The invention relates to a device and a method for determining the rotational angle of a rotatable element (12) in a non-contact manner, said device comprising at least one magnetoresistive sensor element (14) which emits at least one first signal (S<SUB>M,1</SUB>, S<SUB>M,2</SUB>) for determining a rotational angle (T) of the rotatable element (12) in a first region (A). The inventive device and method are characterised in that a plunger core (30) and a coil (31) move in relation to each other in the axial direction (R) of a shaft (20) according to the rotary movement of the shaft (20, 36), the coil (31) emitting another signal (SC) relating to the modification of the coil inductance (L), such that rotational angles (T) beyond the first region (A) can be clearly determined in association with the first signal (S<SUB>M,1</SUB>, S<SUB>M,2</SUB>). |
