1. A sensor device, comprising:
a magnetic field sensitive element to be positioned in a magnetic field of a magnet positioned on an end face of a shaft, the magnetic field sensitive element sensing an orientation angle of the magnetic field in a range between 0° and 360° and generating a sensing signal comprising a first sensing signal component and a second sensing signal component which have a 90° phase shift; and
electronic circuitry receiving and processing the sensing signal from the magnetic field sensitive element to generate an angle signal indicating an angular speed of the shaft and an absolute orientation angle of the shaft derived from the orientation angle of the magnetic field.
