1. A sensor arrangement for redundant determination of an angle of rotation of a rotatable body which is rotatable about an axis of rotation, said arrangement comprising:
at least one circuit carrier;
a first sensor device comprising:
a magnet rotationally fixedly coupled to the rotatable body; and
a first evaluation and control unit arranged on the at least one circuit carrier, the first evaluation and control unit configured to receive signals caused by the rotational movement of the magnet and to generate at least one first electrical measurement signal which represents a current angle of rotation of the rotatable body detect so as to detect the angle of rotation of the rotatable body based on a magnetic measuring principle; and
a second sensor device comprising:
a coupling device rotationally fixedly coupled to the rotatable body; and
a second evaluation and control unit arranged on the at least one circuit carrier, the second evaluation and control unit configured to receive signals caused by rotational 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 so as to detect the angle of rotation of the rotatable body based on an inductive measuring principle.
