MIL-DTL-26482 SI qualification anchors reliability for defense-grade and aerospace interfaces; combined with a 61-contact solder cup array, aluminium shell, and cadmium plating, it delivers high-density connectivity with reduced weight and robust corrosion protection. The 1/3 bayonet coupling enables quick, repeatable mating and strong vibration resistance, minimizing downtime in harsh environments. The square flange receptacle with straight adaptor streamlines panel mounting and cable routing, while the Y orientation supports efficient layout planning in multi-channel installations. Delivered with connector packaging reduces procurement steps and ensures mating integrity from the outset. These features translate to improved installation efficiency, predictable performance under temperature extremes (-40 °C to 125 °C), and lower lifecycle costs in demanding automation and control systems.

FAQs
The 85100AC2461SY50 is a square flange receptacle designed for panel mounting with a straight backshell and a cadmium-plated aluminium shell. It uses a 1/3 bayonet coupling, delivers 61 solder cup contacts, and comes with an adaptor as part of the assembly. The compact 53 mm length and 43.1 mm width/height support tight installations while maintaining ease of mating.
The connector operates from -40 °C to 125 °C, covering extreme cold to high-temperature environments common in aerospace and rugged industrial applications. Contacts are female socket solder-cup type, pre-loaded for reliable initial contact performance. The 61 contacts mounted in a 24-shell size with cadmium plating on an aluminium shell provide corrosion resistance and consistent electrical performance under vibration.
Yes. The 85100AC2461SY50 is MIL-DTL-26482 SI qualified, designed for high-reliability interfaces in aerospace, defense, and other harsh environments. The aluminium shell keeps weight down, while the square flange receptacle format simplifies panel mounting. Delivered with connector, it reduces assembly steps and ensures mating integrity in fielded systems.
This connector meets MIL-DTL-26482 SI qualification, supporting mil-spec interfaces, and adheres to REACH environmental compliance. Cadmium plating provides corrosion resistance in demanding environments, while aluminium construction reduces weight. These standards help with regulatory acceptance in defense, aerospace, and regulated industrial sectors, streamlining supplier qualification and lifecycle cost management.
Ensure proper mating alignment with the 1/3 bayonet coupling to avoid bent contacts during mating. Use the adaptor backshell to achieve correct IP-like sealing and vibration resistance. Crimp or solder the 61 solder cup contacts according to the applicable connector specification, and verify finish integrity of cadmium plating for corrosion protection during service life.
