Abstract

A sensor arrangement is provided. The sensor arrangement includes a rotatable shaft extending along a rotation axis; a magnet module coupled to the rotatable shaft configured to generate a magnetic field; and a sensing element configured to sense a rotating magnetic field caused by the magnet module upon rotation of the rotatable shaft around the rotation axis. The rotatable shaft includes a bore extending within a shaft end portion along the rotation axis. The magnet module is coupled to at least one face of the bore and configured to generate the magnetic field within the bore. The sensing element has a sensitive spot, the sensitive spot being arranged within the bore and exposed to the rotating magnetic field.
