Abstract
A passive magnetic position sensor is constructed of an electrically non-conductive, non-magnetic substrate on which a resistance layer and a soft-magnetic, electrically conductive bending-beam structure are arranged. The resistance layer and bending-beam structure are arranged at a constant distance apart partially overlapping each other. The distance apart is selected so that, under the action of a magnet device conducted along the overlapping region of the bending-beam structure and resistance layer, contact is produced between resistance layer and soft-magnetic bending-beam structure. In order to provide a position sensor which permits a precise tapping of voltage, the electrically conductively developed resistance layer has along its longitudinal direction a meander-like structure adjoined by taps which have contact surfaces on the regions opposite the soft-magnetic bending-beam structure.
