DC6-36V 300mA NPN NO 3-wire 4mm Tubular Inductive Proximity Sensor Switch LJ12A3-4-Z-BX

A proximity sensor is a sensor able to detect the presence of nearby objects without any physical contact. A proximity sensor often emits an electromagnetic field or a beam of electromagnetic radiation, and looks for changes in the field or return signal. "Proximity Sensor" includes all sensors that perform non-contact detection in comparison to sensors, such as limit switches, that detect objects by physically contacting them. Proximity Sensors convert information on the movement or presence of an object into an electrical signal. CityTech BD

It is a component widely used in automatic control industry for detecting, controlling, and noncontact switching. When proximity switch is close to some target object, it will send out control signal. It's widely used in machine, paper making, light industry for limiting station, orientation taking count, speeding trial ect.  CityTech BD
