CODE RED™ Lightweight Hermetic Sealing Connectors"Mission-Critical" Hermetic Sealing with 1x10-7 Leak-Rate Performance, Lower Electrical Resistance and Lighter Weight Hermetically-sealed interconnects used in vacuum or high-altitude applications prevent moisture and other contaminants from damaging sensitive electronic equipment. Glass-to-metal hermetic sealing has been the gold standard in the aerospace and petrochemical industries for decades due to the strength and long-term durability of the materials used. But glass-to-metal seal hermetics come with a big price tag in both weight and electrical resistance. |
