Abstract
A piston-cylinder assembly, in particular for pneumatic, hydraulic or mechatronic systems, includes a cylinder housing and a piston. The piston is coupled to a piston rod and disposed in the cylinder housing such that it can move along a longitudinal axis. A measuring device for detecting piston or piston rod position is provided inside the cylinder housing.
