In one embodiment, a sensor arrangement for the contactless sensing of angles of rotation on a rotating part includes a disk-shaped target coupled to the rotating part. The disc-shaped target has at least one metal surface and generates at least one piece of information for ascertaining the instantaneous angle of rotation of the rotating part in connection with a coil arrangement. The coil arrangement has at least one flat detection coil. The arrangement further includes at least one measuring circuit that converts the inductance of a corresponding at least one flat detection coil into a measuring signal. The inductance changes due to eddy-current effects, as a function of the degree of overlap with the at least one metal surface of the rotating target. The arrangement further includes an evaluation and control unit that detects the measuring signal using measurement techniques and evaluates the signal for calculating the angle of rotation.
