Thermal Vacuum (TVAC) chambers simulate space-like conditions for testing space components. To test devices inside the chamber, specifically designed T&M components and cable assemblies are crucial to withstand the pressure and temperature effects. Changes in vacuum conditions can damage cable assemblies if not properly addressed, requiring connectors with slow pressure changes. Maury’s Stability TVAC series employs vented connectors that allow air to escape quickly, enabling rapid pressurization/ depressurization cycles and minimizing delays in testing. Cable assemblies in TVAC chambers experience thermal expansion and contraction, which can affect performance and lead to permanent degradation. Stability TVAC cable assemblies undergo thermal conditioning to relieve mechanical stresses, ensuring reliable performance across varying temperatures.
