Why are relays often disconnected? Here are the reasons why I sorted them out. Power Relay 　　1. The load current is greater than the rated switching current of the SSR, which will permanently short the re
