Abstract

An encoder is disclosed for measuring and/or coding linear or rotary motions wherein the distance of the air gap in the device varies as a function of the distance along the device. The device can be used for non-contact shift position sensing to reduce wear and to generate an analog signal for a driver control in a hostile environment.
