product description 

Proximity switch is a position switch that can be operated without direct mechanical contact with moving parts. 

When the object approaches the sensing surface of the switch to the operating distance, no mechanical contact 

and any pressure can be applied to make the switch operate, thereby driving the DC electrical appliance or 

providing control instructions to the computer (plc) device.

Proximity switch is a switch type sensor (that is, contactless switch), it has the characteristics of stroke switch 

and micro-switch, and has sensing performance, and reliable action, stable performance, fast frequency response, 

long application life, strong anti-interference ability, and waterproof, shockproof, corrosion resistance and other 

characteristics. The Proximity switch is a position switch that can be operated without direct mechanical contact 

with moving parts. When the object approaches the sensing surface of the switch to the operating distance, no 

mechanical contact and any pressure can be applied to make the switch operate, thereby driving the DC electrical 

appliance or providing control instructions to the computer (plc) device.

The working principle of the proximity switch is the eddy current principle. When the measured object approaches 

the probe, once the distance between the two is less than a certain value, the proximity switch will act, the opening 

and closing state will change, and the proximity signal will be issued; When the measured object is far away from the 

probe, once the distance between the two is greater than a certain value, the proximity switch is activated again. The 

proximity switch does not require contact with the object under test and there is no risk of mechanical damage.
