US Patent 10094683 Magnetically actuated pressure sensitive suspension position sensor

An elongated pressure sensitive potentiometer is disposed alongside and generally parallel to a reciprocating suspension component, such as a shock absorber, and between a steel track and a rolling or static magnet. The track and contained potentiometer extend from a mount at or near the top of a cylinder of the shock absorber to a point beyond the magnet when the shock absorber is in an uncompressed state. The mount couples the track to the shaft, parallel to and spaced apart from the shaft. Magnet attraction of the track compresses the potentiometer between the track and magnet.
