Abstract: In a sensor arrangement for determining a rotation angle of a magnet about an axis of rotation, with a sensor for capturing a radial component and a tangential component of the measuring field of the magnet and for determining the rotation angle on the basis of an atan function, the sensor is mounted, at a radial distance from the axis of rotation, on a printed circuit board parallel to the axis of rotation and is offset by an axial distance. In a design method, an initial axial distance and radial distance are selected, the profile is determined, and the axial distance and/or the radial distance is/are iteratively optimized. A selector lever is coupled in terms of movement to the magnet of the sensor arrangement. The sensor arrangement is optimized and installed with the selector lever, and a compensation arrangement is adjusted.

Abstract: The invention relates to a sensor arrangement for determining a rotation angle of a diametrically magnetized magnet about a rotation axis relative to a main support, containing two sensors at different circumferential positions having a radial distance to the rotation axis in order to detect tangential and axial components of the measurement field of the magnet, and an evaluating unit for determining the rotation angle from the components based on an arctangent function. In a method for determining the rotation angle, the components are detected by the sensors and the rotation angle is determined therefrom based on an arctangent function.

Abstract: A rotary switch apparatus contains a rotary switch that has a moving operating element that contains a magnetic device for generating a magnetic field. The rotary switch apparatus also contains a Hall sensor device that is configured to generate a sensor signal representing a characteristic of the magnetic field, to determine a position signal using the sensor signal, which indicates a rotation position of the operating element about an actuation axis and a longitudinal position of the operating element along the actuation axis.

Abstract: A hydraulically damping mount contains a working chamber and a compensation chamber that are filled with a hydraulically damping liquid and are separated by an intermediate plate. The working chamber and the compensation chamber are interconnected by an overflow channel and a bypass channel that can be opened and closed by an actuator that can be electromagnetically actuated in the axial direction. Accordingly, the actuator is embodied as a sliding sleeve in the form of a hollow cylinder defining the bypass channel, and contains a radially protruding armature on its outer side. The armature is received in the compensation chamber. The armature co-operates with an electromagnetic coil received in the intermediate plate, and with a baffle plate for opening or closing the bypass channel. In this way, small regulating forces and a compact structure are produced.
