Product details
The 340107702B MDMA31S-FO from C&K Connect 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-Type, Micro-D configuration, the connector achieves 70% mass reduction compared to traditional space connectors while meeting NASA STD-8739.4 requirements.The Receptacle for Female Contacts design features redundant contact systems that ensure continuous operation after 10^15 rad(Si) total ionizing dose exposure.With 31 available circuits, the design supports high-speed data buses (up to 12Gbps) alongside power distribution for satellite payloads.Optimized 2 row arrangement prevents multipaction effects up to 10^-6 Torr at RF power levels exceeding 100W.The 0.050 Pitch x 0.043 Row to Row 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 Housing/Shell (Unthreaded) includes integral thermal straps that provide 5W/K heat transfer capability for thermal management of high-power components.Incorporating Dust Cap, the design implements non-magnetic components that prevent interference with attitude control systems.Utilizing Aluminum Alloy, Gold Plated, the housing demonstrates <0.1% total mass loss (TML) and <0.01% collected volatile condensable materials (CVCM) per ASTM E595.Precision 28µin (0.70µm) plating provides stable emissivity ( >0.85) for effective radiative cooling in vacuum.
