FAQs
The 85100A2234SX50 is a square flange receptacle with an adaptor backshell and straight orientation. It features 34 solder cup contacts and a shell size 22 made from aluminium, cadmium-plated for corrosion resistance. Mounting typically uses the square flange pattern compatible with 34-contact harnesses and a 1/3 bayonet coupling for secure, vibration-tolerant mating in constrained spaces.
MIL-DTL-26482 SI qualification ensures the connector meets stringent military and aerospace interface standards, including mechanical integrity, environmental durability, and electrical performance under harsh conditions. This translates to improved reliability in vibration, temperature extremes, and EMI environments, reducing field failures and warranty costs while simplifying qualification for your programs.
Yes. With a straight backshell adaptor, 1/3 bayonet coupling, and a 34-contact solder cup configuration, the connector provides secure mating and resilient current paths under vibration. The aluminium shell with cadmium plating offers robust protection, while the -40 to 125 °C operating range supports demanding aerospace and rugged industrial automation scenarios.
Key specs include 34 contacts, layout 34, shell size 22, aluminium shell, cadmium plating, and 44 mm length by 40 mm height and width. The contact type is Solder Cup, backshell angle is Straight, connector orientation X, and the receptacle type is Square Flange Receptacle. Ensure the mating connector matches a 34-position layout and 1/3 bayonet coupling for proper fit.
The solder cup contacts enable straightforward inspection and rework, while the cadmium-plated aluminium shell provides durable protection with light weight. MIL-DTL-26482 SI qualification reduces re-qualification cycles, and REACH compliance helps simplify regulatory traceability. Together, these factors lower maintenance downtime, extend service intervals, and reduce total cost of ownership in both aerospace and industrial automation environments.
