Abstract

A sensor arrangement having a rotatable driving shaft extending along a rotation axis and comprising a bore extending from a first end face of the shaft along the rotation axis; a magnet arranged at least partially within the bore and coupled to the driving shaft, the magnet configured to generate a magnetic field within the bore; a sensor element arranged at least partially within the bore, and configured to sense a rotation of the magnetic field in response to rotation of the driving shaft; and a magneto-static shield arranged to surround the magnet and the sensor element, wherein the magneto-static shield is stationary with respect to the driving shaft.
