Abstract
An angular position sensor system includes a two-pole magnet rotatable about a rotation axis; a magnetic sensor device having a plurality of horizontal Hall elements including at least a first, second and third horizontal Hall element located on a virtual circle having a centre located on the rotation axis. The Hall elements are spaced by multiples of 90. The magnetic sensor device has a processing unit connected to the horizontal Hall elements for obtaining a first, second and third signal, and for determining a first pairwise difference between the first and second sensor signal, and for determining a second pairwise difference between the second and third sensor signal, and for determining an angular position of the magnet relative to the sensor device based on a ratio of these pairwise differences.
