MIL-DTL-26482 SI qualification and the Souriau 851-series lineage establish a robust, MIL-spec interconnect foundation. This translates to improved reliability, fewer late-stage design changes, and lower lifecycle costs due to known mating tolerances and documented performance. Ideal applications include avionics, ruggedized communications, and military ground-support equipment where certification traceability matters. Cadmium plating combined with an aluminium shell yields superior corrosion resistance and mechanical robustness in harsh environments. The business impact is extended product life, reduced maintenance cycles, and lower spare-part spend for deployed systems, benefiting aerospace enclosures, naval systems, and field-ready assemblies exposed to humidity and salt spray. High-density 26-contact configuration enables more signal paths without increasing panel footprint, reducing wiring complexity and assembly time while improving harness clarity in control cabinets and vehicle electronics. The 1/3 bayonet coupling and straight backshell adaptor with Y orientation simplify installation and field servicing, enabling quick mating in confined spaces without compromising vibration resistance. Solder Cup contacts delivered with the connector streamline field terminations and maintenance, eliminating extra assembly steps and reducing downtime in defense and aviation environments. Operating temperature range from -40 °C to 125 °C provides consistent performance across extreme climate zones, while REACH-compliance supports regulatory acceptance in modern procurement programs. Overall, the design supports scalable interconnects, efficient assembly, and reliable performance in demanding aerospace and military systems.

FAQs
This receptacle is part of the Souriau 851 series and is designed to mate with compatible 851-series plug-and-backshell components. It features 26 solder-cup contacts, a cadmium finish, aluminium shell size 16, a straight backshell, and a 1/3 bayonet coupling with a Y orientation. Delivered with connector options simplify integration into existing harnesses and reduce assembly risk.
Key specs include 26 solder-cup contacts in a male pin configuration, aluminium shell size 16, cadmium plating, straight backshell, and 1/3 bayonet coupling with Y orientation. Operating temperature ranges from -40 °C to 125 °C, and the part is REACH compliant, supporting reliable performance in harsh environmental conditions.
Yes. The 85100AC1626PY50 is MIL-DTL-26482 SI qualified, designed for demanding aerospace and defense environments. Its 26-contact density, rugged aluminium shell, and corrosion-resistant cadmium finish, combined with compatible Souriau 851-series backplanes, support mission-critical avionics, communications, and vehicle systems where stringent specifications and traceability are required.
Consider the straight backshell adaptor and Y orientation for alignment in tight panel spaces. The 1/3 bayonet coupling allows quick mating and unmate operations, reducing maintenance time. Ensure the mating connector and harness are compatible with the 26-contact arrangement and that the solder-cup terminations are prepared per the field-termination guidelines to maintain reliability.
Cadmium plating offers robust corrosion resistance, extending service life in harsh environments and reducing maintenance cycles. However, programs should assess regulatory requirements and environmental considerations. The REACH compliance of this part helps address procurement and sustainability goals, while ensuring compatibility with modern sourcing policies and lifecycle cost management in defense and aerospace programs.
