Hermetic Seals for Space Simulation System

Space simulation facilities have the most challenging technical requirements and delivery time constraints of any type of vacuum system, and need a wire feedthrough, and cable harness manufacturer they can rely on. That’s why every major space simulation facility in the world depends on our hermetic bulkhead connectors, hardwired hermetic wire feedthroughs, hermetic cable harnesses, and hermetic fiber optic feedthroughs. Our hermetic electrical feedthroughs allow for the connection of power and signal within the TVAC (Temperature and Vacuum Chamber) environment. A broad range of design options include high-density wire harness packages and in-line quick disconnects, like our PBTR PotCon, that allow easy testing via existing instrument connectors. Expedited shipping options are also available.

New Case Study

Douglas Electrical Components is focused on providing the custom electro-mechanical assembly to meet your needs. Select virtually any connector, wire, cable, or fiber, and Douglas will work to integrate it into a hermetic bulkhead assembly. From sourcing to assembly, our LEAN manufacturing operation will build made-to-order assemblies with a fast turnaround time. With in-house CNC machining, we maintain control over our operation to deliver on-time and at a competitive price point.
