1727655121

Optimized for satellite payload systems, Molex's 1727655121 redefines reliability standards in Rectangular Connectors - Contacts. Its radiation-hardened design ensures uninterrupted operation in geostationary orbit environments.The Stamped manufacturing process includes particle impact testing and TID radiation validation. Each lot is qualified per MIL-STD-883 Method 1019 for space applications.The Split Pin configuration incorporates redundant contact paths that mitigate single-event effects. This design feature is mandatory for space-qualified connectors experiencing cosmic radiation.Utilizing Crimp technology, the contacts maintain gas-tight seals in vacuum conditions. The cold-welded joints prevent outgassing while withstanding thermal cycling from -180 C to 150 C.Engineered for 22-24 AWG aerospace-grade wiring, the contact system prevents tin whisker growth in zero-gravity conditions. The special alloy composition meets ESA ECSS-Q-70-71 standards.The Tin employs gold-cobalt alloys that provide 100x better radiation resistance than conventional platings. This material selection is critical for maintaining contact resistance over 15-year missions.With space-qualified 98.4µin (2.50µm), the coating withstands atomic oxygen erosion while preventing fretting corrosion. This balance is essential for low-Earth orbit applications.
