Working Principle

The electronic proximity switch contains high-frequency oscillation circuit, detection circuit, amplifier circuit, the solution circuit and the output circuit. When the power is supplied to the switch, the oscillator in the high frequency oscillation circuit generates an alternating electromagnetic field on the detection surface of the switch. When there is a metal close to the switch detection surface, the eddy current inside the metal absorbs the energy of the alternating electromagnetic field in the oscillator. The oscillator is weakened or stopped. Oscillator energy changes in the two states, the detection circuit is converted to a level signal, through the amplifier circuit to amplify the level signal after the trigger circuit to trigger the output transistor transistor circuit to produce a switch signal. Thereby detecting the presence or absence of the metal. To achieve the purpose of metal detection.

About maintenance and overhaul

In order to keep the proximity sensor to work stably for longtime, the following regular examinations should be performed just like general control

1. Check the installation position of detected object and proximity sensor if any deviation,loosening or deformation exists.

2. Check the attached wires and connecting parts if any loosening,bad contact or wire breaking off exists.

3. Check if there is any metallic powder accumulation or not.

4. Check if the temperature condition and surrounding environment condition are normal or not.
