Understanding Electrical Feedthroughs

Glass-to-metal seals are more effective than O-rings and epoxy when it comes to maintaining an hermetic seal. Sometimes, glass isn’t effective at high voltage or high operating temperatures. The solution is a ceramic-to metal seal and electrical feedthrough. Although there is more labor and time involved in creating this type of seal, it will work…

Getting the Right High Vacuum Feedthrough

A hermetic feedthrough must be secure enough to prevent leakage, even the smallest amount. It has to maintain a vacuum under certain conditions, which are different for every application. Fortunately, there are three main types of feedthroughs which operate in hermetic vacuums:   Low voltage Water-cooled and RF High-voltage   We have the experience to…
