Abstract
A wheel speed sensor including an annular rotor fixed to a wheel for rotation therewith and having circumferentially distributed surface interruptions. A sensing device mounted near the rotor is fixed against rotation and includes a sensing portion opposable across an air gap to the surface interruptions of the rotor to produce a signal representing rotation of the surface interruptions past the sensing portion. The rotor and sensing portion are of complementary generally V-shaped cross section and are separated by a V-shaped air gap such that the output signal is substantially insensitive to relative motion between the rotor and sensing device in an axial plane of the rotor.
