An apparatus for sensing the angular velocity of a vehicle wheel includes a rotor disk, a mounting bracket for attachment to the inner wall of an axis housing, and an electromagnetic sensor. The disk is coupled to the axle shaft for rotation and is rotatably retained in a cavity formed in the bracket. A mounting tube is also formed in the mounting bracket for retaining the electromagnetic sensor in close proximity to a periphery of the disk which has a plurality of generally radially extending evenly spaced indicating means formed thereon. The cavity limits axial movement of the disk to maintain the air gap between the disk and the sensor. The disk can be coupled to the axle by a pair of rings and a tab and slot system to limit radial movement of the disk.
