E2K-C25ME1 1-25mm Capacitance Proximity Sensor Switch NPN NO DC 6-36V 300mA AC Voltmeter this is the chrome housedIt 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. As it is capacitive type proximity switch, its detecting object target is not limited to only conductor, but also liquid and even powder things, like plastic, water, glass, oil, etc. It's widely used in machine, paper making, light industry for limiting
