Hermetic Feedthrough
Glass To Metal Seal Hermetic Feedthrough An electrical conductor that carries signals and electric power through an enclosure or environmental barrier is named a feedthrough . For some applications like aerospace and defence, the feedthrough must be protected against extreme conditions and be engineered for very high reliability. They require robust seals that maintain electrical integrity and long life environmental sealing. This is often the kind of application where glass-to-metal-seal technology is best applied. Feedthroughs require hermetic or airtight seals that can withstand severe conditions such as high temperature, high pressure, vibration, moisture, and difficult chemical environments. Glass-to-metal-seal (GTMS) feedthroughs have high reliability and high-performance capabilities. Glass-to-metal sealing is a technique to hermetically insulate electrical conductors that pass from one side of a barrier to the other side using special co...
