An angle sensor unit for measuring a rotational angle of a rotational position of a steering shaft of a motor vehicle may include a multipole magnetic ring that has a number of pole pairs and can be connected in a torque-proof manner to the steering shaft, at least two magnetic field sensors that are assigned to the multipole magnetic ring, and an evaluation unit that is configured to determine a rotational angle on the basis of the signals of the at least two magnetic field sensors. The at least two magnetic field sensors may be offset in a circumferential direction on an outside of the multipole magnetic ring such that a magnetic field that originates from the multipole magnetic ring, in a region of the two magnetic field sensors, has an approximate equal absolute value with opposite signs.
