Abstract

Abstract A mounting arrangement for supporting a proximity sensing means such as a reed type proximity switch contiguous the outer peripheral surface of a fluid power cylinder, in which said fluid power cylinder is of the type comprising a cylinder body and a piston axially movable in said cylinder body, and in which said fluid power cylinder includes a pair of oppositely disposed end closure members respectively positioned at each of the respective opposite ends of said cylinder body and tie rod means connecting said oppositely disposed end closure members. The mounting arrangement comprises a sensing means support device adapted to be detachably mounted on the fluid power cylinder. The sensing means support device comprises a clamp member for detachable connection to the tie rod means, and a swivel member pivotally supported by the clamp member, the swivel member being positional in overlying relation to a portion of the outer peripheral surface of the cylinder body when the sensing means support device is mounted on the fluid power cylinder. The swivel member is adapted to support a sensing device, such as a reed switch, contiguous the outer peripheral surface of the cylinder body. The reed switch is responsive to the presence of a magnetic field; and the piston which is movable in the cylinder has a permanent magnet mounted thereon. The clamp member is provided with a notched contour adapted to fit over tie rods of different diameters, and is also provided with a hook profile which adapts the clamp member to be easily moved to any desired adjusted position along the tie rod and to be tightened into engagement with the tie rod and with the outer surface of the fluid cylinder.
