Abstract
A sensor for sensing angular movement of an object with a structure. Mounted on the structure are a stationary first portion and a second portion that is movable in rotation carrying respectively a first printed circuit and a second printed circuit centered on the axis of rotation and that face each other and that include conductive areas for forming capacitive sectors and, respectively, a primary excitation winding and a secondary excitation winding connected to the conductive areas of the second printed circuit; the first printed circuit being connected to an electronic control circuit arranged to create excitation signals that are transmitted by the first printed circuit to the second printed circuit by magnetic coupling, and to demodulate signals transmitted by the second printed circuit to the first printed circuit by capacitive coupling.
