Abstract

Implementations relate to a sensor assembly for determining rotation about an axis and linear movement parallel to the axis. The sensor assembly comprises a magnetic structure comprising a north pole radially displaced from the axis and a south pole radially displaced from the axis and opposite to the north pole. The north pole and the south pole of the magnet extend radially into the direction of the axis at an axial end of the sensor assembly. The sensor assembly further comprises at least one sensor element sensitive to magnetic fields radially between the north pole and the south pole.
