Manufactured from Santoprene™ rubber, this bumper provides protection for the Kuka KRC-4 teach pendant if accidentally dropped. Santoprene™ is immune to water, most water-based cleaning agents as well as many industrial coolants and cutting fluids. The bumper is custom-molded to the teach pendant’s exterior shape, and features a "stretch-to-fit" installation (akin to a cell phone sleeve). Protective ridges are molded around rotary switches and e-stop buttons—but do not interfere with their operation. 6-axis mouse function is preserved. Access to deadman switches on the back of the smartPAD is unencumbered. Access to the USB port on the back of the smartPAD is also preserved. A stylus flap is molded into the bumper to prevent inadvertant loss of the Kuka stylus. The bumper is aggressively textured to maintain positive grip/feel in wet conditions or in the presence of lubricants/coolants. The frame is perforated throughout for weight-savings, and to reduce the surface tension and accumulation of fluids.
