The A850492918N06B is a straight, non-environmental backshell designed to provide effective cable strain relief for MIL-DTL-38999 Series I & II connectors. Constructed from aluminum alloy with an electroless nickel finish, it features a direct-coupling mechanism and is designated for accessory shell size 18. This model includes a size 06 clamp, accommodating a cable diameter range from 0.56 inches (14.27 mm) to 0.75 inches (19.05 mm), and has a maximum length of 3.03 inches (76.96 mm) as specified by its 'B' length code. As a non-environmental solution, it is a cost-effective choice for applications within controlled environments, such as inside-the-box systems, where sealing against moisture is not required but robust cable support is essential.
