Abstract
A high resolution encoder having a relatively high number of magnetic pole pairs with a magnetic flux strength sufficient for use in high resolution applications. Magnetic pole pair spacing varies from about 0.01 inch to about 0.1 inch with each magnetic pole pair having a magnetic flux in the range of about 2 gauss to about 700 gauss at a distance of 0.036 inch at a temperature of +20 degrees centigrade. This high resolution encoder is especially well-suited for use with magnetically encoded targets in sensor bearings.
