Position Sensors play an important role in our daily lives. A position sensor, as the name indicates, provides feedback on the position of the measurand by detecting the presence/absence of an object ...

Sensors with a stainless-steel face use such low-frequency alternating fields that their detection area extends well through the metal face of the sensor to detect metallic objects on the other side.

When a metallic target comes close, the opposing eddy currents induced in the target cause a drop in voltage across the originating oscillator. A detector circuit (Schmitt trigger) and amplifier ...

1. Inductive sensing is a ratiometric scheme where the magnetic field of a single primary coil is sensed by a pair of secondary coils after the field has been “disturbed” by a nearby metal object.

Though sometimes dubbed a load-dump sensor, it does not detect dumped loads. The term load dump refers to special circuitry protecting the sensor from high-voltage spikes in the vehicle wiring ...
