ABSTRACT:
A seal with internal reinforcement is mountable on a stationary ring of a bearing, an insulating film with conductive tracks being fixed to the reinforcement. A sensor element, for sensing an encoder element carried by a rotating ring of the bearing, contacts the insulating film and the conductive tracks. Constitutive material of the seal covers at least a portion of the reinforcement and the insulating film and provides protection for the conductive tracks and sensor element. Connecting devices for passing wiring through the reinforcement are also described.
