Douglas Electrical Components provides hermetic feedthrough solutions for the demanding requirements of space simulation facilities, where vacuum performance, reliability, and fast delivery are critical. Major facilities across North America rely on Douglas products such as OptiSeal™, PotCon®, DuctorSeal®, StudSeal™, and CircuitSeal™ to maintain vacuum integrity while transmitting power, signal, and data through chamber walls.

These solutions offer a wide range of design flexibility, including high-density wire harness packages, in-line quick disconnects, and drop-in replacements for existing connectors such as Deutsch DM5623. DuctorSeal feedthroughs seal directly to stranded wire, shielded cable, multi-conductor cable, and thermocouple wires, reducing voltage drops and minimizing wiring errors while improving reliability.

Douglas supports high-frequency applications exceeding 18 GHz and high-voltage designs above 30 kV, along with cryogenic solutions operating down to -270°C (3 K). Their NASA-certified low-outgassing epoxy meets ASTM E-595 standards, making it ideal for sensitive vacuum and aerospace environments. Vacuum bake-out services are also available for added performance assurance.

Connector options include industrial and MIL-spec designs from major manufacturers such as Amphenol, ITT, Tyco, Molex, and Lemo, including MIL-C-38999, Micro-D, Nano-D, D-Sub, and other standard aerospace connectors. Applications range from fiber optic ConFlat flanges and high-frequency RF systems to large PortPlate assemblies supporting thousands of feedthroughs, ensuring reliable performance in advanced space simulation and aerospace testing environments.
