Product details
The M85049/31S18Z from Amphenol Interconnect India 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, E Nut configurations, this design maintains stable RF performance through 100kRad(Si) total ionizing dose exposure, with <0.1dB insertion loss variation.With 1.240" (31.50mm) dimensions optimized for satellite payload constraints, the connector achieves 70% mass savings versus traditional space-grade components.The 18, 27 interface incorporates redundant contact systems that maintain <5m resistance after 500 thermal cycles in vacuum conditions.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 Alloy, the housing provides exceptional resistance to atomic oxygen erosion (<0.1mm/year in LEO environment).The Zinc Cobalt process creates multi-layer surfaces that prevent cold welding in vacuum while maintaining <2 in surface roughness for consistent RF performance.The Unshielded 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 Self Locking, the design includes integrated passive intermodulation (PIM) suppression that maintains <-170dBc levels for sensitive transponder applications.
