MIL-DTL-26482 SI qualification and cadmium plating deliver rugged reliability, ensuring compliance with demanding defense and aerospace standards while resisting corrosion in harsh environments. This combination reduces field maintenance and extends service life, making it well-suited for aircraft systems, military electronics, and heavy equipment where secure mating is essential. 32 solder cup contacts in a socket (female) configuration provide straightforward and robust termination, supporting reliable signal and power transfer even after repeated mating cycles. The 32-cavity layout allows efficient harness routing in compact packages, reducing assembly steps and inventory variance for OEMs and integrators. The 1/3 bayonet coupling with a straight backshell adaptor offers fast, repeatable mating with positive retention and aligned installation, improving line efficiency and field reparability. Aluminium shell size 18 delivers a compact footprint with a 51 mm length and 33.7 mm width/height, weighing 46.1 g for easier integration. Operating temperature from -40 °C to 125 °C and REACH compliance ensure performance and regulatory alignment across diverse environments.

FAQs
The 85100AC1832SW50 is a square flange receptacle designed for MIL-DTL-26482 interfaces and ships with a connector option. It features a straight backshell adaptor and a W orientation, enabling aligned mating on MIL-grade panel Mounts and ensuring reliable integration with compatible 32-circuit harnesses.
Key specs include 32 solder cup contacts in a loaded socket configuration, aluminium shell size 18, cadmium plating, operating temperature from -40 °C to 125 °C, and REACH compliance. These factors support high-reliability signaling and power transfer in harsh environments while meeting regulatory requirements.
Yes. The product is MIL-DTL-26482 SI qualified with a robust aluminium shell, cadmium plating, and a 32-position solder cup contact array, making it well-suited for aerospace subsystems, military electronics, and rugged defense or industrial equipment.
Installation benefits from the 1/3 bayonet coupling for quick mating and a straight backshell adaptor for straightforward alignment. Termination uses solder cup contacts, enabling reliable harness connections. Ensure correct panel cutout for shell size 18 and orient the connector to the W position to match the mating receptacle.
The combination of SI qualification, corrosion-resistant cadmium plating, and a durable aluminium shell reduces field failures and maintenance frequency. The 32-circuit density on a compact form factor lowers harness complexity and inventory, contributing to lower lifecycle costs and higher equipment uptime in mission-critical systems.
