Sub-C Feedthroughs Drawing

Subminiature-C (Sub-C) Feedthrough, Conflat CF Flanges.

Subminiature-C (Sub-C) multipin hermetic feedthroughs are designed for applications where space is limited inside your vacuum chamber.

This compact and unique 9-pin design allows installation into a 1.33-inch CF flange or two feedthroughs on a 2.75-inch conflat CF flange.  Nine gold-plated pins are arranged in a straight through pin-to-pin design and are hermetically sealed and electrically insulated in a stainless steel shell using the latest in glass-ceramic bonding technology.

Sub C Feedthrough flange "kit" additional features:

  • All of the above features (Feedthrough Flange)
  • In Vacuum cable assembly:
    • PEEK Sub-C connector to Kapton insulated cable assembly, 19-inches long.
  • Air Side cable assembly:
    • Delrine Sub C connector to cable assembly, 96-inches long.

All feedthroughs are mounted on CF Flanges that incorporate the industry standard "captured copper gasket" sealing principle, making it easy to mount to your existing CF Flange ports.
