A wheel speed sensor is adapted to be mounted entirely within the bored end of an axle. The sensor comprises a rotor, stator, permanent magnet and coil, all compactly mounted in a hermetically sealed housing. A retainer is provided within the axle bore for securing the sensor against rotational and axial movement relative to the bore. The rotor shaft which is mounted within the housing is provided with an extension which passes in sealed relationship through the housing and beyond the end of the axle. A connector arm is attached to the rotor shaft extension for engagement with the wheel hub cap.
