Product details
The L777HRDH78P from Amphenol ICC (Commercial Products) revolutionizes D-Sub, D-Shaped Connectors - Housings for satellite communications, designed to maintain signal integrity in extreme orbital environments. This space-grade D-Sub connector combines radiation hardness with outgassing performance for reliable LEO to GEO applications.Implementing D-Sub, High Density configuration, the connector achieves 70% mass reduction compared to traditional space connectors while meeting NASA STD-8739.4 requirements.The Plug for Male Contacts design features redundant contact systems that ensure continuous operation after 10^15 rad(Si) total ionizing dose exposure.With 78 available circuits, the design supports high-speed data buses (up to 12Gbps) alongside power distribution for satellite payloads.Optimized 4 row arrangement prevents multipaction effects up to 10^-6 Torr at RF power levels exceeding 100W.The 5 (DD, D) High Density incorporates thermal control surfaces that maintain stable temperatures during eclipse transitions.Special Signal contacts employ platinum-group alloys that resist atomic oxygen erosion in LEO environments.Designed for Free Hanging (In-Line) installation, the connector features captive fasteners that prevent FOD in zero-gravity assembly conditions.The Board Side (4-40) includes integral thermal straps that provide 5W/K heat transfer capability for thermal management of high-power components.Incorporating Grounding Indents, the design implements non-magnetic components that prevent interference with attitude control systems.Utilizing Steel, Tin Plated, the housing demonstrates <0.1% total mass loss (TML) and <0.01% collected volatile condensable materials (CVCM) per ASTM E595.Precision 100µin (2.54µm) plating provides stable emissivity ( >0.85) for effective radiative cooling in vacuum.
