Abstract:
1. A device for detecting a rotational angle of one of a steering wheel or a steering column of a vehicle, comprising: at least one magnet; at least one first sensor configured to detect the magnetic field of the magnet, and wherein the magnet and the first sensor are movably situated relative to one another; at least one housing, wherein at least one of the magnet and the first sensor is situated in the housing; at least one printed circuit board contacted in an electrically conductive manner by at least one connecting element of the first sensor, the printed circuit board having one of an interface or a connector plug; an evaluation unit situated at a distance from the housing, wherein one of an output signal of the first sensor or a signal derived from the output signal of the first sensor is relayed from the one of the interface or the connector plug of the printed circuit board to the evaluation unit, and wherein the evaluation unit is configured to ascertain the absolute position of the rotational angle of the one of the steering wheel or the steering column as a function of the output signal of the first sensor; and a second sensor configured to detect the magnetic field of the magnet, the second sensor being situated at a distance from the first sensor and outputting an output signal phase-shifted with respect to the output signal of the first sensor, wherein the at least one printed circuit board includes at least one linkage unit which gates the two output signals of the first and second sensors to form a gated output signal.
