Abstract
A rotary angle sensor for a rotary member such as a motor vehicle wheel comprises an emitter, and a plurality of reflectors arranged in the form of flat surfaces on a circular-cylindrical surface of the rotary member or of a rotational portion which in operation rotates with the rotary member, light emitted by the emitter being reflected by the reflectors and received by a detector. The detector produces corresponding signals which are evaluated in an evaluation arrangement for detection of the rotational angle involved.
