Vacuum coater electron gun high voltage ceramic sealing

The power feedthrough with CF type vacuum flanged fitting. It is a electrical feedthrough and conveys high-voltage, high-amperage power into high-vacuum environments for operating heating coils in sputtering, coating and other demanding material evaporation applications or experiments.

Pasamuros (or vacuum feedthroughs) come in many forms to transfer electrical currents, signals, fluids, gases or mechanical movements from outside the vacuum (air side) to the inside (vacuum side) of a vacuum chamber to equipment within the chamber. The entry point for the feedthrough must be vacuum-sealed via a suitable through hole. The feedthrough can be weldable (weld-on) or connected with a CF, KF or ISO vacuum flange to the vacuum chamber.
