FAQs
Installation guidance starts with validating the panel cutout and ensuring proper alignment with the receptacle’s square flange. Use the one-third bayonet coupling to mate the connector firmly, then attach the straight backshell adaptor for streamlined routing. Confirm correct orientation (Z) during assembly to preserve contact reliability and EMI performance. This approach minimizes rework and supports consistent field results.
Key performance specs include six solder cup contacts with loaded contact delivery, a socket female contact type, and a square flange receptacle with aluminium shell. The connector uses cadmium plating for corrosion protection and supports a one-third bayonet coupling with a straight backshell for simple installation. It is designed to operate across a wide temperature range, supporting rugged environments.
Yes, the design targets harsh environments common in aerospace and rugged industrial settings. MIL-DTL-26482 SI qualification provides stringent structural and electrical reliability, while the aluminium shell offers strength-to-weight benefits. Cadmium plating adds corrosion resistance when permitted by environmental policies, and the backshell assembly supports reliable EMI performance in vibration-heavy applications.
Cadmium plating provides corrosion protection, but users should verify environmental compliance policies, particularly RoHS restrictions in some regions. Regular inspection for plating wear, mechanical damage, and fixture integrity is advised. Clean connections with approved agents and avoid abrasive handling to preserve surface protection and maintain consistent electrical contact quality over time.
Investing in MIL-DTL-26482 SI qualified connectors reduces field failures and rework, lowering downtime and maintenance costs. The solder cup contact design speeds assembly, while the durable aluminium housing and corrosion protection extend service life in demanding environments. Over a production cycle, these factors translate to lower total cost of ownership and improved system uptime.
