FAQs
The 85100AC2041P50 is designed as a MIL-DTL-26482 SI qualified square flange receptacle with 41 solder cup contacts, aligned for standard Souriau/Eaton mating interfaces. Its 1/3 bayonet coupling and N orientation ensure reliable engagement, while the straight backshell supports straightforward cable routing. This makes it highly compatible with existing MIL-DTL-26482 assemblies in aerospace and industrial equipment.
Installation benefits come from the adaptor backshell and square flange mounting, which simplify chassis integration and panel cutouts. The cadmium finish provides corrosion resistance, and the aluminium shell aids EMI/mechanical robustness. With 41 cavities and solder cup contacts preloaded, mating is predictable, and delivered-with-connector options reduce assembly steps on the shop floor.
Yes. The connector operates from -40 °C to 125 °C, covering a wide range of aerospace and rugged industrial conditions. The aluminium shell and cadmium plating offer durability against corrosion and wear, while the straight backshell and 1/3 bayonet coupling maintain mating integrity under vibration, making it a dependable choice for high-demand environments.
The 85100AC2041P50 is listed under REACH environmental compliance, ensuring responsible use of chemicals in production and end-use. While CE marking is not specified in the data, the MIL-DTL-26482 specification and REACH conformance provide assurance for European and global aerospace/industrial programs requiring robust interconnects.
Adopting the 41-position 85100AC2041P50 reduces wiring complexity and assembly time due to its high-contact density and delivery with connector options. The durable aluminium shell and cadmium finish lower maintenance and replacement costs in harsh environments, while the secure 1/3 bayonet coupling minimizes mating failures. Collectively, this yields lower downtime and better overall lifecycle value.
