MIL-DTL-26482 SI qualified connectors on the 85100AC2016PW50 deliver a rugged, reliable interface for demanding environments. Feature → Business Impact → Application: The 16-contact, 1/3 Bayonet coupling provides fast, repeatable mating with high vibration resistance, reducing maintenance time in aircraft, military vehicles, and industrial automation panels. Practically, this means fewer replugs during field service and lower risk of intermittent connections in harsh conditions. The square flange receptacle with a straight backshell adaptor simplifies panel installation, enabling accurate alignment and secure mounting in compact enclosures, such as control cabinets and equipment bays. This supports faster build cycles and consistent downstream testing, especially when integrating multiple channels and harnesses in complex systems. Feature → Application: With aluminium shell size 20 and a cadmium finish, the assembly remains lightweight yet robust against corrosion, improving service life in outdoor and semi-outdoor installations. The solder cup contact design, loaded delivery, and 16 cavities enable straightforward wiring and reliable terminations, minimizing field rework. The operating temperature range of -40 °C to 125 °C ensures performance across extreme climates while REACH compliance aligns with modern procurement requirements. Overall, the solution reduces downtime, lowers lifecycle costs, and supports scalable panel designs for evolving automation needs.

FAQs
The 85100AC2016PW50 is a square flange receptacle with a straight backshell adaptor, designed for panel mounting in tight spaces. It uses 16 solder cup contacts and a 1/3 Bayonet coupling, enabling secure mating in vibration-heavy environments. Check panel cutouts, for example shell size 20, and ensure the connector orientation (W) aligns with your harness routing and enclosure geometry.
The 1/3 Bayonet coupling provides quick, repeatable mating with strong resistance to loosening under vibration. This reduces the time required for field assemblies and maintenance, minimizes misalignment risk, and supports fast kitting and inventory handling. It is particularly beneficial in aerospace, defense, and rugged industrial installations where reliability is critical.
Yes. The connector operates from -40 °C to 125 °C, covering extreme environmental conditions. It is MIL-DTL-26482 SI qualified and REACH compliant, which helps meet stringent regulatory and industry requirements. This makes it suitable for both aerospace/defense and demanding industrial automation applications where environmental performance matters.
This connector is MIL-DTL-26482 SI qualified, indicating compliance with the MIL standard for sealed circular connectors. It also carries REACH compliance, addressing chemical safety and environmental considerations. These certifications support qualification for aerospace, defense, and industrial markets and facilitate supplier conformity across procurement programs.
The 85100AC2016PW50 features a cadmium-plated aluminium shell, cadmium finish, and a compact 53 mm length with a 36.9 mm square footprint, delivering a lightweight yet durable panel assembly. Delivering with connector and loaded contacts reduces assembly steps, while the solder cup termination and 16 cavities simplify wiring. The combination of quick mating, corrosion resistance, and wide temperature support lowers downtime and total cost of ownership.
