SMA Feedthroughs - Weldable, Double-Ended

Photo-FT-IFDCG012011.jpg

These instrumentation feedthroughs have SMA coaxial connectors on the air-side and vacuum-side. Both are matched 50 ohms impedance. The alumina insulated stainless steel conductor is rated at 700V with grounded shield at a maximum current of 1A. (Floating shield double-end SMA feedthroughs are available on request). An air-side SMA cable plug is included with the feedthrough but a vacuum-side plug is not. Feedthroughs of this type are designed for welding into a suitably prepared through-hole in a flange.

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.
