An angle sensor device includes first and second magnet tracks, a sensor component, and a control unit. The first and second magnet tracks are fixed to a rotatable object and are configured to generate a non-homogenous field. The rotatable object is configured to rotate about a rotation axis and the non-homogenous field has a smaller gradient of magnitude along a rotational direction than a perpendicular direction, which is perpendicular to the rotational direction. The sensor component is positioned off-axis and is configured to measure a magnetic field including the non-homogenous field and provide magnetic field measurements. The control unit is configured to determine angular information from the magnetic field measurements.
