Abstract: An apparatus is arranged for sensing a position of a target, in particular for offset invariant sensing of the position of the target is described, as well as the respective target and the method. The apparatus comprises at least two sensor elements. At least one sensor element of the at least two sensor elements generates a magnetic field. At least one other sensor element of the at least two sensor elements receives the magnetic field and outputs at least one signal associated with the received magnetic field. The target affects a coupling of a magnetic flux of the magnetic field between the at least one sensor element generating the magnetic field and the at least one other sensor element receiving the magnetic field and wherein the target is non-rotational invariant.

Abstract: A target configured to be used with a position sensor for sensing a position of the target is described. The target includes at least one elongated conductive loop structure for allowing eddy currents to flow therein and configured to affect a magnetic field received from the position sensor in a preferred direction along the at least one elongated conductive loop structure.

Abstract: A sensor package comprises a non-conductive substrate, at least two electrically conductive coils located at a first side of the non-conductive substrate, an evaluation circuit located at a second side of the non-conductive substrate opposing the first side of the non-conductive substrate and conductive connections between the at least two electrically conductive coils and the evaluation circuit.

Abstract: An apparatus for sensing a position of a target, in particular for offset invariant sensing of the position of the target, is described as well as a corresponding method. The apparatus comprises at least three sensor elements. At least one sensor element of the at least three sensor elements generates a first magnetic field. At least two sensor elements of the at least three sensor elements receive a second magnetic field associated with the first magnetic field. The at least two sensor elements of the at least three sensor elements form at least one sensor element pair and provide a signal indicative of the position of the target.
