Abstract
A sensor for the detection of the direction of a magnetic field comprises one single magnetic field concentrator with a flat shape and at least a first horizontal Hall-effect element and a second horizontal Hall-effect element, whereby the Hall-effect elements are arranged in the area of the edge of the magnetic field concentrator. Within its environment, the magnetic field concentrator alters the course of the field lines of the magnetic field and, in particular, has the effect that the field lines which, in the absence of the magnetic field concentrator would run parallel to the surface of the Hall-effect elements penetrate the Hall-effect elements almost vertically to their surface. Instead of horizontal Hall-effect elements, vertical Hall-effect elements can also be used when they are arranged beside the magnetic field concentrator. The sensor is particularly suitable as an angle sensor.
