Single Arm Composite Backshells

SUNBANK Single Arm Composite Backshells are designed to mate with MIL-DTL-38999 I, II, III, and IV connectors and incorporate self-locking coupling. The self-locking feature of these SUNBANK backshells withstands high vibrations. Single Arm Backshells comprise lightweight, aerospace-grade composite materials up to 40% lighter than aluminum. The backshells are available with electroless nickel plating, meeting the requirements of AS85049 and RoHS/REACH compliance. A Ground Lug option allows soldering directly to the body.
