description The present fluid cylinder includes a cylinder body having a cylindrical internal cavity therein with a longitudinal axis therethrough, the internal cavity being adapted for disposition of a piston and rod assembly for axial movement therein. The cylinder includes a member such as an end cap enclosing an axial end of the internal cavity, the member having a sensor port or passage therethrough extending between an internal opening communicating with the internal cavity and an external opening. A sensor is disposed in the internal opening of the sensor port or passage, and a sensor electronics module is disposed therein between the sensor and the external opening. The sensor is operable for sensing an axial distance of the piston or the rod from a predetermined location when disposed in the internal cavity and outputting signals representative of the distance to the sensor electronics module which includes circuitry for retrieving the signals.
