Manufactured from Santoprene™ rubber, this bumper provides protection for the Fanuc A05B-2490-series iPendant 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 iPendant’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. Access to deadman switches on the back of the iPendant is unencumbered. 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.
