Abstract
The results of endurance tests on two Torr TF2 relays are reported. Each relay was operated in vacuum at approximately 25C with 28V coil voltage and 8A contact current for 10 days. Measurements were made at -15, 25 and 65C. Deterioration in thermal conductivity between the coil windings and relay case was observed in some instances when the temperature was reduced between tests, resulting in increases of 50 to 80C over the original operating temperatures.
