Features: This is a normally close proximity switch sensor with 4mm 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.
