Product details
The TXR21AC90-0804BI from TE Connectivity Aerospace, Defense and Marine 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, Heat Shrink Adapter configurations, this design maintains stable RF performance through 100kRad(Si) total ionizing dose exposure, with <0.1dB insertion loss variation.With 0.711" (18.05mm) dimensions optimized for satellite payload constraints, the connector achieves 70% mass savings versus traditional space-grade components.The 8 interface incorporates redundant contact systems that maintain <5m resistance after 500 thermal cycles in vacuum conditions.Featuring 7/16-28 UNEF captive threading, the design prevents FOD (Foreign Object Debris) generation while enabling tool-less mating in space suit gloves.The 90° 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 Alloy, the housing provides exceptional resistance to atomic oxygen erosion (<0.1mm/year in LEO environment).The Electroless 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 Silver finish uses inorganic pigments that maintain reflectivity properties through extended UV exposure in space (tested to 15,000 ESH).Incorporating Tinel Lock, the design includes integrated passive intermodulation (PIM) suppression that maintains <-170dBc levels for sensitive transponder applications.
