Utilized in high-vacuum environments up to 10^-10 Torr, our vacuum feedthroughs have been trusted by top research and vacuum facilities and OEM production equipment worldwide for decades. Partner with our team to design a vacuum electrical feedthrough that is made-to-order within weeks of design, saving you time, design effort, space, and money.

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.

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.
