Abstract
An angle sensor with a fixed stator and a rotor rotating about an axis of rotation in which the stator has optical sensor elements being aligned in a plane vertical to the axis of rotation on a circular line in the perimeter direction concentric to the axis of rotation and being distributed across a range of perimeter angle. The sensor sensor elements cooperate with the rotor coding. The angle sensor solves the technical problem of ensuring that mechanical tolerances will not adversely impact operation of the sensor. This problem is solved in that the longitudinal axes of the sensor elements are not aligned radial to the circle line on which these units are positioned in the perimeter direction, but rather are aligned parallel to each other.
