"Right angle design allows for use in tight spaces where standard depth straight exit backshells cause clearance problems. Die cast zinc alloy construction is practically indestructible and offers maximum protection against harmful EMI/RFI. When used with shielded cable, a complete ground can be made between connector shells. Five grommets are provided to best fit cable diameter used. D-sub sizes available are DB9, DB15 and DB25. All assembly and standard mating hardware is provided, including easy to use thumbscrews. Quantity pricing available, please contact your L-com Sales Representative."
