RD25M0S50TC
Positronic
Product details
The RD25M0S50TC from Positronic 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 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 25 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 3 (DB, B) 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 Mating Side, Female Screwlock (4-40) includes integral thermal straps that provide 5W/K heat transfer capability for thermal management of high-power components.Utilizing Steel, Cadmium Plated, the housing demonstrates <0.1% total mass loss (TML) and <0.01% collected volatile condensable materials (CVCM) per ASTM E595.Meeting IP65/IP67 - Dust Tight, Water Resistant, Waterproof requirements, the connector survives 1000 thermal cycles (-190 C to +125 C) with <1 m dimensional change.
