Hermetically sealed interconnects used in vacuum or high-altitude applications prevent moisture and other contaminants from polluting sensitive electronic equipment and other payload technologies. Glass-to-metal hermetic sealing has been the gold standard in the aerospace industry for decades due to its reliable long-term performance, but application engineers employing conventional hermetic interconnects pay a heavy price to prevent sensitive vacuum-sealed equipment from gas and moisture ingress/damage as these interconnects famously suffer from heavy weight and high electrical resistance.
Code Red is a proprietary sealing adhesive and application process invented by Glenair that for the first time ever provides durable hermetic sealing in a lightweight aluminium package. In addition, it allows for the use of conventional gold-plated copper alloy contacts, significantly improving the electrical performance of the system. Code Red is available in Glenair SuperNine (D38999 Series III type) and Series 80 Mighty Mouse connectors, and delivers reliable, life-of-system 1x10-7 maximum leak rate hermetic sealing.
Connectors utilising Code Red hermetic adhesive sealing went through a gruelling qualification test and validation process to validate material sealing durability and hermeticity. Validation testing included 100 cycles of thermal shock at -65°C to +200°C while maintaining hermeticity, followed by 1000 hours of thermal ageing at 200°C.
