Electrical Vacuum Feedthroughs (or, Vacuum Feedthroughs) transmit electrical signals from outside the vacuum chamber to equipment on the inside. Our hermetic sealed vacuum feedthroughs are designed for rough vacuum to high vacuum and ultimately to ultra-high vacuum. The range of vacuum needed depends on the type of flange required. NPT Feedthroughs are usually used for rough vacuum while ISO and NW (also known as KF or QF) are more high vacuum oriented. UHV or ultra-high vacuum use the metal sealed ConFlat (or CF) vacuum flanges.
Types of feedthroughs
-Multi-Pin, Sub-Min C or Sub-Min D - Used for low power or instrumentation power applications
- Power Feedthroughs - Used for transmitting power into the vacuum chamber system
- Thermal Conductor Feedthroughs - Used to control temperature to a device inside the vacuum chamber
- RF Power - Used for RF Power transmission
-Coaxial Feedthroughs - BNC, MHV, SHV, MicroDot signals for instrumentation applications
Most Electrical Vacuum Feedthroughs are currently 4-5 Weeks Lead time

Multi-Pins
"Multi-pin" describes feedthroughs with more than one conductor path and connectors on either one or both sides. Multi-pin feedthroughs are perfect for instrumentation applications.

High Voltage Power
High Voltage Power Feedthroughs are used for the transmission of high voltage power and/or current into vacuum or glovebox systems.

Coaxial
Coaxial feedthroughs are electrical feedthroughs with parallel and concentric conductor paths. The inner most conductor path is electrically isolated from the vacuum flange. Models include Grounded Shields and Floating Shields. The Grounded Shield feedthroughs have one isolated path, and the Floating Shield models have two isolate paths.

Thermocouple
Thermocouple Feedthroughs communicate with temperature measurement systems, but do not measure temperature themselves. These feedthroughs conduct the thermocouple's voltage signal from inside the vacuum to an external device.

Breaks & Envelopes
Breaks are tubular isolators with metal adapters brazed on each end of a ceramic isolator. Breaks and envelopes are used for voltage insulation. Cryogenic breaks are normally standard in cryogenic fluid. Coolant fluid lines sometimes require an electric break.
