  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 approach to cryogenic feedthrough design.   Intended for use in space simulation, laboratory […]

We’ve shipped our share of standalone hermetic feedthroughs over the years. Increasingly, however, sealed hermetic penetrations leave our plant as a part of a value–added assembly. These turnkey assemblies typically combine our hermetic feedthrough technologies with non-hermetic connectors, printed circuit boards, flex circuits and wire harnesses. Assemblies can also incorporate strain relief, water-blocking overmolds, jacketing, shrink tubing, breakouts, mechanical subassemblies and patch […]

With medium-voltage switchgear, progress is being made with regard to finding alternatives to SF as an insulation gas. Designs that incorporate dry air or a mixture of fluoroketone, nitrogen and oxygen as the insulating gas are being explored to minimize environmental impact. Oil, vacuum and CO are other alternatives to SF. Regardless of the type […]

It’s tough enough to design safe electrical systems for hazardous locations without having to worry about the UL listings for each and every component you use. We’ve just made things a bit easier for you with a new line of UL listed explosion-proof wire bushings.   Our epoxy-based NPT bushings feature a UL 1203 listing, which addresses […]

Douglas Electricals’ new cryogenic hermetic feedthroughs with epoxy improve ease-of-use for true hermetic feedthrough performance. This direct-seal, hermetically sealed wire feedthrough technology works with our PotCon®, DuctorSeal® and  OptiSeal™ products.  Watch the video about our cryogenic hermetic seals to learn more about our hermetically sealed connector, aerospace connector, hermetic seal, and feedthrough connector technology.   Our latest feedthrough is an example […]

To reduce the risk that electrical outages will cause production delays that affect our customers, we recently invested more than $500,000 in a new combined heat and power (CHP) generator for our 30,000 square foot manufacturing facility. This system works in conjunction with our existing roof-mounted solar panels, which were installed in 2012.   The […]
