Amphenol D38999 G Class Series III Connectors with Vacuum Degassing
What is Vacuum Degassing?
Degassing (or gas-off) is required of connectors and other components in space applications. As the name implies, the connectors must go through a vacuum outgassing procedure to remove harmful materials, per rigorous NASA or military specifications.
While these construction materials are normal on earth based applications, they can become extremely hazardous in a space vacuum environment. Chemical or organic substances trapped inside materials (plastic, glue, coatings, etc.) could evaporate in the vacuum of space and re-condense on a cooler surface. These surfaces might include optical or electronics components whose performance could be impaired or damaged by this surface condensation.
Assembled connectors are "baked" at high temperature in a high-vacuum environment to evaporate and extract potentially harmful substances trapped inside the normal construction materials. Powell vacuum oven system can achieve a maximum operating temperature of 300°C (572°F) at 10-6torr vacuum range to meet the needs of any space qualification specification.
No. This is a very specialized value-added capability that Powell is pleased to offer its customers.
