Inductive Proximity Sensor SN04-N NPN NO Normally Open Detection Switch with SN Bracket (Blue, 2 Pack)

An inductive proximity switch consists of high frequency oscillation, detection, amplification, triggering and output circuits. The oscillator generates an alternating magnetic field on the detecting surface. When there is a metal object close to its detecting surface, the eddy current generated in the metal absorbs the energy of the oscillator, which makes it weaken to stop oscillating. The oscillator oscillation and stop vibration of these two states is converted into an electrical signal through the detection, amplification and trigger output circuit. Normally open (NO) is the usual state of the signal output line is disconnected state, no signal output, when sensed to the object is closed, the output signal. Normally closed (NC) is the usual state of the signal output line for the closed state, continuous signal output, when the sense of the object is disconnected, close the signal. signal indicator, when sensing metal objects the light is on for normally open, the light is off for normally closed. The function of proximity switches (also known as non-contact travel switches) is to act when approaching metal, and are widely used in machine tools, metallurgy, chemical industry, light textile and printing industries, in the automatic control system can be used as limit, counting, positioning control and automatic protection link, etc..
