Abstract: A sensor-bearing unit, comprising: a bearing including at least one non-rotating ring and at least one rotating ring movable in rotation around a rotation axis; an impulse ring and a sensor device for tracking the rotation of the rotating ring around the rotation axis. The impulse ring is fixed to the rotating ring. The sensor device is fixed to the non-rotating ring and includes a differential detection cell having a structural pitch. The differential detection cell is tilted and has an effective pitch different from the structural pitch. A mechanical system can such sensor-bearing unit.

Abstract: The instrumented joint system includes a pivot pin capable of connecting a first part and a moving second part that can pivot with respect to the first part, and a detection assembly for detecting rotation parameters of the second part and which is mounted inside a housing of the pivot pin, the said detection assembly including at least one rolling bearing equipped with an inner ring and with an outer ring, and a sleeve angularly connected to the outer ring. The detection assembly is further provided with a support angularly connected to the pivot pin and on which the inner ring of the bearing is mounted, and with a retaining means for retaining the support axially inside the housing.
