Abstract:
An angle sensor comprising a magnet (4) for providing a magnetic field and a sensor element (1) responsive to a lateral component (8) of the magnetic field to produce a sensor signal (U.sub.S) indicative of the angular position (.alpha.) of a target object (6) which is rotatable about an axis of rotation (5), the magnet being supported on and rotatable with the target object (6); characterized in that the angle sensor further comprises:(i) a measuring element (2) which is arranged adjacent the axis of rotation and produces a direction signal (U.sub.R) indicative of the direction of an axial component (7) of the magnetic field which traverses the measuring element; and(ii) an evaluation circuit (9) for determining said angular position (.alpha.) of the target object (6) based on the sensor signal (U.sub.S) and the direction signal (U.sub.R).
