MHV Feedthroughs - CF Flange, Double-Ended

These instrumentation feedthroughs have MHV coaxial connectors on the air-side and vacuum-side. The alumina insulated conductor is rated for 5000V with a grounded shield and 2500V between floating shield and ground, at 3A. An air-side MHV cable plug is included with the feedthrough but a vacuum-side plug is not. With CF flanges, suitable high temperature vacuum-side plug/cable combination, and the air-side cable disconnected, these feedthroughs are bakeable to 450°C and are UHV-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.
