BNC-to-Microdot Adapter Feedthroughs – Weldable

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. These feedthroughs are designed to be welded into a suitable through-hole in a flange.
