Working priciple inductive proximity switch
Inductive proximity switch is composed of three
parts:oscillator,switch circuit and magnified
output circuit.The oscillator will generate an alternating electric field.When hemetal object approaches this electric field and reaches the induction distance, whirlpool will generate in metal object,
resulting in attenuation of vibrati on and then stop.The changeof
vibration and stop of oscillator is treated by begid stage
magnified circuit and convertedto switching sign,triggering driving
con-contact detection.
Current consumption of inductive proximity
switch decreases proportional to the metal object distance.
