The MIL-DTL-26482 SI qualified design provides a proven, industry-standard interface that improves compatibility across equipment and platforms, reducing integration risk and rework. This translates to shorter installation cycles and lower field labor costs, especially in aerospace and defense applications where reliable mating is critical. The 34 solder cup contacts offer high-density connectivity, enabling more signals or power within the same footprint and supporting tighter enclosure layouts—ideal for aircraft harnesses and rugged machinery. Cadmium plating on an aluminium shell delivers corrosion resistance in harsh environments, extending service life in salt air, humidity, and vibration-prone applications. The straight backshell and adaptor arrangement simplify panel mounting and accessibility during maintenance, while 1/3 bayonet coupling ensures quick, secure mating even in confined spaces. With a delivered-with-connector option and loaded contacts, technicians experience faster harness fabrication and test readiness, reducing downtime and accelerating integration programs. Finally, the 53 mm length and 40 mm width strike a balance between compact form factor and robust mechanical strength, supporting reliable operation across −40 °C to 125 °C and under dynamic loads common in aerospace and heavy industry.

FAQs
Yes. The 85100AC2234SW50 uses a 1/3 bayonet coupling and a straight backshell with adaptor options, designed for straightforward panel mounting and reliable mating in constrained spaces. It is a square flange receptacle compatible with 34-contact configurations and the delivered-with-connector option supports rapid field assembly.
The connector operates from -40 °C to 125 °C and uses solder cup contacts. It is a socket (female) contact arrangement with 34 positions, suitable for dense wiring harnesses in aerospace and rugged industrial environments.
Absolutely. It is MIL-DTL-26482 SI qualified, specifically designed for high-reliability aerospace and defense harnesses, as well as demanding industrial equipment. The combination of aluminium shell, cadmium plating, and high-contact-count supports mission-critical connections under vibration and environmental stress.
Cadmium plating is specified for enhanced corrosion resistance, while REACH compliance indicates alignment with environmental regulatory expectations. Users should verify local procurement and avionics or defense regulations, as cadmium finishes may be restricted in some jurisdictions or programs.
Key features include the delivered-with-connector option, loaded contacts, and a compact footprint (53 mm × 40 mm × 40 mm) with 34 contacts. These enable faster harness fabrication, easier testing, and quicker field maintenance, reducing downtime and overall lifecycle costs in mission-critical systems.
