Working principle 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.
