Abstract
An analog output Hall effect sensor provides a proportional output representative of the angular position of a rotary shift member in a transfer case, transmission or the like. The rotary shift member is driven by a bidirectional electric motor through a speed reducing gear train. A wheel having a single spiral bipolar (N-S) magnetic track rotates with the output of the gear train and the shift member. The analog output Hall effect sensor is proximate the spiral magnetic track and provides an analog (ramp) output proportional to the position of the rotary shift member relative to first and second end points.
