Douglas Electrical Components
Driving Hermetic Feedthrough Technology
Douglas Electrical Components developed the industry’s first epoxy-based wire harness feedthroughs in 1975. Since then, we have continuously improved our epoxy-based sealing technologies. And today, our hermetically sealed feedthroughs and connectors thrive in the most demanding application environments – from oil fields to battlefields to outer space.
Epoxy-based sealing technologies that perform
With its robust mechanical properties and resistance to temperature extremes, epoxy is an ideal material for creating lasting hermetic seals around wires and connectors that pass into pressure or vacuum systems.
- Hermetically sealed connectors
- Hermetically sealed feedthroughs
- Hermetic fiber optic bulkhead connectors
- Sealed coaxial connectors
- Sealed flex connectors
- Electrical feedthroughs
Our epoxy and epoxy-hybrid feedthroughs and connectors withstand the most stringent performance requirements:
- Vacuum to 1x109 Torr.
- Pressures as high as 15,000 psi.
- Temperatures from -100 to +350°F.
- Wire gauges from 38 AWG to 500 MCM.
- Conductor counts from single wire to 3,200 in a single feedthrough.
- Cable lengths from stubs to 2,000 meters.
We have capabilities for a range of lot sizes and quantities – including one-of-a-kind assemblies that weigh 2,000 pounds to recurring production lot sizes in excess of 250,000 pieces per year.
Our hermetically sealed feedthroughs and connectors serve in a variety of demanding applications, including advanced weaponry for the military, downhole oil and gas equipment, magnetic medical imaging systems, high-performance electric switchgear and semiconductor manufacturing machines.
Solving your wire and connector sealing challenges
Our customers have encouraged the evolution of our hermetically sealed feedthroughs and connectors, often in response to sealed ceramic connector that have failed or driven too much cost. With innovation after innovation resulting from our responses to customer design challenges, our engineers are always happy to help you solve your most difficult sealing applications.
