A sensor arrangement comprises a first, a second and a third magnetic field sensor that are arranged along a curved principal direction. A first combination means is connected to the first and second magnetic field sensors and a first channel signal can be derived from the signals of the first and second magnetic field sensors by the first combination means. A second combination means is connected to the first, second and third magnetic field sensors (SM1, SWM2, SM3. A second channel signal is derived by the second combination means from signals of the first, second and third magnetic field sensors. An evaluation unit that is connected to the first and second combination means is set up to derive an end position of a magnetic source movable relative to the sensor arrangement as a function of the first and second channel signals.
