An encoder for a wheel bearing includes a carrier plate ring and a magnetic encoding ring. The carrier plate ring has a radially running first leg, and an axially running second leg arranged on an outer ring or on an inner ring of the wheel bearing. The carrier plate ring has, on the radially running first leg, cut-outs distributed over its circumference. The first leg has a fold for forming a folded portion, and the folded portion at least partly covers the cut-outs. The carrier plate ring is at least partly surrounded by the magnetic encoding ring. The encoding ring has unipolar magnetization and at least partly comes into contact in the cut-outs.

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.
