FAQs
For correct installation, note that the unit is a square flange receptacle with a straight backshell adaptor and Y orientation. It is delivered with a connector and uses 34 solder-cup contacts in a 53 mm long, 40x40 mm shell. Plan for proper panel cutouts, mating alignment, and secure 1/3 bayonet locking to ensure reliable field performance.
Yes. The 85100AC2234SY50 is MIL-DTL-26482 SI qualified, ensuring military-grade interconnect performance under demanding conditions. It also aligns with REACH environmental requirements, supporting compliance in regulated programs and reducing supply-chain risk for defense and aerospace projects.
This receptacle excels in aerospace wiring harnesses, military equipment, and rugged industrial automation panels. Its high contact count (34), solder-cup contacts, and 1/3 bayonet coupling support dense wiring, secure mating, and quick field servicing in harsh environments, making it a strong choice for both airborne systems and heavy-duty automation.
The device features an aluminium shell with cadmium plating for corrosion resistance and lightweight robustness. It operates over a wide temperature range from -40 °C to 125 °C and is REACH compliant, ensuring reliability in extreme outdoor or factory conditions and aligning with stringent environmental standards.
The 1/3 Bayonet coupling provides secure, fast mating with reduced risk of misalignment during assembly. This improves installation speed in tight spaces and enhances field reliability by delivering consistent contact engagement, which is particularly valuable for high-density 34-contact configurations in aerospace and industrial environments.
