Abstract: The invention relates to a method for determining the position that a magnet has at a time of measurement relative to a row of sensors, wherein a first sensor signal is generated by the first sensor, the value of which depends on the position of the magnet relative to the first sensor, and a second sensor signal is generated by the second sensor, the value of which, depends on the position of the magnet relative to the second sensor. First, the value that the first sensor signal has generated is compared with a first reference value. Second, the value that the second sensor signal has generated is compared with a second reference value. A relative value is formed from the value that the first sensor signal and the value that the second sensor signal. Third, this relative value is compared with a third reference value. From these three steps, the leading signal is chosen to determine the position of the magnet relative to the row of sensors.
