Abstract
The invention relates to a device and a method for determining the rotational angle of a rotatable element in a non-contact manner, the device including at least one magnetoresistive sensor element which emits at least one first signal for determining a rotational angle of the rotatable element in a first region. A plunger core and a coil move in relation to each other in the axial direction of a shaft according to the rotary movement of the shaft, the coil emitting another signal relating to the modification of the coil inductance, such that rotational angles beyond the first region can be clearly determined in association with the first signal.
