ABS plastic shell, LED indicator light, angular column type, 3 wire system. When proximity switch is close to some target object, it will send out control signal. Power supply inverted connecting protection, short circuit protection, non-contact detecting device.
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. When proximity switch is close to some target object, it will send out control signal.
Working Principle:
The proximity switch consists of three major components: an oscillator, a switch circuit, and an amplifier output circuit.
The oscillator generates an alternating magnetic field. When the metal target approaches this magnetic field and reaches the sensing distance, eddy currents are generated within the metal target, causing the oscillation to attenuate and eventually stopping. Oscillator oscillation and stop changes are processed by the post-amplifier circuit and converted into a switching signal to trigger the drive control device to achieve non-contact detection purposes.
The closer the target is to the sensor, the closer the target is to the sensor, the greater the damping in the coil; the greater the damping, the smaller the current of the sensor oscillator.
The current loss of the inductive proximity switch, as the distance from the metal target decreases And decrease.
Normally open (NO): In the normal state, the signal output line is in the disconnected state and no signal is output. When the object is sensed, it is closed and the signal is output.
Normally closed (NC): In the normal state, the signal output line is in the closed state, and the signal is output continuously. When the object is sensed, it is disconnected and the signal is closed.
