Eaton 85100AC1210S50 Square Flange Receptacle - MIL-DTL-26482
Part Number: 85100AC1210S50
Quick Summary
Eaton 85100AC1210S50 is a square flange receptacle for high-reliability MIL-DTL-26482 connections in rugged equipment. Designers often struggle with secure mating, corrosion resistance, and regulatory compliance in harsh environments. MIL-DTL-26482 SI qualification and REACH environmental compliance are key certs here, while the aluminium shell with cadmium plating provides rugged protection without adding excessive weight. This combination supports fast assembly, reliable field performance, and long-term cost savings for aerospace, defense, and industrial automation projects. With compatible backshell adaptor options and a straight receptacle orientation, installation is streamlined, reducing harness complexity and downtime. Engineers can match 85100AC1210S50 to existing Souriau 851-series mating halves, enabling scalable, modular solutions across projects.

The 85100AC1210S50 is a MIL-DTL-26482 SI qualified square flange receptacle with 10 solder cup contacts. This arrangement ensures high-reliability mating for rugged equipment while maintaining a compact 48 mm length and 26.5 mm width. In practice, engineers gain consistent signal integrity and power delivery in aerospace, defense, and heavy industrial installations. Cadmium plating on an aluminium shell provides robust corrosion resistance and lightweight performance, ideal for service in temperature extremes and challenging environments. The cadmium finish also helps moisture seals and EMI shielding in dense harnesses, reducing maintenance cycles and replacement costs. The straight backshell with 1/3 bayonet coupling supports quick, tool-free mating and secure retention in tight spaces, while being delivered with connector options to simplify inventory. With 10 contacts and a 12-shell size, the footprint is optimized for compact harness routing and weight budgets. The N connector orientation and 10-position layout enable streamlined integration with Souriau 851-series mating halves across programs.

FAQs
The 85100AC1210S50 is part of the Souriau 851 series and is designed to mate with standard MIL-DTL-26482 series plugs and corresponding backshell accessories. Look for the 851-series mating halves and the straight/receptacle backshell options to ensure proper alignment and secure bayonet coupling. The N orientation further aids guided installation in tight harness spaces.
This receptacle supports an operating temperature range from -40 °C to 125 °C, enabling reliable operation in extreme environments such as aerospace enclosures and outdoor industrial equipment. This wide range helps maintain signal integrity and mechanical stability under thermal cycling, reducing the risk of contact degradation or connector creep during field service.
Yes. The MIL-DTL-26482 SI qualification indicates high-reliability mating under vibration and mechanical stress, while REACH compliance addresses environmental considerations. The aluminium shell with cadmium plating provides rugged protection and weight efficiency, making it well-suited for aerospace, defense, rail, and heavy industrial applications where durability matters.
This model is MIL-DTL-26482 SI qualified, ensuring mating reliability under vibrational loads. It is also REACH compliant, supporting regulatory requirements for environmental safety in many regions. Together, these certifications help manufacturers meet stringent industry standards and minimize risk across programs.
The 85100AC1210S50 supports durable, long-term performance with its cadmium-plated aluminium shell and robust solder cup contacts, reducing maintenance frequency. Quick 1/3 bayonet coupling and delivered-with-connector backshell options shorten assembly time. The result is lower total cost of ownership through fewer field failures, faster install times, and scalable compatibility across Souriau 851-series mating systems.
