Rotary position sensor that provides a linear output voltage proportional to absolute shaft rotation in either direction from a reference angle. Designed to convert rotary movement into a proportional voltage, these position transducers utilize conductive plastic technology on both the resistance and collector tracks.The transducer is not sensitive to either dirt or dampness. It is suitable for use with any of the termination methods currently in use. The use of an elastomer-damped precious metal multi-finger wiper ensures reliable contact even under the severest of working conditions. It applies to truck pedal position and cummins.
