Thermal engineers count on the reliability of Sensata | KLIXON® M2 thermostats for the demanding environments required on satellites, launch vehicles, and manned space vehicles. For over sixty years, the tight set point temperatures, as well as exceptional vibration and shock resistance, enabled precise thermal control on satellites such as GPS III, JCSAT-9/-10, the Hubble Space Telescope, SPACE-X Dragon and many others. Each M2 Series Narrow Differential 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.
