Abstract
The present invention relates to an inductive position sensor configured to determine a position of a target device. The inductive position sensor comprises at least two coils for determining the position. At least two of the at least two coils for determining the position at least partially overlap. At least one coil of the at least two at least partially overlapping coils is a transmitter coil and at least one of the at least two coils is a receiver coil. At least one of the at least two coils has N2+R portions substantially equally distributed over N substantially parallel planes, N being an integer larger than or equal to two and R an integer larger than or equal to zero. For each of the at least two coils the portions distributed over the N substantially parallel planes are substantially identical, so that mutual inductance between the at least two coils is substantially unaffected by misalignments between the N substantially parallel planes.
