Humphrey's latest cylinders are designed to be shorter, lighter and thinner than those of equal bore and stroke. Their flat pistons make them up to 40 percent thinner, and they have a 35 percent shorter dead stroke due to the block type end cap, which needs no mounting brackets, making for zero stroke dimension. They are light enough to not burden either the actuator axis or the stand, even with a Y-Z axis. They last longer and leak less, using high-strength stainless-steel bands. Lead wires for embedded sensor switches can be drawn out from a single surface through a cap groove on the cylinders' sensor switch tracks. They come with NPT ports and mounting options such as a shock absorber and F-tube supports.
