Detail about Inductive Proximity Sensor 

Inductive proximity switch by high frequency oscillation, rectification, amplification, trigger and output circuit. Oscillator in the detection of surface produces an alternating magnetic field when a metal objects close to the test surface, eddy current generated in metal absorbs the energy of the oscillator, make it less to stop. Vibration generator oscillation and stop of the two state into an electrical signal through the detection, enlarged trigger output circuit.
