FAQs
Begin by aligning the square flange receptacle with the panel cutout and mating backshell adaptor. Insert and rotate the 1/3 bayonet coupling until it locks, ensuring the N-oriented contacts align. Verify solder cup terminations are prepared, and complete wire or PCB connections before final fastening. This method reduces misalignment and speeds assembly.
The connector supports 25 contacts in a 25-cavity layout with solder cup contact types. The aluminum shell size 20 and cadmium plating offer durable, corrosion-resistant mating. Operating temperature ranges from -40 to 125 °C, making it suitable for extreme environments and demanding industrial applications.
Yes. With MIL-DTL-26482 SI qualification and REACH compliance, the part is designed for aerospace, defense, and automation environments. Its straight adaptor and 25-contact configuration support complex control systems, while the square flange receptacle format simplifies panel integration and maintenance in harsh operating conditions.
The primary standard is MIL-DTL-26482 with SI qualification, ensuring electrical and mechanical performance under military specifications. The product also supports REACH environmental compliance. This combination provides assurance for regulated programs and helps with documentation and audit readiness during procurement.
The cadmium-plated aluminium shell delivers strong corrosion resistance, reducing field failures and maintenance cycles. The solder cup contacts simplify termination, cutting assembly time. A compact 25-contact configuration minimizes panel real estate, while the robust backshell and bayonet coupling accelerate replacements, delivering lower total cost of ownership over the product lifecycle.
