Abstract: An actuator arrangement includes a body and at least one of a piston assembly and a rod assembly slideably disposed in the body. A sensor arrangement includes a sensor, a sensor electronics module, and an interactive element. The interactive element is moveable relative to the sensor, wherein a position of the interactive element indicative of a position of the at least one of a piston assembly and a rod assembly is communicated to the sensor electronics module through the sensor. A housing assembly is attached to an end of the body and includes a sensor pilot portion. The sensor pilot portion in the housing assembly is structured and arranged to sealably receive the sensor electronics module therein, wherein the sensor electronics module is encased within the housing.

Abstract: 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.
