Rotational speed sensors
Rotational speed sensors are designed to determine the rotational frequencies of engines, automatic transmissions, transfer cases, electric motors, wheels of cars. The principle of operation is based on the Hall effect when the sensor’s sensor element interacts with a ferromagnetic gear.
The speed sensors are implemented with a current output and a voltage output.
