Eaton 85100AC168SX50 Receptacle - MIL-DTL-26482 SI qualified
Part Number: 85100AC168SX50
Quick Summary
The Eaton 85100AC168SX50 MIL-DTL-26482 SI qualified square flange receptacle for rugged aerospace and industrial use. Engineers struggle with reliable connections amid vibration, temperature extremes, and corrosion risk in harsh environments. MIL-DTL-26482 SI qualification provides trusted performance, while REACH compliance reduces regulatory risk for global deployments. The aluminum shell with cadmium plating delivers corrosion resistance without excessive weight, extending service life in demanding applications. The connector supports 8 contacts in a compact 16-shell size, and its straight backshell with a 1/3 bayonet coupling streamlines panel installation. This combination delivers lower total cost of ownership through fewer field failures and faster repairs. Designed for compatibility with Souriau 851 series connectors and industrial automation panels, it supports efficient assembly and predictable maintenance.

FAQs
The 85100AC168SX50 is a Souriau 851 series square flange receptacle designed for MIL-DTL-26482 connections. It uses a 1/3 bayonet coupling and straight backshell, with eight solder cup contacts loaded for a secure, vibration-resistant join. It fits standard Souriau 851-series housings and related panel interfaces, making it a straightforward upgrade for existing MIL-spec assemblies.
Key specs include eight contacts in eight cavities, backshell adaptor, square flange receptacle, cadmium plating on an aluminium shell, and a shell size of 16. The product length is 51 mm with a width and height of 31.3 mm, and a weight of 33.9 g. It supports solder cup contact terminations and operates from -40 °C to 125 °C, suitable for harsh environments.
Yes. It is MIL-DTL-26482 SI qualified, which is a key aerospace connector standard, and it features a lightweight aluminium shell with cadmium plating for corrosion resistance. The 1/3 bayonet coupling provides reliable mating under vibration, while the -40 to 125 °C range covers typical aerospace thermal cycles. The design aligns with Souriau 851-series ecosystems, easing integration into aircraft and spacecraft systems.
The part is REACH compliant, supporting regulatory requirements for chemical safety in many global markets. It uses cadmium plating, which is common in high-reliability connectors, and the aluminium shell contributes to weight savings and corrosion resistance. For regulated deployments, verify bilateral country-specific restrictions and supplier declarations to ensure full compliance in your application.
Plan for a square flange panel cutout compatible with an eight-contact configuration, and prepare for a straight backshell with a 1/3 bayonet mating sequence. The adaptor-backed backshell simplifies routing, and solder cup terminations require standard PCB or harness soldering practices. Ensure proper alignment X orientation during mating to maintain seal and electrical integrity in rugged environments.
