Inductive proximity switches, also known as inductive proximity sensors or metal sensors, contain a high-frequency oscillation circuit, detection circuit, amplifier circuit, trigger circuit, and output circuit. 

When power is supplied to the switch, the oscillator in the high-frequency oscillation circuit generates an alternating electromagnetic field on the detection surface of the switch. When a metal object approaches this surface, eddy currents are induced within the metal, which absorb energy from the electromagnetic field. As a result, the oscillator is either weakened or stopped.

This change in the oscillator’s state is detected by the detection circuit and converted into a level signal. The signal is then amplified by the amplifier circuit and passed through the trigger circuit, which activates the output transistor circuit to produce a switching signal. This process allows the switch to detect the presence or absence of metal, thereby achieving the purpose of metal detection.
