Small Size Industrial Proximity Switch With Multiple Protection Function
Working principle
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.
Zhongde Electric Co., Ltd is engaged in design and production of customized Inductive Proximity Switches to suit various geometrical sizes and harsh environmental conditions of high temperature and pressure.
