Abstract

A sensor arrangement for redundant determination of an angle of rotation of a body about an axis of rotation includes at least one circuit carrier, a first sensor device having a first ECU and a second ECU. A magnet of the first sensor device and a coupling device of the second sensor device are each coupled in a rotationally fixed manner to the rotatable body. The first ECU is designed to receive signals caused by the rotational movement of the magnet and to generate at least one first electrical measurement signal which represents the current angle of rotation of the rotatable body. The second ECU is designed to receive signals caused by the rotary movement of the coupling device and to generate at least one redundant second electrical measurement signal which represents the current angle of rotation of the rotatable body.
