Abstract:
An arrangement for detecting a movement of a body, in which the body (20′) is mounted in such a way that it can move in at least one direction and in which a magnet (200) is incorporated. Its poles are aligned substantially parallel to a primary plane. A detector system is furthermore provided that comprises at least four magnetic field sensors (10a to 10d) for the detection of a change in the magnetic field when the body (20′) moves. In addition, a further magnetic field sensor (11) is provided for generating a correction signal that depends on the magnetic field. An evaluation unit (20) is used to provide movement information relating to the body (20′) derived from signals from the four magnetic field sensors (10a to 10d) and the minimum of one further magnetic field sensor (11).
