Abstract:
An apparatus for detecting a rotation angle of a rotation around an axis of rotation, comprising:a transducer magnet for generating a magnetic field; a plurality of magnetic-field-sensitive sensor elements for detecting the magnetic field, with the transducer magnet and the plurality of magnetic-field-sensitive sensor elements being arranged such that, when rotating around the axis of rotation, the plurality of magnetic-field-sensitive sensor elements circles around the same relative to the transducer magnet, and wherein the plurality of magnetic-field-sensitive sensor elements define a scale, with the transducer magnet being arranged such that the generated magnetic field comprises a characteristic at a locus on the scale, and the locus on the scale uniquely depends on the rotary angle at least for a partial area of a full rotation, wherein the transducer magnet is magnetized inclined to the axis of rotation.
