Micro38999 Series
Miniature Circular Connectors
For harsh environments
Souriau Micro38999 Circular Connectors

Souriau introduces the Micro38999 Series Circular Connectors as a line of miniature scoop-proof connectors developed from MIL-DTL38999 . The Souriau Micro38999 Series Circular Connectors offer a space savings of up to 50% over the smallest MIL-DTL38999 Series III units. Designed as a harsh-environment solution that is both compact and versatile with the smallest shell sizes currently on the market, the integrated backshell enables the Micro38999 Series Circular Connector to be easily wired. The Micro38999 Series Circular Connectors are available in shell sizes 3, 5, and 7 with options of break-away push-pull ( 8BA ), threaded screw ( 8DA ), and bayonet ( 8LTA ) coupling .
