ABSTRACT:
A device for sensing the rotation speed of a bearing comprises an encoder member fastened to a rotating part of the bearing and a sensor assembly comprising a plastics material sensor support housing a sensor and a metal support for locating and fastening the sensor assembly on and to a non-rotating part of the bearing. The sensor support is overmolded onto the latter's outside surface. The sensor faces the encoder member in order to measure its rotation speed. The-metal support comprises a substantially axial centring portion adapted to cooperate removably with a bearing surface on the non-rotating part of the bearing and a washer-like plane radial portion adjacent the centring portion adapted to be clamped between a radial surface of the non-rotating part of the bearing and a radial surface of a non-rotating member. The device may be fitted to vehicle wheel hub assemblies.
