Compact Structure Industrial Proximity Switch Directly Connected To PLC
Working principle
Industrial inductive proximity switch is composed of three parts: oscillator, switch circuit and magnified output circuit.
The oscillator will generate an alternating electric field.When metal object approaches this electric field and reaches the induction distance, whirlpool will generate in metal object, resulting in attenuation of vibration on and then stop.The change of vibration and stop of oscillator is treated by behind stage mag- nifide circuit and converted to switching sign, triggering driving control for non-contact detection.
