Abstract
Encoder device for a sensor for detecting the rotational speed of a rotating member of a bearing 1 mounted on a non-rotating member of the said bearing 1, of the type comprising a sensor 7 secured to an element that is stationary with respect to the non-rotating member and past which an element forming a rotor rotates with a small air gap, which element is equipped with an encoder 8 capable of producing in the sensor 7 a periodic signal of frequency proportional to the rotational speed of the rotor element. The encoder 8 comprises an annular active part 14 made using a plasto-magnet and provided with an active region 16 arranged to travel past the sensor 7. The encoder 8 comprises a reinforcing part composed of two annular elements 15 arranged in contact with the active part 14, one on either side of the active region 16.
