Space Rated Connectors
Eaton's custom-solutions capabilities enable quick-turn development of cost-effective and reliable space-rated solutions that are reusable, serviceable, and upgradeable. One example of Eaton's track record of innovation is the umbilical connector array depicted to the left.
- 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.
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.
