Abstract
A rotary sensor arrangement is configured to be used with a rotatable magnetic source and comprises a first and a second pair of magnetic field sensors, each pair arranged symmetrically with respect to rotation axes and providing respective sensor values. An evaluation unit determines a first sum value corresponding to a sum of the sensor values of the first pair, and a second sum value corresponding to a sum of the sensor values of the second pair. The evaluation unit further determines a difference value corresponding to a difference between the first and the second sum value and compares the difference value or a value derived thereof to a threshold value. Based on the comparison result, it is determined whether a failure status of the sensor arrangement is present.
