MIL-DTL-26482 SI qualification delivers proven reliability in vibration and temperature extremes, directly translating to fewer field failures and lower maintenance costs across aerospace, defense, and rugged automation applications. The cadmium plating on an aluminium shell provides a balance of corrosion resistance and lightweight strength, improving lifecycle performance in harsh environments where weight and reliability matter. The straight backshell and 1/3 bayonet coupling enable quick, tactile mating and secure retention, reducing assembly time and misalignment risk on crowded panels. With 61 contacts arranged in Layout 61 and a solder cup contact type, termination is straightforward, enabling repeatable performance and easier field repairs in complex harnesses. Delivered with connector and N orientation supports plug-and-play integration in existing data and power assemblies, while REACH compliance aligns with modern environmental standards. This combination supports predictable procurement, lower stock-keeping costs, and faster program onboarding in aerospace, defense, and industrial automation.

FAQs
The 85100AC2461S50 uses a square flange receptacle with a straight backshell and 1/3 bayonet coupling, designed for 61-contact layouts. Check your panel cut-outs for a 24-shell size and Layout 61 footprint, ensuring alignment with the N orientation and the included adaptor if required. It mates with Souriau 851 series connectors and matches common MIL-DTL-26482 configurations, simplifying upgrades or replacements.
This receptacle is rated for an operating temperature range of -40 °C to 125 °C, suitable for aerospace, defense, and harsh industrial environments. Cadmium plating on an aluminium shell provides corrosion resistance without excessive weight. With 61 solder cup contacts, you can expect reliable termination under vibration, helping maintain signal integrity in critical harnesses.
Yes. The Eaton Souriau 851 series is MIL-DTL-26482 SI qualified, which is a trusted standard in aerospace and defense interconnects. The REACH compliance supports regulatory requirements for environmental responsibility, and the 61-position, square flange receptacle design is tailored for rugged, high-performance assemblies common in avionics, military platforms, and mission-critical automation.
This part is MIL-DTL-26482 SI qualified and REACH compliant, ensuring suitability for regulated environments and import/export considerations. While the spec sheet emphasizes these standards, always verify program-specific requirements such as additional CE or IP ratings for your exact installation, as some programs may mandate broader certifications. The combination provided supports high-reliability, compliant integration.
The SI qualification and robust aluminium Cadmium-plated shell minimize field failures and corrosion-driven downtime, reducing maintenance cycles. The solder cup termination and 1/3 bayonet coupling speed mating and disassembly, shortening assembly and service times. Overall, you gain predictable lifecycle performance, faster repair turnarounds, and lower total cost of ownership in demanding aerospace, defense, and rugged automation programs.
