ABSTRACT:
A device for contactless determination of a rotary angle has two bodies which are movable relative to one another, at least one sensor coil through which an alternating current flows and whose inductivity and alternating current resistance value changes due to a relative change of a size of regions of a first one of the bodies which regions are associated with the at least one coil and composed of a material selected from the group consisting of an electrically conductive material and ferromagnetic material, the first body being arranged with mechanical prestress relative to a second one of the bodies.
