China manufacturer of producing Proximity Sensor Dimeter 18mm
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 vibration and then stop.The change of vibration and stop of osdillator is treated by behind stage magnified circuit and converted to switching sign,triggering driving con-contact detection.
