BNC-to-Microdot Adapter Feedthroughs – CF Flange

These instrumentation feedthroughs have BNC coaxial connectors on the air-side and a Microdot connection on the vacuum-side, allowing a means of adapting coaxial connection styles through the vacuum wall. They are typically used for deposition monitors (crystal head sensors), with the Microdot connection in-vacuum to the sensor and the BNC connection to cable to the controller. 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 400°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.
