The invention relates to a magnetic sensor for determining the position of a part (2) that is, on the one hand, rotatably mobile following an angular course limited according to a rotary movement (R) and, on the other hand, translatably mobile according to an axis of translation (X) and following a limited linear course, said sensor comprising, on the one hand, a magnetised target (3), rigidly mounted onto the mobile part (2), in the form of a radially magnetised cylinder portion having an axis of symmetry matching the axis of translation (X) and, on the other hand, a system (5) for measuring the magnetic induction of the magnetised target in order to determine the position of the target in space. According to the invention, the system (5) measures, at a single point, the direction of magnetic induction in two orthogonal planes, one of which (P1) is normal to the rotary movement (R) and the other one of which (P2) is normal to the translation movement (X), in order to determine the position and orientation of the target. |
