Proximity switch working principle classification:
1. The inductive proximity switch belongs to a position sensor with switching output. It is composed of an LC high-frequency oscillator and an amplification processing circuit. When a metal object approaches the oscillating induction head that can generate an electromagnetic field, an eddy current is generated inside the object. . This eddy current reacts on the proximity switch, which attenuates the oscillation ability of the proximity switch, and changes the parameters of the internal circuit, thereby identifying whether there is a metal object approaching, and then controlling the switch to be on or off. The objects that this proximity switch can detect must be metal objects.
