Eaton 85100A2039P50 Receptacle - MIL-DTL-26482 SI Qualified
Part Number: 85100A2039P50
Quick Summary
85100A2039P50 Receptacle is a MIL-DTL-26482 SI qualified square flange connector designed for demanding aerospace and defence applications. Engineers often struggle with non-conforming parts, difficult mating, and inadequate environmental performance that drives field failures. This Eaton Souriau 851 series receptacle combines cadmium plating, an aluminium shell, and a 1/3 bayonet coupling to deliver rugged reliability from -40 °C to 125 °C, even under vibration and harsh exposure. Delivered with a connector, this straight adaptor supports N orientation and male solder contacts for streamlined assembly. By aligning with REACH compliance and SI qualification, it helps ensure supplier conformity while enabling easier integration with existing harnesses. The result is improved lifecycle performance and predictable procurement for mission-critical systems.

Feature → Business Impact → Application: The 85100A2039P50 uses a square flange receptacle with a cadmium-plated aluminium shell, delivering excellent environmental protection and structural integrity in compact form factors. This translates to reduced field maintenance, longer service intervals, and lower total cost of ownership in aero-structural assemblies and rugged industrial machinery. Application-wise, the 39-pin arrangement supports dense signal and power distribution for avionics, industrial controls, and military equipment, enabling tighter panel layouts without sacrificing connectivity. Feature → Compatibility → Installation: 1/3 bayonet coupling and straight backshell simplify mating with compatible Souriau 851 series connectors and harnesses, cutting assembly time and minimizing misalignment risk in cramped enclosures. Feature → Compliance → Risk mitigation: With REACH compliance and MIL-DTL-26482 SI qualification, the receptacle meets stringent regulatory and performance standards, reducing supplier risk and accelerating certification processes. Feature → Performance → Reliability: Solder Cup contact type and pin male contacts optimize solderability and durability for high-vibration environments, improving joint reliability in aircraft, ground vehicles, and robotics. Feature → Durability → Lifecycle cost: Cadmium plating on an aluminium shell provides robust corrosion resistance and weight savings, supporting long-term operation in harsh climates and reducing replacement cycles in fielded systems.

FAQs
This receptacle uses a straight backshell and a 1/3 bayonet coupling, requiring compatible mate, panel cutouts sized for a 36.9 mm width/height and a 44 mm length profile. Ensure cadmium-plated aluminium shell integrity and proper torque on mounting screws to maintain gasket performance and alignment with the mating plug. Verify connector orientation is set to N and that solder cup contacts are clean before assembly.
The device provides 39 contacts with pin male solder cup contacts, rated for an operating range of -40 °C to 125 °C. Cadmium plating on an aluminium shell offers corrosion resistance, and the REACH environmental condition indicates compliance with modern chemical restrictions. The square flange receptacle is designed for rugged environments common in aerospace and defence hardware.
Yes. The 85100A2039P50 is part of the Souriau 851 series and is MIL-DTL-26482 SI qualified, which aligns with strict aerospace and defence requirements. Its 39-contact layout, bayonet coupling, and robust aluminium shell support reliable performance under vibration, thermal cycling, and mission-critical operating conditions.
This receptacle is MIL-DTL-26482 SI qualified and REACH compliant, addressing high-standard military specification and chemical exposure controls. When sourcing for regulated programs, confirm compatibility with your program’s environmental and supplier qualification requirements and ensure the connector mates with your existing Souriau 851 series ecosystem.
The solder cup contacts and closed aluminium housing provide durable mating and weather resistance, reducing field repair frequency and downtime. Its high-specification build supports longer service intervals, lower replacement costs, and improved uptime for critical systems, contributing to a favorable total cost of ownership in aerospace and industrial automation projects.
