Based on the Anisotropic MagnetoResistive (AMR) effect, the KMI23/2 and the KMI23/4detect the rotational speed of target wheels. The KMI23/2 is used with active targetwheels (multipole encoders) and the KMI23/4 is used with passive target wheels(ferromagnetic gear wheels). This design delivers secure speed information over a widerange of speed, air gap and temperature. It delivers the speed information via a currentprotocol at the supply pins.
