signal indicator, when sensing metal objects the light is on for normally open, the light is off for normally closed. 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. 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. When proximity switch is close to some target object, it will send out control signal. It is widely used in machine, paper making, light industry for limiting station, orientation taking count, speeding trial ect. It is a component widely used in automatic control industry for detecting, controlling, and noncontact switching Shape: Cylindrical Diameter: 12mm Size: M12*1*60mm Weight: 46g Cable Length: 1.2M Shape: I Type Size: 73*19.5*2mm Weight: 16g Shape: L Type Size: 38+38*19.5*2mm Weight: 16g Mode: LJ12A3-4-Z/BX Output Type: NPN NO Wiring Method: Brown connect to Positive, Blue connect to Negative, Black connect to Load (signal output).
