FAQs
Mount the square flange on a compatible panel using the standard four-hole pattern, then mate with the corresponding plug. The straight backshell aids cable routing and alignment, while the 1/3 bayonet coupling provides a secure, quick-connect interface. Ensure solder cups are clean and seated before final mate and perform a continuity check after assembly.
MIL-DTL-26482 SI qualification confirms the connector meets stringent environmental and mechanical performance criteria, including vibration tolerance, temperature range, and mating reliability. This reduces risk in mission-critical systems and simplifies qualification processes for aerospace and other demanding programs.
Yes. The design supports harsh environments common to aerospace and industrial automation, with an operating range from -40 °C to 125 °C, an aluminium shell, and cadmium plating for corrosion protection. The square flange interface, straight backshell, and bayonet coupling provide robust, vibration-resistant connections suitable for rugged panels and automated equipment.
The product carries MIL-DTL-26482 SI qualification and REACH compliance, underscoring regulatory alignment and chemical safety. Be mindful of regional cadmium plating restrictions; verify local requirements and consider alternative finishes if necessary for specific programs or markets.
The rugged construction reduces maintenance downtime by maintaining secure connections under vibration and temperature swings, delivering predictable performance and longer service intervals. Although the upfront cost is higher, durability and reduced field failures lower total cost of ownership through less rework and shorter downtime in critical production lines.
