SMA Feedthroughs - Weldable, Double-Ended

These instrumentation feedthroughs have SMA coaxial connectors (50 Ohm matched impedance) on the air-side and vacuum-side. 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.
