Series ultra-short case proximity sensor

A proximity switch is a type of position switch that can be operated without mechanical direct contact with the moving part. When an object approaches the induction surface of the switch to the operating distance, the switch can operate without mechanical contact or applying any pressure, thereby driving a DC electrical appliance or providing control commands to a computer (plc) device. A proximity switch is a type of switch-type sensor (that is, a contactless switch). It has the characteristics of both a travel switch and a microswitch, while also providing sensing performance. It operates reliably, has stable performance, fast frequency response, long life, strong anti-interference ability, and features such as being waterproof, shockproof, and corrosion resistant.

Ultra-short type proximity switch
Compact installation

 

Previous product		Ultra-short case type
Case length is too long, installation space is limited, direct wiring, inconvenient installation		Minimum length is only 17.6 mm, easy installation even in tight spaces, side exit wire model, space saving, convenient installation
Bottom illumination makes it difficult to confirm whether the operation state is stable due to the influence of mounting position and angle		Equipped with a high-brightness LED light, providing 360° illumination with no blind spots. The indicator is clearly visible, making the operation state easy to identify at a glance.
