Small Size NO Proximity Sensor Compact Structure Long Service Life Easy Operation
Description
A normally open proximity switch is a position switch that can be
operated without mechanical direct contact with moving parts, when
the object approaches the sensing surface of the switch to the
operating distance. It is widely used in machine tools, metallurgy,
chemical, textile and printing industries.

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.
