Douglas Electrical Components - Model DuctorSeal Series -Hermetic Wire & Cable Feedthroughs

Ultimate Design Flexibility

Each end of the bulkhead can be customized to feature wires, jacketed cables, or connectors, with the hermetic sealing point located within the epoxy of the bulkhead at the conductor. DuctorSeal’s epoxy-sealed feedthroughs are designed to meet leak-rate requirements, even in stranded wire applications, and comprise precision-machined housings made from materials such as aluminum, titanium, stainless steel, brass, specialty alloys, and plastic. A variety of mechanical interfaces are available including threaded connections, flanges, and customized fittings.

To simplify installation, Douglas Electrical Components offers integrated terminals and connectors at each end of the wires and cables, saving time on the factory floor or in the field. If you’re potting cables in your operation, Douglas offers the expertise to do this process efficiently, with fully tested assemblies ready for use. Virtually any connector type can be integrated, with Douglas sourcing all components according to your needs.

Our custom hermetic feedthroughs can withstand a range of environments, with vacuum capabilities from 1×10^-10 Torr to pressures of 15,000 psi. Operating temperatures range from 4 K (LHe) to 200°C. High voltage and low cross-section sealed wire feedthroughs operating up to 30kV-DC are also available.
