Dualok High Vibration D38999 Connectors
Contact:
Description:
Dualok is an enhanced anti-decoupling mechanism designed to perform under severe vibration environments – far exceeding the performance of MIL-DTL-38999 Series III plugs. The Dualok system is proven to mitigate the negative effects of high vibration operation by eliminating connector back-off and reducing conditions that can cause fretting corrosion. Dualok is compatible with all D38999 Series III receptacle interfaces and has been qualified to multiple customer specifications.
Features & Benefits:
Superior Electrical Performance:
The Dualok system eliminates back-off under shock and vibration which significantly improves electrical performance under lightning strike, Electro-magnetic pulse events, and overall EMI performance by minimizing the apertures between the plug and receptacle shell interfaces. Testing on D38999 Series III aluminum plugs with Dualok showed 75% less millivolt drop than mil-spec requirements.
Minimized Contact Fretting:
The pin-socket interface remains tight under mated conditions. Dualok yields more consistent integrity across the contacts and reduces friction-induced oxides formation.
Size and Weight Savings:
Lightweight, Hybrid Composite/Metal Design. Connector weight savings by utilizing Dualok composite coupling nut with a Stainless Steel or Aluminum connector (D38999 Series).
