Ethernet CAT5 CAT6 RJ45 Vacuum Feedthrough CF35
An Ethernet Vacuum Feedthrough is a component that will enable you to run ethernet cables into the vacuum chamber from the outside to the inside of the chamber during vacuum operations without compromising the vacuum. This CF35 Vacuum Feedthrough is compatible with RJ45, CAT5, CAT6, and ethernet LAN connections.
The CF35 vacuum feedthrough (often compatible with or equivalent to DN35/DN40 ConFlat, 2.75" outer diameter) is a specialized hardware component used to pass electrical power, signals, optical fibers, or data lines into an ultra-high vacuum (UHV) or high-vacuum chamber while maintaining a hermetic seal.
