Amphenol Interconnect India
Product details
The A8504952S44A 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 Cable Clamp configurations, this design maintains stable RF performance through 100kRad(Si) total ionizing dose exposure, with <0.1dB insertion loss variation.The 1.190" ~ 1.750" (30.23mm ~ 44.45mm) accepts phase-stable coaxial cables with <1 phase matching between connectors across -55 C to +125 C operational range.With 3.140" (79.76mm) dimensions optimized for satellite payload constraints, the connector achieves 70% mass savings versus traditional space-grade components.The 44 interface incorporates redundant contact systems that maintain <5m resistance after 500 thermal cycles in vacuum conditions.Featuring 2 3/4-16 UN 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 Alloy, the housing provides exceptional resistance to atomic oxygen erosion (<0.1mm/year in LEO environment).The Anodized process creates multi-layer surfaces that prevent cold welding in vacuum while maintaining <2 in surface roughness for consistent RF performance.The Black finish uses inorganic pigments that maintain reflectivity properties through extended UV exposure in space (tested to 15,000 ESH).Incorporating Clamp Screws, Self-Locking, the design includes integrated passive intermodulation (PIM) suppression that maintains <-170dBc levels for sensitive transponder applications.
