Sensor for the detection of the direction of a magnetic field

Abstract

"SENSOR FOR DETECTION OF THE SENSE OF A MAGNETIC FIELD". A sensor for sense detection of a magnetic field comprises a single flat magnetic field concentrator (3) and at least one first horizontal Hall element (2.1) and a second horizontal Hall element (2.2), the Hall elements are arranged in the edge area (4) of the magnetic field concentrator (3). The magnetic field concentrator (3) alters in the field around it the behavior of the field lines (13), causing, in particular, that the field lines, which in the absence of the magnetic field concentrator (3) would pass from parallel to the surface (8) of the Hall elements (2.1, 2.2), pass through the Hall element (2.1, 2.2) almost vertically to their surface (8). Instead of horizontal Hall elements, vertical Hall elements can also be used if they are arranged next to the magnetic field concentrator. The sensor is especially suitable as an angular sensor.
