Thermal engineers count on the reliability of Sensata | KLIXON® 11041 thermostats for the demanding environments required on satellites, launch vehicles, and manned space vehicles. For over sixty years, the exceptional vibration and shock resistance enabled thermal control on programs such as GPS, DAWN, James Webb Space Telescope, Space Shuttle, Delta II, Atlas V, and many others. Each 11041 thermostat is vacuum baked and backfilled with inert dry nitrogen atmosphere prior to final sealing to prevent condensation at low temperatures or possible contact contamination at high temperatures. All Sensata space flight thermostats are assembled in a Class 100/ISO 5 cleanroom and undergo Group A Inspection per Table I of NASA S-311-P641. Inspections include pre-cap visual inspection, millipore cleaning, run-in, vibration, particle impact noise detection (PIND) in addition to the standard tests for calibration, creepage, seal, dielectric withstand voltage, insulation resistance, and contact resistance. Each individual thermostat is serialized and shipped with all inspection/screening test data included in the end item data package.
