It is a component widely used in automatic control industry for detecting, controlling, and noncontact switching. When proximity switch is to some object, it will send out control signal. As it is capacitive type proximity switch, detecting object is not limited to only conductor, also liquid and even powder things, like plastic, water, glass, oil, etc. It's widely used in machine, paper making, light industry for limiting station, orientation taking count, speeding trial .
