Angle sensor e.g. steering angle sensor, for motor vehicle, has spiral contour including guidance elements at initial area and/or end area, where guidance elements set back functional element on adjacent path of spiral contour

摘要

The sensor has a coded disk (2) that includes a multiplex spiral contour (3), through which a functional element (5) for determining speed of the rotor is guided. The spiral contour includes guidance elements at initial area and/or end area. The guidance element set back the functional element on the adjacent path of the spiral contour. The spiral contour forms a spiral nut, in which a section of the functional element is guided.
