ABSTRACT:
An inductive angle-of-rotation sensor, which is composed of a printed-circuit board, on which an excitation printed conductor and a receiving printed conductor are applied, the receiving printed conductor having a first partial section, which extends in a first plane, and a second partial section, which runs in a second plane. In addition, the inductive angle-of-rotation sensor has a graduation element, which is rotatable in relation to the printed-circuit board and includes a graduation track, which is composed of alternately arranged, electrically conductive and non-conductive graduation regions. The receiving printed conductor supplies an uneven number of signal periods within one rotation relatively to the graduation element. The first partial section of the receiving printed conductor is substantially greater in length than the second partial section. Moreover, a rotary transducer may be equipped with this angle-of-rotation sensor.
