  • Patent number: 4726282
    Abstract: A fixture cylinder is provided that permits the use of integrally mounted proximity switches with the same fixed probe lengths on both end caps without requiring the use of spacers. The cylinder includes a body in which a piston assembly is slideably mounted about a longitudinal piston axis in a bore in the body. The piston assembly has a piston head, piston rod and a pair of hubs of equal diameter on opposite sides of the piston head. First and second end caps are provided on opposite ends of the body. Each end cap has a plurality of outer edges and a generally flat mounting surface is provided on one edge thereof for receiving a proximity switch. An aperture perpendicularly extends through each end cap and communicates with the bore in the body of the piston assembly. Two substantially identical proximity switches having generally flat mounting surfaces and the same fixed probe lengths are employed.
