The proximity sensor switch (hereinafter referred to as the proximity switch) is a device that can sense the proximity of an object to perform corresponding switching actions. An induction switch is a position switch that can be operated without mechanical contact with moving parts. When the object approaches the sensing surface of the switch to the operating distance, it does not require mechanical contact and any pressure to make the switch act, thereby driving AC or DC electrical appliances or providing control instructions to computer devices. Proximity switch is a switch type sensor (Touchless Switch), it has the characteristics of travel switch and micro switch, and has sensing performance, reliable action, stable performance, fast frequency response, long application life, and anti-interference ability. It is strong and has the characteristics of waterproof, shockproof, and corrosion resistance. Products are inductive, capacitive, Hall, AC, and DC.
Proximity infrared sensor switch is also called a no-touch exit switch, it is an ideal electronic switch sensor. When the metal detector is close to the sensing area of the switch, the switch can quickly issue electrical commands without contact, pressure, sparks, and accurately reflect the position and stroke of the motion mechanism. Even if it is used for general stroke control, its positioning accuracy and operation Frequency, service life, ease of installation and adjustment, and adaptability to harsh environments cannot be compared with general mechanical limit switches. In the automatic control system, it can be used as a limit, counting, positioning control, and automatic protection link. Proximity switches have the characteristics of long service life, reliable operation, high repeat positioning accuracy, no mechanical wear, no sparks, no noise, and strong anti-vibration ability. Therefore, so far, the application range of proximity switches has become increasingly widespread, and the speed of its own development and innovation is also extremely rapid.
