1. A sensor assembly for determining rotation about an axis and linear movement parallel to the axis, comprising:
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;
wherein the north pole and the south pole of the magnetic structure extend radially into a direction of the axis at an axial end of the sensor assembly; and
at least one sensor element sensitive to magnetic fields radially between the north pole and the south pole,
wherein the at least one sensor element is mounted to an elongated extension of a printed circuit board,
wherein the elongated extension protrudes from an open end of the magnetic structure and extends into a hollow interior of the magnetic structure, and
wherein the magnetic structure is rotatable about the axis and with respect to the at least one sensor element and linearly movable relative to the at least one sensor element and parallel to the axis.
