Low Outgassing Vacuum Slip Ring
Low Outgassing Vacuum Slip Rings are vacuum slip rings designed with special materials to limit outgassing while in space.
What is a Low Outgassing Vacuum Slip Ring?
The selection of materials is very important when designing slip rings for space applications as slip rings include a wide variety of metals, precious metals, epoxies, plastics, lubrications, etc. Outgassing is a challenge to creating and maintaining clean, high-vacuum environments. The rate of outgassing increases at higher temperatures because the vapor pressure and rate of chemical reaction increases. For most solid materials, the method of manufacture and preparation can reduce the level of outgassing significantly.
Low Outgassing Vacuum Slip Ring applications
Space applications such as SADM – Solar Array Drive Mechanisms utilize slip rings and twist capsules designed for low outgassing.
