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.
