Eaton 85100AC2039P50 Receptacle - MIL-DTL-26482 SI Qualified
Part Number: 85100AC2039P50
Quick Summary
Eaton Souriau 851 series MIL-DTL-26482 SI qualified is a square flange receptacle designed for harsh environments and high-reliability assemblies. Engineers frequently face mating failures, corrosion, or loosening in field conditions; this receptacle addresses those challenges with a robust aluminium shell and cadmium plating for enhanced durability. MIL-DTL-26482 SI qualification and REACH compliance provide critical regulatory confidence, while the 39-position layout delivers dense connectivity in constrained spaces. In practice, you gain repeatable mating performance, easier field maintenance, and long-term total cost of ownership reduction, with compatibility across straight adapter backshells and a N-oriented assembly for clean installation in panel-moused systems.

Feature → Business Impact → Application: Solder Cup contacts deliver secure, vibration-resistant connections, reducing intermittent faults in demanding environments and increasing mean time between failures for factory automation and aerospace ground-support equipment. Feature → Business Impact → Application: Cadmium plating enhances corrosion resistance and longevity, lowering maintenance cycles and replacement costs in humid or salt-spray conditions common in shipboard or outdoor installations. Feature → Business Impact → Application: Aluminium shell with size 20 and 53 mm length provides a lightweight yet rugged envelope, improving ease of handling during installation and facilitating tighter panel fits in control cabinets. Feature → Business Impact → Application: 1/3 bayonet coupling offers quick, reliable mate-ability with repeatable alignment, shortening assembly time on production lines and in field upgrades for military and industrial systems. Feature → Business Impact → Application: Straight backshell adaptor with N-direction orientation simplifies cable routing and minimizes-right-angle stress, improving serviceability in enclosure-dense installations like automated packaging or robotic cells. Feature → Business Impact → Application: 39 contacts at a compact 53 mm length enables high I/O density without board-level redesigns, supporting scalable control architectures and easier migration paths for legacy systems. Feature → Business Impact → Application: Delivered with connector and loaded contact delivery ensure ready-to-mate readiness, accelerating installation workflows and reducing project lead times in aerospace and defense programs. Feature → Business Impact → Application: Receptacle type, square flange mounting, and robust mounting options deliver EMI/RFI containment and structural stability, making it suitable for harsh factory floors and aircraft maintenance bays. Feature → Business Impact → Application: REACH compliance and MIL-DTL-26482 SI qualification provide regulatory alignment for procurement and risk management, helping engineers meet corporate governance and supplier assurance objectives.

FAQs
The 85100AC2039P50 is a square flange receptacle designed for MIL-DTL-26482 SI qualified mating interfaces, using a 1/3 bayonet coupling with solder cup contacts. Pair it with the corresponding Souriau 851 series plug and appropriate straight adaptor backshell to ensure proper alignment and environmental sealing.
Key specs include 39 contacts (pin/male solder cup), aluminium shell size 20, overall dimensions around 53 mm length with 36.9 mm width and height, cadmium plating, straight backshell orientation, and operating temperature from -40 °C to 125 °C. It is delivered loaded and ready for panel installation.
Yes. The 85100AC2039P50 is MIL-DTL-26482 SI qualified with cadmium plating and aluminium shell, providing rugged performance in aerospace, military, and harsh factory environments. The straight backshell adaptor, 39-position layout, and N orientation support reliable, compact integration in constrained enclosures.
The straight backshell adapter aligns with the N connector orientation, simplifying cable routing and reducing bending stress on solder cup contacts. It shortens assembly time and improves serviceability in panel-mounted installations, especially where space constraints demand precise alignment and dependable mating forces.
The part carries MIL-DTL-26482 SI qualification for rugged reliability and REACH compliance for environmental considerations. While not listing CE or IP ratings, the combination of SI qualification and REACH aligns with broad industrial and defense procurement standards and supports regulated supply-chain commissioning.
