Abstract
The invention relates to an angle position sensor, for recording the angular position of a component which may rotate about a rotational axis, including a magnetic ring, fixed to the component coaxially to the rotation axis, magnetised perpendicularly to the rotation axis and surrounded on the outer circumference thereof by a ferromagnetic external screening ring. A magnetic sensor element is further provided, arranged radially and fixed within the magnetic ring. The rotating component is surrounded by an inner ferromagnetic screening ring, arranged coaxially to the rotation axis and approximately radially with relation to the outer screening ring, which is further surrounded by an inner magnetic ring. The inner screening ring and the inner magnetic ring are fixed to the rotating component and the magnetic sensor element is arranged in an annular gap, formed between the outer magnetic ring and the inner magnetic ring.
