Functional principle

The inductive all-metal switches operate on

the basis of the electromagnetic pulse method.

Unlike standard inductive sensors, the magnetic

field is not generated through oscillation but

through short, periodic current pulses flowing

through the coil. The magnetic field induces

voltage in the object to be detected, which, for

its part creates a current flow in this object. After

switching off the current pulse, the current in

the object also drops, now inducing voltage

back in the emitter coil. This voltage is the

wanted signal and remains unaffected by

energy dissipation in the magnetic field. Only

non-ferromagnetic or poorly conductive metals

provide a low signal.
