FAQs
The 85100E2016PY50 is built as part of the Eaton Souriau 851 series, featuring a 16-position layout and a square flange receptacle with backnut mounting. It delivers 16 solder cup contacts, aligned for compatibility with standard 851 series mating components and 1/3 bayonet coupling for reliable, panel-mounted assemblies. This simplifies replacement and upgrades within existing 851-based systems.
The receptacle operates from -40 °C to 125 °C, enabling dependable performance in extreme temperatures and high-vibration environments typical of aerospace and industrial equipment. This wide range supports reliable solder contact integrity, mating stability, and long service life, reducing unexpected downtime in harsh field conditions.
Yes. The 85100E2016PY50 is MIL-DTL-26482 SI qualified, ensuring adherence to a rigorous military standard for interconnects. This qualification provides confidence in mateability, environmental performance, and overall electrical reliability for mission-critical applications.
Backnut mounting provides a secure, sealed interface with straightforward panel mounting, while the 1/3 bayonet coupling reduces installation torque and enhances vibration resistance. Together, they deliver faster field assembly, easier maintenance, and repeatable mating in constrained spaces common to aircraft and heavy equipment.
Solder cup contacts are cadmium-plated for corrosion resistance and rely on a robust aluminum shell. Regular inspection for secure contact seating and minimal solder joint degradation is advised, especially in high-temperature or high-vibration environments. When replacement is needed, the 851 series compatibility supports straightforward field upgrades with minimal downtime.
