Abstract
The invention concerns an instrumented bearing (1) comprising an outer ring (2), an inner ring (4), at least a row of rolling elements (6) arranged between a raceway of the outer ring (2) and a raceway of the inner ring (4), an assembly detecting rotation parameters comprising a sensor unit (11) integral with the non-rotating ring and supporting a sensing element (14) and a rotating coding member (16) forming a rotating part with the rotating ring, the coding member comprising an active part moving in rotation in front of the sensing element, the sensing unit and the non-rotating ring forming a fixed part. The rotating part comprises indexing means external to the active part of the coding element and capable of positioning at an angle said rotating part relative to a reference of the fixed part in a position wherein the coder generates in the sensing element a reference signal.
