Abstract
A system and method for determining a position and or speed of a rotating shaft includes a target wheel for securement to a rotatable shaft, the target wheel including a plurality of North/South pole pairs, each pole of each North/South pole pairs being essentially the same size; and a sensor assembly. The sensor assembly includes a first magnetic sensor array for sensing the pole pairs to provide a cosine signal and a sine signal and a second magnetic sensor array for sensing the pole pairs to provide a cosine signal and a sine signal, wherein the second magnetic sensor array is disposed transverse to the first magnetic sensor array. An electronic processor is configured to receive inputs from the first magnetic sensor array and the second magnetic sensor array, and to determine a position and/or speed of the shaft.
