Product details
The 390MS077ZNU1411-12 from Glenair pioneers new capabilities in Circular Connectors - Backshells and Cable Clamps for satellite communications. This space-qualified solution combines radiation-hardened materials with exceptional signal integrity for LEO to GEO orbital applications.Certified for Backshell, Cable Clamp configurations, this design maintains stable RF performance through 100kRad(Si) total ionizing dose exposure, with <0.1dB insertion loss variation.The 0.640" ~ 0.734" (16.26mm ~ 18.64mm) accepts phase-stable coaxial cables with <1 phase matching between connectors across -55 C to +125 C operational range.With 1.137" (28.88mm) dimensions optimized for satellite payload constraints, the connector achieves 70% mass savings versus traditional space-grade components.The 14, 15, 16, 17, 18, 19 interface incorporates redundant contact systems that maintain <5m resistance after 500 thermal cycles in vacuum conditions.Featuring 15/16-20 UNEF-2B captive threading, the design prevents FOD (Foreign Object Debris) generation while enabling tool-less mating in space suit gloves.The 180° geometry minimizes outgassing potential (<1 10^-6 torr l/s/cm ) while withstanding 10^8 flex cycles in zero-G cable management systems.Constructed from Aluminum, the housing provides exceptional resistance to atomic oxygen erosion (<0.1mm/year in LEO environment).The Zinc Nickel process creates multi-layer surfaces that prevent cold welding in vacuum while maintaining <2 in surface roughness for consistent RF performance.The Shielded configuration provides >100dB EMI protection while maintaining <0.1% magnetic permeability for precision attitude control systems.The Black finish uses inorganic pigments that maintain reflectivity properties through extended UV exposure in space (tested to 15,000 ESH).Incorporating Clamp Screws, the design includes integrated passive intermodulation (PIM) suppression that maintains <-170dBc levels for sensitive transponder applications.Validated for Environment Resistant, the connector survives 100+ thermal vacuum cycles between -190 C and +150 C without seal failure.
