Abstract:
1. A magnetic angular-position sensor mounted between two carrier elements that are movable in rotation relative to each other about an axis of rotation, the sensor comprising: firstly a magnetic member defining a working zone in which there extends a magnetic field having field lines perpendicular to the axis of rotation; and secondly a detector member comprising at least one probe extending in the working zone of the magnetic member in order to provide a signal as a function of the angular orientation of the probe relative to the field lines in the working zone, wherein the magnetic member comprises two parallel bar magnet segments and two elongate pole pieces of ferromagnetic material extending perpendicularly to the bar magnet segments and covering the ends thereof, wherein the magnetic member is in the form of a frame so that field lines are parallel, and wherein the pole pieces have chamfered ends.
