Abstract
A circumferential type wheel speed sensor is axially fitted in removable fashion over a specially designed elastomer sleeve molded to the outside of a cylindrical casing wall. The sleeve also fills in and seals an array of slots cut through the wall, which cooperate with teeth on a flux ring to create a strong signal. The sensor can be removed for service without removing or creating exposing openings through the seal.
