Rotational position sensor, particularly applicable to determining steering wheel position in a motor vehicle over angles greater than 360 degrees has roller bearing with optical or magnetic coding
Roller bearing has an inner ring (1), an outer ring (2) and rollers (3) held between the rings by a bearing cage (4), with the cage having a rigidly attached scale element (5). An additional scale (6) is fixed to the inner or outer ring. The scales can have optical or magnetic coding that can be sensed using optical or magnetic sensors.
