FAQ
Why are feedthroughs important?
Vacuum feedthroughs play an essential role in vacuum technology, ensuring a secure and leak-tight connection between the internal and external parts of a vacuum system. They allow elements such as electrical cables, cooling water pipes, and mechanical components to pass through without compromising the vacuum. These components are critical for applications requiring precise pressure and environmental control, enabling efficient system operation and minimizing production errors.
What types of feedthroughs are available?
Power vacuum feedthroughs
Robust ceramic-to-metal feedthroughs have electrical ratings for operation, with one side in dry atmosphere while the opposite end is fitted in stable vacuum. Applications include ultra-high vacuum systems with CF flanges or high vacuum systems with NW flanges. Materials include high alumina ceramic insulators, OFHC® copper and nickel conductors, and 304 stainless steel flanges.
High voltage ceramic break insulators
Vacuum insulators (breaks and isolators) electronically isolate one component in your vacuum system from another. Maximum voltage for insulators is 3-15KV, depending on size. Our ceramic insulators are UHV compatible.
Thermocouple vacuum feedthroughs
Thermocouple feedthroughs carry instrumentation signals while providing electrical isolation and hermetic sealing. Insulators are made of high-purity, high-strength, low-loss alumina ceramic, and feature -20°C to 150°C elastomer seals.
Instrumentation vacuum feedthroughs
Our 8 pin, 2 amp instrumentation feedthroughs transmit signal voltages and currents. Process control in surface analysis, electron microscopy and electron beam evaporation are typical applications. Multi-Pin, BNC coaxial, and MHV coaxial feedthroughs are available.
Liquid / Gas vacuum feedthroughs
Single and dual tube feedthroughs reduce condensation and ice buildup on the atmosphere side of the feedthrough and the mounting flange interface. Liquid / Gas feedthroughs are available without fittings or terminated with industry standard Swagelok® or Cajon® VCR tube fittings.
LN2 vacuum feedthroughs
Liquid nitrogen feedthroughs are constructed with dual and coaxial tube geometries to reduce condensation and ice buildup on the atmosphere side of the feedthrough around the mounting flange interface, protecting the seal’s integrity. Tubing is .25- and .375-inch OD with CF or NW flanges.
For which applications are electric and water-cooled feedthroughs used?
We manufacture both custom and standard vacuum feedthroughs designed for medium, high, and ultra-high vacuum applications. The performance of each feedthrough depends on its design and materials, ensuring optimal functionality for specific requirements. Frequent applications of our vacuum feedthroughs include:
- Semiconductor industry
- Research laboratories
- Energy and aerospace
- Life and health sciences
