Overview Resources

Core features

MIL-DTL-38999 Series III derived shells and inserts reduce costs and leverage proven reliability and availability.
A resettable release mechanism was developed based on a separation-nut design with over 40 years of flight heritage.

Natc - nasa specification ssq 21635

The SG3 Series of NATC connectors utilize space-rated materials to meet all of the requirements of NASA Specification SSQ 21635. Fifty-three standard contact patterns are available in MIL-DTL-38999 Series III shell sizes 9 to 25. Additional features include:

Power configurations based on MIL-DTL-5015 inserts in shell sizes 25L to 37.
-115°C to 200°C operating temperatures.
High speed data including MIL-STD-1553.
Custom capabilities include thermal and electrical deadfaces and special insert patterns and shell configurations.

Application-specific solutions include cryogenic connectors

Standard products and engineered-to-order solutions are available to meet a wide range of application-specific requirements:

Cryogenic applications including fuel monitoring.
Disconnects for deadfaced, EVA, high voltage, in flight, and vertical-launch applications.
End-to-end cable solutions including integrated gas and fluid fittings.
Low-imparted-shock, positive mate monitoring, and zero-separation-force connectors.

Interstage-raceway connectors

The depicted solution incorporates three isolated insert compartments for flight, ordinance, and instrumentation contact groups and is qualified for use on the Peacekeeper Missile.

A lanyard mechanical release is initiated by missile-stage separation. Connector separation is assisted by an ejector spring.

A center-screw thread facilitates mating and demating. A visual indicator confirms mating status..

Umbilical connectors and in-flight disconnects

A broad range of flight-proven technologies can be leveraged to quickly develop custom umbillical connectors and in-flight disconnects. Design options include:

Fully integrated connector-and-actuator solutions in mechanically and electrically initiated configurations.
Release redundancy facilitated by any combination of mechanical lanyard releases and/or electrical pin puller release mechanisms.
Anti-bind roll-off shells, 360-degree EMI protection, electrically and thermally deadfaced configurations, push-pull snap action couplings, and visual and tactile mating indicators.
Lanyard-release connectors available in custom, D38999 Series III, and D38999 Series IV form factors.
