A position sensor system includes a magnetic source and a sensor device movable relative to the magnetic source. The magnetic source has a first track of alternating magnetic poles, and a second track of an equal number of alternating poles, but 180° phase shifted relative to the first track. The sensor device is configured for measuring a plurality of magnetic field components, including a first magnetic field component at a first sensor location facing the first track, and a second magnetic field component oriented parallel to the first magnetic field component at a second sensor location facing the second track, and for deriving a first and a second difference signal from the plurality of magnetic field components, and for determining a position based on these difference signals.
