Vacuum systems require highly reliable, leak-tight electrical connections, and Douglas Electrical Components provides industry-leading vacuum electrical feedthroughs designed for Ultra-High Vacuum (UHV) and high-vacuum applications.

Engineered for pressures as low as 10?¹? Torr, these feedthroughs deliver hermetic performance with extremely low leak rates and are fully helium leak tested for quality assurance. Both standard and custom designs are available, allowing integration of power, signal, thermocouples, fiber optics, and complex cable assemblies within a single vacuum-compatible solution.

Advanced low-outgassing epoxy technology enables flexible, high-density configurations while maintaining long-term vacuum integrity. Designs can support hundreds of conductors, high-voltage applications up to 35 kV, and cryogenic environments down to 3 K.

Compatible with CF, KF (QF), ISO, NW, and RF flange systems, these feedthroughs are used across semiconductor manufacturing, cryogenics, space simulation, research labs, and industrial vacuum systems.

With over 80 years of expertise, Douglas Electrical Components delivers fast-turn, made-to-order vacuum feedthrough solutions that reduce design complexity, save space, and ensure reliable performance in the most demanding environments.
