  • Hermetic Feedthroughs Safeguard Mission-Critical Electronics
    From automotive electronic control units to weather satellites and defense systems, electronics failures can bring communications and critical functions to a sudden halt. Experts specializing in electronics failure analysis can list a host of reasons for various malfunctions, but one of the most
  • The six challenges of specifying and procuring hermetic feedthroughs for space simulation
    The purpose of this white paper is to share the details and knowledge that engineers at Douglas Electrical have gained over the years regarding the specification and sourcing of hermetic seals and feedthroughs used in space simulation vacuum chamber applications. Having worked with most major space
  • New Cryogenic Feedthrough Improves Ease-Of-Use
    Epoxy-based hermetic feedthroughs have worked well in cryogenic systems for years. But the design modifications needed to operate in these extremely cold temperatures increased the size of the feedthrough and limited your mounting options. We recently eliminated these issues with an entirely new
  • Why Consider Ceramic Feedthroughs
    Ceramic feedthroughs are ceramic-to-metal fabrications that are utilized to transmit electrical signals, high currents/gases/fluids, or high voltages from between external sources to a hermetically-sealed chamber.
  • When Wire Feedthroughs Make Sense
    cost, impose unnecessary mechanical design constraints and trigger electrical problems. So what's the alternative? Wire feedthroughs hermetically sealed with epoxy.
  • Meeting Feedthrough Challenges on the A-3 Test Stand
    The purpose of this paper is to share the experience and knowledge that engineers at NASA and Douglas Electrical have gained regarding the specification of hermetic seals and feedthroughs used in engine test stand vacuum chamber applications. This paper looks specifically at the experience
  • Moisture-resistant sealing materials for downhole HPHT electrical feedthrough packages
    Downhole logging tools and electrical circuits are packaged in a hermetically-sealed metal enclosure, which is either sealed and pressurized, or filled with fluid, to protect the circuits from downhole corrosive environment and humidity. The sealed tool enclosure uses an electrical feedthrough
  • Lean Initiative Enables U.S. Manufacturer to Stay Competitive, and Stay Onshore
    The purpose of this white paper is to share the details and knowledge that engineers at Douglas Electrical have gained over the years regarding the specification and sourcing of hermetic seals and feedthroughs used in space simulation vacuum chamber applications. Having worked with most major space
