Proximity Switch

Proximity switch is a position switch that can be operated without mechanical direct contact with moving parts. When the object approaches the sensing surface of the switch to the action distance, it can make the switch operate without mechanical contact and exerting any pressure, thus driving direct current electrical appliances or providing control instructions to computer (plc) devices. The proximity switch is a kind of on-off sensor (i.e. contactless switch). It has the characteristics of travel switch and micro-switch, as well as sensing performance. It has reliable action, stable performance, fast frequency response, long application life, strong anti-interference ability, and has the characteristics of waterproof, shock proof and corrosion resistance. The products are inductance type, capacitance type, Hall type, AC and DC type.
