Power Feedthroughs - KF Flanged, 1,000-1,500 Volts

These electrical power feedthroughs are rated to 1500V. The various conductors are insulated with alumina and rated up to 25A. The KF flanges are sealed with a centering and O-ring combination (not supplied), making them high vacuum compatible.

Note:

The electrical and thermal ratings specified are of safe operating limits determined by various factors including material properties, mechanical design, and the intended operating environment. All electrical ratings are based on operation with one side in dry atmosphere and the other side in vacuum of less than 1 x 10^-4 Torr. All VacuCAD files as well as any dimensions shown or listed in our ordering tables do not include manufacturing tolerances and are provided for reference only.
