Eaton 85100E124S50 Receptacle - MIL-DTL-26482 SI Qualified
Part Number: 85100E124S50
Quick Summary
Eaton 85100E124S50 is a square flange receptacle for MIL-DTL-26482 connections in harsh environments. Engineers often struggle with ensuring reliable mating, corrosion resistance, and quick field assembly in compact installations. This connector series delivers MIL-DTL-26482 SI qualification and REACH compliance, with cadmium plating and a rugged aluminium shell designed to withstand demanding applications. By leveraging backnut mounting, a straight backshell, and a 1/3 bayonet coupling, you gain secure connections that resist vibration and moisture ingress. The 4-cavity, solder cup contact arrangement simplifies termination and reduces assembly time, while the N connector orientation supports consistent panel layouts across equipment families. This translates to improved uptime and lower lifecycle costs for automation and aerospace programs.

MIL-DTL-26482 SI qualification paired with a 1/3 bayonet coupling delivers a robust, vibration-tolerant connection. This reduces field failures and maintenance costs by ensuring a consistent mating cycle, even after thermal cycling. Ideal for aerospace enclosures and rugged industrial controllers where standardization with MIL-rated hardware matters. Aluminium shell with cadmium plating provides excellent corrosion resistance while keeping weight low, extending service life in outdoor or humid environments and lowering replacement intervals for harsh environments such as outdoor automation kiosks and process plants. Backnut backshell and straight orientation simplify installation and panel routing, enabling faster assembly and fewer alignment errors in compact control panels. Solder Cup contacts across four cavities deliver reliable terminations, supporting stable signal integrity across temperature ranges for sensor networks and critical control loops. The operating range of -40 to 125 °C broadens applicability across aviation, automotive, and industrial automation, reducing the need for multiple part numbers and improving supply chain consistency.

FAQs
Begin by aligning the N-oriented square flange receptacle with the panel cutout. Insert the backnut from the exterior and tighten to secure the backshell. Attach the mating connector using the 1/3 bayonet coupling while verifying the solder cup terminations are fully seated. Ensure a proper seal and check for axial alignment to avoid bending the contacts during mating.
MIL-DTL-26482 SI qualification guarantees a defined, interoperable interface with MIL-grade hardware, ensuring reliability under vibration, temperature cycling, and environmental exposure. For systems in aerospace, defense, and rugged automation, this reduces integration risk and lifecycle costs by promoting consistency with other MIL-spec components.
Yes. The receptacle operates from -40 °C to 125 °C and uses aluminium shell with cadmium plating for corrosion resistance, making it well-suited for outdoor, automotive, and aerospace control systems that demand durability under extreme conditions.
It's ideal for aerospace enclosures, rugged industrial automation, and control panels requiring four solder cup terminations. The 1/3 bayonet coupling and backnut mounting simplify integration in compact spaces, while the N orientation ensures consistent panel layouts across related equipment.
The MIL-DTL-26482 SI qualified design reduces field failures and maintenance, shortening downtime and lowering lifecycle costs. The robust materials and reliable terminations minimize rework, while the standardized interface simplifies inventory management and improves uptime for critical automation and flight-ready systems.
