Abstract
A magnet-based rotary angle sensor system for detecting a shaft rotation. The magnet-based rotary angle sensor system includes a rotatable excitation unit which is mounted to a shaft for rotation therewith, and a static sensor unit. The rotatable excitation unit includes at least one excitation magnet. The static sensor unit detects an excitation-magnetic field generated by the at least one excitation magnet. The static sensor unit includes a first Wiegand sensor module and a second Wiegand sensor module which are arranged in a cross-shaped manner and axially spaced from each other.
