Abstract
A method and system for orienting and calibrating a magnet for use with a speed sensor. A magnet can be mapped two or more planes thereof in order to locate the magnet accurately relative to one or more magnetoresistive elements maintained within a speed sensor housing. An optical location of the magnet with respect to the magnetoresistive element and the sensor housing can then be identified in response to mapping of the magnet. Thereafter, the magnet can be bonded to the speed sensor housing in order to implement a speed sensor thereof maintained by the speed sensor housing for use in speed detection operations.
