Abstract

A wheel speed sensor assembly includes a sensor having a housing configured to be received within a bore in a mounting block such that the sensor is spaced from, and faces, an exciter ring and senses rotation of the exciter ring. The housing extends along a longitudinal axis and defines a key on a radially outer surface having first and second portions having different heights. The first portion is configured to be received within a first keyway that is formed in the mounting block and is in communication with the bore in the mounting block. A clamping sleeve is configured to secure the sensor within the bore in the mounting block. The clamping sleeve defines a bore configured to receive the housing of the sensor and a second keyway in communication with the bore in the clamping sleeve. The second portion of the key is received within the second keyway.
