Abstract
A magnetic position sensor consisting of a non-electroconductive, non-magnetic carrier on which a resistive layer is arranged, in addition to a pick-off layer which is located at a distance from the resistive layer and at least partially overlaps the same. The distance between the two layers is selected in such a way that contact is established between the two layers by a magnetic device that can be moved along the overlapping regions of the resistive layer and the pick-off layer. The pick-off layer is a film which consists of a ferromagnetic material and is electroconductive at least on one side. The pick-off layer is a film which consists of a ferromagnetic material and is electroconductive at least on one side.
