coupling, are environmentally-sealed and operate across a wide temperature range.
These connectors were originally designed for military vehicles and are now use for
multiple applications throughout the Aerospace & Defense Industry.
38999-Style Series III Composite (KJB)
A lightweight standard circular connector for use in military and aerospace environments
with significant weight savings over aluminium-bodied D38999-Style. High density
layouts with up to 128 data connections and power contacts rated up to 23A.
Features a triple-start coupling with anti-decoupling ratchet for high vibration
applications, Cadmium and Electroless Nickel platings, 100 percent scoop-proof
contacts and rated to 1500 mating cycles.
