Overview
Inductive proximity sensors operate
under the electrical principle of inductance. An inductive proximity
sensor has four components; The coil, oscillator, detection circuit and
output circuit. The oscillator generates a fluctuating magnetic field
the shape of a doughnut around the winding of the coil that locates in
the device’s sensing face. When a metal object moves into the inductive
proximity sensor’s field of detection, Eddy circuits build up in the
metallic object, magnetically push back, and finally reduce the
Inductive sensor’s own oscillation field. The sensor’s detection circuit
monitors the oscillator’s strength and triggers an output from the
output circuitry when the oscillator becomes reduced to a sufficient
level.
