Abstract: A process for determining the total pitch deviation of a position sensor fitted with a magnetic disk and a magnetic detector, the magnetic disk comprising pairs of magnetic poles, the process includes recording, over one mechanical turn, an angular signal of the magnetic intensity measured by the magnetic detector as a function of the angle of rotation of the magnetic disk, determining zero-crossing positions based on the angular signal recorded and the number of zero-crossing position determined, determining the pole pair lengths based on the zero-crossing positions, and determining the total pitch deviation based on the pole pair lengths.

Abstract: A sensor unit for sensing the angular position of a rotating element with respect to a fixed element includes a target fastened to the rotating element and a given number of sensing cells. Each sensing cell is connected to a connection device adapted to provide power supply, transmit data delivered by the sensing cells and connect each sensing cell to the ground. The sensor unit provides an output connector for electrically connecting the sensor unit to a reception device, a power supply system and the ground, via a connection cable having at least two connection wires. The connector includes, for each wire of the connection cable, a connection pin having a clamp portion adapted to receive an end of the wire, and a plug portion adapted to make a pressing contact with the connection device.

Abstract: A sensor-bearing unit, adapted for implementation in an oil lubricated environment and comprising: a bearing including at least one rotating ring movable in rotation around a central axis, and a detection device for tracking the rotation of the rotating ring. The detection device is locked to the bearing and includes at least one target and at least one sensor associated with the target. At least one axial side of the bearing includes a passage opened along an axial direction parallel to the central axis and allowing an oil flow through the bearing. The detection device includes an air gap defined radially to the central axis between a maximum outer radius of the target and a minimum inner radius of the sensor.
