Abstract
A fluid pressure cylinder assembly has a sensor to provide a signal indicating the amount of extension of a piston rod from the cylinder. The sensor includes a sleeve that is fixed relative to a base of the cylinder and passes into a longitudinal bore in the piston rod, and the piston rod carries a sensor core that is in the bore and is secured to the piston rod at an end opposite from a piston on the rod. The core slides on the interior of the sensor sleeve. A connection is provided to the sensor sleeve such that as the core moves relative to the sensor sleeve a signal indicating the amount of movement and the relative position of the cylinder base and the piston rod is provided.
