Feature: High-density 39-contact layout enables compact interconnects, reducing harness length and panel footprint. Business impact: Lower installation time, simplified routing, and potential weight savings in dense system enclosures. Application: Avionics bays and industrial control panels where channel count is high but space is limited. Feature: 1/3 Bayonet coupling provides quick, secure mating with improved vibration resistance. Business impact: Faster field assembly and maintenance without compromising reliability. Application: Flight-critical equipment and heavy-duty automation gear subject to mechanical shock. Feature: Cadmium plating on the shell with an aluminium shell body offers corrosion protection and light weight. Business impact: Extended service intervals and lower lifecycle costs in corrosive or humid environments. Application: Marine, aerospace, and outdoor industrial installations. Feature: Solder Cup contacts (Socket/Female) delivered loaded for immediate use. Business impact: Streamlined assembly, fewer on-site steps, and reduced risk of mis-matched contacts. Application: Control cabinets and equipment where solder-terminations are preferred. Feature: Backshell adaptor and straight backshell with Z orientation simplify cable routing and mating in tight spaces. Business impact: Easier installation geometry and better harness organization. Application: Aerospace conduit runs and compact industrial machines. Feature: Temperature range −40 °C to 125 °C and REACH compliance provide robust performance under extreme conditions. Business impact: Regulatory compliance and predictable uptime for harsh-duty applications. Application: General MIL-spec interconnects in challenging environments, from factory floors to aircraft systems.

FAQs
The 85100A2039SZ50 is a MIL-DTL-26482 SI qualified square flange receptacle with 39 solder cup contacts and a 1/3 bayonet coupling. It aligns with standard MIL-DTL-26482 mating interfaces, supports Z orientation, and ships ready-to-mate with the supplied connector, reducing integration risk in MIL-spec assemblies.
This receptacle operates from −40 °C to 125 °C and is REACH compliant, providing reliability in extreme temperatures and regulatory peace of mind for supply chains and environmental standards on aerospace and industrial equipment.
Yes. The 1/3 bayonet coupling and robust aluminium shell, combined with cadmium plating, deliver strong mechanical integrity under vibration and shocks typical of aerospace and heavy industrial environments, ensuring mating stability and long-term reliability.
With the option delivered with connector, straight backshell, and Z orientation, installation is streamlined. The loaded solder cup contacts simplify field terminations, and the 39-contact layout supports dense interconnects in compact enclosures, reducing harness complexity.
MIL-DTL-26482 SI qualification signals proven performance under aerospace-grade conditions, while REACH compliance mitigates regulatory risk. The high-contact density, corrosion resistance, and reliable solder-term compatibility translate to lower maintenance costs, fewer field failures, and longer equipment uptime.
