Eaton 85100A83S50 Receptacle - MIL-DTL-26482 SI qualified
Part Number: 85100A83S50
Quick Summary
The Eaton Souriau 85100A83S50 Receptacle provides MIL-DTL-26482 SI qualified connectivity for harsh aerospace and industrial environments. Field wiring often suffers from connector incompatibility, corrosion, and misalignment, driving downtime and maintenance costs. This design uses an aluminium shell with cadmium plating and REACH compliance for durability and safer operation. With a compact 41 mm length and three contacts, it enables easy installation and reliable supply-chain compatibility. The straight backshell and N orientation support space-constrained assemblies, while the 1/3 bayonet coupling provides quick, vibration-resistant mating. Delivered with the connector, it offers fast deployment in new builds and spares pipelines.

MIL-DTL-26482 SI qualification and REACH compliance establish aerospace-grade reliability while meeting environmental regulations. This configuration reduces qualification cycles and supplier risk, enabling faster program approvals. The Souriau 85100A83S50 is ideal for rugged automation and defense equipment where consistent performance under vibration is non-negotiable. Feature three solder cup contacts with a socket (female) delivery, enabling straightforward wire termination and robust contact integrity in harsh environments. This arrangement supports reliable power and signal paths with minimal insertion force and lower contact resistance, simplifying field wiring and maintenance. Feature 1/3 Bayonet coupling provides fast, secure mating with excellent vibration resistance. The compact coupling reduces assembly time on crowded panels and ensures consistent electrical performance across multiple mating cycles. Feature cadmium plating on an aluminium shell delivers corrosion resistance with a lightweight profile. This combination extends service life in outdoor or hazardous plant settings while keeping weight down for easier handling and installation. Feature straight backshell and N orientation streamline installation in tight spaces and align with predetermined harness routing. Availability as a complete adaptor-backend assembly minimizes parts hunting and speeds up deployment in new builds. Feature wide operating temperature range from -40 to 125 °C supports operation across extreme environments, reducing the need for multiple part numbers. Combined with the 8-size aluminium shell and 41 mm length, it delivers a compact, durable I/O solution for aerospace and industrial automation.

FAQs
Begin by verifying panel cutout dimensions for a square flange receptacle. Align the 85100A83S50 with the panel, ensure the N orientation is correct, and mate using the 1/3 Bayonet coupling for a secure, vibration-resistant connection. Confirm that the contact delivery is loaded, then attach the straight backshell adaptor to complete the assembly and ensure proper cable routing.
MIL-DTL-26482 SI qualification indicates the receptacle meets stringent military/aerospace performance criteria under vibration, temperature cycling, and environmental exposure. This reduces qualification risk for programs, supports long-term field reliability, and aligns with rigorous system integration standards commonly required in defense and aerospace applications.
Yes. The 85100A83S50 is a 3-contact receptacle with socket (female) solder cup contacts. This arrangement simplifies terminations for mixed signal/power paths, provides robust mechanical retention, and supports reliable electrical performance in challenging environments on panel or harness assemblies.
The product operates from -40 °C to 125 °C, enabling use across extreme ambient conditions. It features an aluminium shell with cadmium plating for corrosion resistance and is REACH compliant, helping streamline regulatory documentation for industrial, aerospace, and defense deployments.
Choosing the 85100A83S50 offers higher uptime due to robust MIL-DTL-26482 SI qualification and reliable solder cup contacts in a compact footprint. The aluminium cadmium-plated shell reduces corrosion-related maintenance, while the 1/3 Bayonet coupling speeds mating/dismantling. Overall, less downtime, fewer spare-part variations, and quicker field service translate to lower lifecycle costs.
