Abstract
A differential type sensing unit which includes a winding core having a winding shaft is described. In one embodiment, a post extends from the winding shaft and is located intermediate first and second winding ends of the winding shaft. The post facilitates reversing the winding direction of a conductor wound on the winding shaft. The conductor is wound such that the sensing unit includes a first sensing coil and a second sensing coil formed in a series opposing configuration. The sensing unit may be integrated with a driving unit to include driving coils formed over the top of the sensing coils.
