FAQs
For panel installations, ensure a square flange receptacle fits the 12 shell size and 26.5 mm width with the 48 mm depth. Use the straight backshell adaptor to align the connector with the panel cutout and secure with compatible hardware. The 1/3 bayonet coupling requires minimal torque while delivering reliable retention, and the Y orientation helps correct mating alignment in tight spaces.
The connector provides eight solder cup contacts throughout eight cavities, configured as a socket (female) gender. It is designed to operate over a broad temperature range from -40 °C to 125 °C and uses cadmium plating on an aluminium shell to balance corrosion resistance with weight, making it suitable for demanding environments.
Yes. It carries MIL-DTL-26482 SI qualification and features a robust aluminium shell with cadmium plating, plus a 1/3 bayonet coupling that resists vibration. The square flange receptacle and straight adaptor support secure, reliable mating in aircraft and other vibration-intensive equipment, while REACH compliance helps address environmental and regulatory considerations.
This part is MIL-DTL-26482 SI qualified, offering military-style interconnect reliability. It also complies with REACH environmental standards for material safety. The combination supports regulatory acceptance in aerospace and defense programs and aligns with safety and environmental requirements typical for rugged industrial applications.
The eight-contact solder cup design and ready-to-install configuration reduce assembly and maintenance time, lowering downtime and labor costs. The MIL-DTL-26482 SI qualification and durable aluminium shell extend service life in harsh environments, delivering a favorable total cost of ownership through fewer field failures and simpler field replacements.
