Device for detecting the rotational speed and/or the position of a rotating component

摘要

A device for detecting the rotational speed and/or the position of a rotating component, having at least one magnetic sensor element, which is securely connected to the rotating component, and a magnetic field sensor, which coacts with the sensor element and is designed to detect change in a magnetic field and is connected to an analyzing circuit. The magnetic field sensor includes at least one sensor element made of a sensor material exhibiting a CMR (colossal magneto resistance) effect.
