Patent ID: 8866571

Claim:
A target support for supporting a target magnet within an enclosed proximity switch assembly, the target support comprising: a hub having a body portion that extends along a longitudinal axis, the body portion including an outer surface and a shaft aperture that extends along the longitudinal axis, the shaft aperture adapted to receive a portion of a shaft that extends along the longitudinal axis, wherein the body portion further includes one or more threaded body apertures that extend from the outer surface to the shaft aperture; a magnet support non-rotatably secured to the hub, the magnet support having a base portion that extends in a direction normal to the longitudinal axis, the base portion including a planar top surface, the magnet support further including a side wall that upwardly extends from the top surface of the base portion, the side wall being partially defined by an inner surface; one or more target magnets disposed on the top surface of the base portion of the magnet support between a portion of the hub and the inner surface of the side wall of the magnet support; a clamp plate having a planar bottom surface and a shaft aperture adapted to receive a portion of the shaft, the clamp plate being secured to the hub such that the bottom surface of the clamp plate is immediately adjacent to or in contact with a top surface of the hub and such that the bottom surface of the clamp plate is also immediately adjacent to or in contact with a top surface of the one or more target magnets; a set screw adapted to threadably engage one of the one or more body apertures such that a distal end of the set screw contacts an outer surface of the shaft to non-rotatably secure the target support to the shaft, wherein a minimum torque of 150 inch-ounces is applied to the set screw, and a high-temperature potting applied to one of a portion of the set screw or a portion of the one of the one or more body apertures to secure the set screw within the one of the one or more body apertures.
