MIL-DTL-26482 SI qualification provides military-grade reliability for demanding environments, translating to fewer field failures and lower maintenance costs in aerospace and industrial applications. The square flange receptacle design, 1/3 bayonet coupling, and straight backshell adaptor enable fast mating and straightforward installation in tight panels, reducing assembly time. A 3-contact, solder cup configuration supports robust signal integrity for critical sensors and control lines, while the adjacent 3-cavity layout helps consolidate wiring without sacrificing performance. Cadmium plating on an aluminum shell delivers corrosion resistance and lighter weight, contributing to improved thermal handling and fuel/energy efficiency in aerospace and rail systems. Delivered with connector and oriented to N, this solution simplifies inventory and sourcing in procurement workflows. The REACH-compliant finish and Souriau 851 lineage promote consistent compatibility with existing fleets and modules.
