Abstract:
1. A fluid pressure cylinder assembly for a work machine comprising a tubular cylinder, a piston rod assembly comprising a piston rod and a piston secured to the rod, the piston being slidably mounted on an interior of said tubular cylinder, a base connected to one end of the tubular cylinder, the base having a first bore formed therein in alignment with the piston rod and a second bore, the second bore being a cross bore in communication with the first bore, a sensor comprising a sensor sleeve and a sensor core mounted in the cylinder, said sensor sleeve being secured to the base and extending into a longitudinal bore in the piston rod, the sensor core carried by the piston rod in the piston rod bore and secured to the piston rod at an end of the bore remote from the piston, said sensor core slidably fitting on an interior of said sensor sleeve, a circuit board housing sealingly mounted in the first bore, said circuit board housing having an opening on a side thereof oriented to be aligned with the second bore, and a connector extending through the second bore in the base and having an end that extends through the opening on the side of the circuit board housing, said connector having contacts on an end that enters the circuit board housing to contact terminals on the circuit board in the circuit board housing.
