Vacuum Wire Feedthrough & Electrical vacuum feedthrough

Our vacuum electrical feedthroughs are precision-engineered to create hermetic seals for electrical connections, ensuring leak-free performance that meets stringent specifications. While we do offer standard off-the-shelf products, our customized feedthroughs are tailored to your exact requirements, combining multiple power, signal, and optical connectors along with diverse wire and cable types in a single housing.

Our advanced epoxy technology enables higher design flexibility and robust performance, even in singular designs like our D-sub Connectors and Micro-D hermetic connector feedthroughs. With a typical leakage rate of less than 1×10-9 cc-He/sec, you can trust Douglas Electrical Components for reliable vacuum electrical feedthroughs, vacuum power feedthrough, vacuum feedthrough connectors and vacuum pass-through connections.

Hermetically seal virtually any conductor or fiber (thermocouples, shielded wires, etc.) in standard vacuum fittings.

Features

TECHNICAL ADVANTAGES
  • Ultra-High vacuum feedthroughs with designs that can accommodate up to 500 conductors at lengths up to several hundred feet.
  • Low outgassing epoxy (0.25% TMA, 0.00% CVCM) available in wire feedthrough, PotCon, StudSeal™ and fiber optic configurations.
  • Direct sealing of shielded conductors to any vacuum hermetic feedthrough flange design.
  • Our electrical feedthroughs are leak-tight, and one hundred percent leak tested with typical leakage rates less than 1×10-9 cc-He/sec.
  • Hermetic sealing capability to a variety of industry standard electrical connections in low, medium, and high volumes.
  • High voltage vacuum applications to 35 kV.
  • Decades of experience building sealed connectors, and fully connectorized hermetic and non-hermetic cable assemblies.
  • Cryogenic designs for temperatures down to -270°C (3 K).
POPULAR VACUUM FLANGES
  • CF flanges: Characterized by their flat sealing surfaces using a copper gasket interface. They are often used in high-vacuum systems because they provide a high-quality, leak-tight seal.
  • KF flanges: Similar to CF flanges, but have a flanged collar instead of a clamping mechanism. They are often used in medium-vacuum systems.
  • ISO flanges: These are standardized flanges that are commonly used in low-vacuum systems. They have a projecting collar and are sealed with an O-ring.
  • NW flanges: Standardized flanges that are similar to ISO flanges, but have a smaller size range. They are often used in small-scale vacuum systems.
  • RF flanges: Sealed with a metal-to-metal seal, and are often used in high-vacuum systems where a leak-tight seal is required.
