FAQs
The 85100E1811SW50 uses a backnut backshell with a straight orientation and 1/3 bayonet coupling, enabling fast mating with secure retention. Its W orientation and socket (female) contacts simplify integration into existing harnesses, while maintaining vibration resistance in harsh environments. This makes field assembly more predictable and reduces downtime during panel upgrades or maintenance.
Yes. This receptacle is part of the Eaton Souriau 851 series and features 11 solder cup contacts in a socket (female) configuration. The 1/3 bayonet coupling provides reliable locking, while the aluminium shell with cadmium plating offers corrosion resistance. Compatibility with mating plugs is ensured by the standard 851 series interface and square flange receptacle design.
The 85100E1811SW50 is designed for operation from -40 °C to 125 °C, supporting applications in extreme environments. This wide temperature range makes it suitable for aerospace, industrial automation, and defense deployments where environmental conditions fluctuate and reliability is critical.
This connector is MIL-DTL-26482 SI qualified, delivering a high level of military-standard assurance. It is also REACH compliant, addressing regulatory concerns for restricted substances. Designers should consider cadmium plating implications for RoHS or supplier-specific requirements when integrating into certain programs.
The 85100E1811SW50 delivers reliable mating under vibration, reduced field maintenance due to robust solder-cup terminations, and easy installation with the backnut backshell. Its compact 11-contact layout supports scalable signaling while maintaining a lightweight aluminium shell, contributing to lower total cost of ownership, shorter install times, and higher overall equipment availability.
