Zusammenfassung:	A hybrid position sensor for determining the position of a hybrid target includes a main transducer for obtaining a first signal indicative for a position of the hybrid target within a first range and with a first resolution using a first or second technology; a support transducer for obtaining a second signal indicative for the position of the hybrid target within a second range and with a second resolution using the second technology if the main transducer is using the first technology and vice versa, wherein the first range is smaller than the second and the first resolution is higher than the second, and wherein the first technology is magnet based and the second technology is an inductive technology; a combiner for combining the obtained first signal and second signal to determine the position of the hybrid target.
