Abstract
A sensor arrangement (2) for determining a rotational angle of a shaft (4) which has at least one locking ring (12) arranged on the shaft (4), wherein a radius of an outer face (40) of the at least one locking ring (12) changes with a period of n φ/360°, and wherein the sensor arrangement (2) has at least one first fixedly installed magnetic sensor (32) which is assigned to the at least one locking ring (12) and, during a rotation of the shaft (4), senses a magnetic field which is influenced by the at least one locking ring (12), wherein n is an integer.

A sensor arrangement for determining a rotational angle of a shaft (4) which has at least one locking ring (12) arranged on the shaft (4), wherein a radius of an outer face (40) of the at least one locking ring (12) changes with a period of n φ/360°, and wherein the sensor arrangement (2) has at least one first fixedly installed magnetic sensor (32) which is assigned to the at least one locking ring (12) and, during a rotation of the shaft (4), senses a magnetic field (58) which is influenced by the at least one locking ring (12), wherein n is an integer.
A method for determining a rotational angle of a shaft (4), in which at least one locking ring (12) which is attached to the shaft (4) is used, wherein a radius of an outer face (40) of the at least one locking ring (12) changes with a period of n φ/360°, and wherein a magnetic field (58) which is influenced by the at least one locking ring (12) is sensed, where n is an integer.
