1、This is a normally open proximity switch sensor with 8mm detection distance. 2、When proximity switch is close to some target object, it will send out control signal.  3、It is a component widely used in automatic control industry for detecting, controlling, and non-contact switching.  4、High sensitivity, quick response, stable performance. 5、Non-contact detection avoids the sensor and the target object from damages. Features: This is a normally open proximity switch sensor with 8mm detection distance. When proximity switch is close to some target object, it will send out control signal. It is a component widely used in automatic control industry for detecting, controlling, and non-contact switching. High sensitivity, quick response, stable performance. Non-contact detection avoids the sensor and the target object from damages.
