BNC Feedthroughs - CF Flange, Double-Ended

These instrumentation feedthroughs have BNC coaxial connectors on the air-side and vacuum-side. Connector-plug combinations are offered with unmatched 48-52 ohms impedance or matched 50 ohms impedance. Air-side plugs are included with the feedthrough but vacuum-side plugs are 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.
