FAQs
The 85100A898S50 is a straight square flange receptacle with a straight backshell adaptor and a 1/3 bayonet coupling, oriented N. It is delivered loaded with a socket (female) solder cup contact and is designed to mate with Souriau 851 series connectors. This setup supports streamlined field assembly and consistent mating alignment across multiple harness configurations.
It operates from -40 °C to 125 °C, providing reliable performance in extreme cold and hot environments. Cadmium plating and an aluminium shell contribute to corrosion resistance and EMI shielding, reducing maintenance intervals. For programs in aerospace, defense, or harsh industrial settings, this means fewer field failures and longer service intervals.
Yes. The connector is MIL-DTL-26482 SI qualified, a standard commonly required in aerospace and defense programs. Its high contact density, rugged aluminium shell, and environmental compliance (REACH) support mission-critical assemblies. The 98-contact configuration enables dense harness routing while maintaining signal integrity in demanding platforms.
Key standards include MIL-DTL-26482 with SI qualification, indicating suitability for high-reliability applications. Environmental considerations include REACH compliance and cadmium plating survivability. The combination ensures regulatory alignment for aerospace, defense, and certain industrial environments where exposure to chemicals and temperature extremes is a concern.
High-density 98-contact configurations reduce the number of separate connectors and simplify harness routing, which lowers assembly time and reduces risk of wiring mistakes. The durable aluminium shell with cadmium plating extends service life in harsh environments, decreasing maintenance frequency. Overall, you gain faster deployments, fewer field failures, and lower total cost of ownership over device lifecycles.
