9 Pin Vacuum Feedthroughs

9 Pin Vacuum Feedthrough

Need Circular Flange, Pin Contact Feedthroughs? Give BCE a Call!

Nine pin circular feedthroughs (often called instrumentation feedthroughs) are commonly used for the transmission of low power electrical signals. They are designed for applications where typical Subminiature Type-D connections will not fit, or where there is little space. The circular geometry allows the installation of this feedthrough into very small vacuum flanges. They are often used in instrumentation applications such as semiconductor processing, electron microscopy, and a variety of analyzers.
