Hermetic electrical connectors provide a gas- and liquid-tight seal, making them safe for sealed environments across sectors like aerospace, automotive, and oil & gas. These connectors, including custom hermetic feedthroughs, enable power and signal transfer into sealed electronic enclosures and control systems.

Ideal for both vacuum and positive pressure applications, hermetic connectors maintain chamber vacuum and prevent leaks, ensuring secure, gas-tight connections. Without a hermetic seal, critical applications risk moisture intrusion, explosions, or other failures. Our hermetic feedthrough connectors are reliable, cost-effective, and easy to assemble. With over 40 years in industries like military, aerospace, space simulation, high-radiation gloveboxes, and x-ray systems, connectors meet key explosion-proof ratings such as UL, FM, IECEx, CSA, and ATEX.

Using epoxy for flexibility, we can integrate pins, sockets, terminals, wires, cables, in-line connectors, flex circuits, and optical fibers into assemblies. This encapsulation ensures a true hermetic seal, provides strain relief, and simplifies OEM integration.

A Circular Hermetic Connector is a specialized, gas-tight connector designed to seal against moisture, gases, and contaminants, crucial for industries like aerospace and military. These connectors are customizable in size and materials, providing liquid-tight sealing and reliable connections in challenging environments.

Unlike circular connectors, hermetic rectangular connectors have a linear design and can accommodate various pin counts and sizes for diverse applications. These connectors are typically installed with threaded screws, while circular connectors use threading to interconnect. Hermetic sealing for rectangular connectors can be achieved via backpotting or designing a hermetic rectangular feedthrough.

A hermetic feedthrough is a sealed connector that blocks gas and liquid from passing through an enclosure, commonly achieving a leak rate of <1×10⁻⁸ cc-Helium/second. For electrical applications, a hermetic feedthrough prevents leakage from one side (vacuum) to the other (atmospheric pressure). Custom hermetic feedthroughs use epoxy to seal within the bulkhead, providing a robust seal between pressure and atmosphere.

A hermetic wire feedthrough is an electrical connector that transmits signals or power through a hermetically sealed barrier. The hermetic seal blocks gases and liquids, protecting components from moisture, dust, and other contaminants. Compared to traditional connectors, hermetic wire feedthroughs have lower electrical losses, ensuring better signal integrity.

A vacuum feedthrough is a hermetic feedthrough specifically designed to maintain a vacuum environment, commonly used in systems like vacuum chambers, gloveboxes, and semiconductor equipment. These feedthroughs connect vacuum pressure on one side to atmospheric pressure on the other, typically using flanges (CF, KF) or O-ring seals for integration into standard industry ports.

Epoxy-based seals offer greater design flexibility, allowing conductors to pass directly through, simplifying assembly. Epoxy allows closer conductor spacing, achieving higher density within a smaller space than glass-to-metal seals. Epoxy-based seals can also be more cost-effective and have shorter lead times.

Yes, connector plugs (male) and receptacles (female) can be integrated into assemblies, providing fully tested and simplified solutions. If hermetic connectors require additional sealing, an epoxy potting treatment (PotCon series) can fill gaps in third-party connectors to meet leak specifications.

Mechanical and electrical testing is available, including leak tests, bubble tests, and vacuum leak testing for certification. High-potential (Hipot) testing verifies each feedthrough’s electrical performance.

Custom and semi-custom hermetic electrical feedthroughs are manufactured based on customer specifications, combining commercial-off-the-shelf (COTS) parts with in-house machining to create cost-effective solutions.

Cable feedthroughs contain jacketed cables within the housing, while wire feedthroughs seal individual conductors. Epoxy-based cable feedthroughs can hermetically bond to cable jackets to prevent leaks.

The number of conductors in a hermetic wire feedthrough depends on wire gauge, conductor count, and the feedthrough’s internal diameter, allowing higher density compared to glass-to-metal seals.

Wire bushings, also known as line bushings, hermetically seal wires or cables within a fitting like a threaded conduit. Common in the oil and gas industry, wire bushings prevent fluid or gas ingress.

Wire feedthroughs reduce costs by replacing multiple connectors, simplifying assembly and supply chains, and avoiding unnecessary specifications, making them a cost-effective alternative to bulkhead connectors.

A hermetic power feedthrough allows power or signal transfer through a sealed barrier, like a vacuum or pressure vessel, while preserving a hermetic seal. This design ensures safe and reliable transfer of electrical power or signals across environments with different pressures or conditions.

Standard materials for hermetic power feedthroughs include copper or brass for conductors/terminals and aluminium or stainless steel for housings. Customization is possible based on specific application needs for temperature, pressure, or chemical resistance.

Hermetic power feedthroughs are widely applied in industries such as aerospace, defense, industrial manufacturing, glovebox technology, cryogenics, hazardous locations, medical equipment, and semiconductor manufacturing. They’re also essential for R&D applications, including vacuum chamber experiments.

Hermetic power feedthroughs are generally installed by drilling a hole in the barrier and securing the feedthrough in place with a nut or fastener. Installation methods may vary according to the specific application and type of barrier.

Hermetic power feedthroughs can include integrated connectors or wires for power transmission. Hybrid designs that support power, signal, and even optical fiber within the same feedthrough are also available to meet varied application requirements.

Hermetic power feedthroughs can withstand extreme temperatures, from cryogenic levels up to 200°C, and handle pressures up to 10,000 PSI, ensuring durability and performance in diverse environmental conditions
