Amphenol Aerospace Dualok 38999 Series III Connectors feature a locking mechanism to ensure solid coupling and metal-to-metal bottoming in severe vibration environments. The connectors mate with standard D38999 receptacles and utilized standard D38999 inserts. Amphenol Dualok 38999 Series III Connectors are designed to withstand and stay mated under vibrations that exceed MIL-DTL-38999 levels. Also, the coupling mechanism does not "settle" under vibration levels exceeding MIL-DTL-38999. The Dualok connectors are available in steel, aluminum, composite, or aluminum bronze materials in sizes ranging from 7 to 25.
