Electronic implement control

Cylinder position sensor apparatuses are useful for monitoring the location of a piston within a hydraulic cylinder. The present position sensor mounting apparatus includes a resilient tubular electrical insulator positioned in a bore of a housing and has a leg of a sensor element extending therethrough. The sensor element is fixedly retained relative to the housing in one embodiment by a bolt which squeezes the insulator radially inwardly to clamp against the leg of the sensor element. In another embodiment, an insert slidably engages a tapered portion of a bore and is urged radially inwardly to squeeze the insulator inwardly to clamp against the sensor element. Thus, the insulator serves the dual purpose of electrically insulating the sensor element from the housing and the hydraulic cylinder while being utilized to clamp against the sensor element for retaining the sensor element within the housing.
