BNC-to-Microdot Adapter Feedthroughs – Weldable

We manufacture these BNC to Microdot coaxial instrument feedthroughs to transfer low current signals between devices through a vacuum chamber wall.

BNC-Microdot Instrument Feedthroughs Feature:

  • Allow a means of adapting coaxial connection styles
  • Typically used for deposition monitors (crystal head sensors), with the Microdot connection in-vacuum and the BNC connection to cable to the controller
  • Assembly includes a single air-side connector

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.
