Abstract
A sensor assembly includes a magnetic track having a plurality of magnetic poles separated by a plurality of pole junctions. The sensor assembly also includes a first magnetic sensor disposed proximate a high-resolution portion of the magnetic track and a second magnetic sensor disposed proximate a reference portion of the magnetic track. The second magnetic sensor spans adjacent pole junctions in the magnetic track. Each of the adjacent pole junctions includes a high-resolution segment corresponding with the high-resolution portion of the magnetic track and a reference segment corresponding with the reference portion of the magnetic track. The reference segment of each pole junction is one of offset and aligned with the corresponding high-resolution segment in each pole junction.
