ABSTRACT:
A shock absorber include a cylinder, a piston rod coupled to the cylinder, and a piston coupled to the piston rod. The piston rod is magnetically encoded so that it includes a plurality of magnetic phase shifts. The phase shifts allow the position of the piston rod relative to the cylinder to be determined so that it can function as a displacement sensor.
