LJ series of proximity switches (also known as non-contact limit switch) is to close in on the action metal, widely used in the control of machine tools and other equipment.
Proximity switch consists of three parts: an oscillator, a switching circuit, output amplification circuit. The oscillator generates an alternating magnetic field. When the magnetic field near the metal target and the distance to an induced eddy current is generated in the metal target, resulting in attenuation of oscillation, as well as to stop vibration. Change oscillator stops oscillating and the rear-stage amplifying circuit is processed and converted into a switching signal to trigger the drive control means, so as to achieve the non-contact detection purposes. The closer the sensor target, the closer the sensor target, the greater the damping in the coil; greater damping, less current inductive proximity sensor oscillator switching current loss, and decreases with distance from the metal target. decreases.
Normally open type (NO) and normally closed difference (NC) of:
A normally open (NO) is a signal output line normal state OFF state, no signal is output, when an object is sensed when closed, the output signal.
Two, normally closed (NC) is a signal output line normal state to the closed state, a signal output continuously, only when the object is sensed OFF off signals.
