Abstract
A rotation angle sensing device is provided, which comprises (i) a magnetic field source that is capable of being mechanically coupled to a rotatable shaft, wherein the shaft is rotatable around a rotation axis, wherein the magnetic field source provides a magnetization which is substantially parallel to the rotation axis and not rotationally symmetric to the rotation axis, wherein the magnet field source comprises or is a permanent magnet; and (ii) at least two magnetic field sensor elements arranged to detect the magnetic field of the magnetic field source, wherein the at least two magnetic field sensor elements are located out of shaft and are placed at the same radial distance from the rotation axis. Also, a method for sensing a rotational angle is suggested.
