Abstract
A hydraulic actuator with a sensor mounted on the actuator cylinder for determining the position of the actuator. The arrangement comprises a hydraulic actuator which includes a cylinder having a bore in which a piston is slidably mounted for movement along the cylinder to extend and retract the hydraulic actuator. The cylinder has a side wall and a cylinder aperture extending through the side wall. A wire actuated encoder is mounted on the external surface of the cylinder, which has a wire which extends through the cylinder aperture and is attached to the piston for determining a stroke position of the piston within the cylinder.
