4100 Series BIMETAL THERMOSTAT, BRASS PROBE FEATURES • RoHS compliant per EU directive 2002 / 95 / EC • Low-cost brass probe, multiple configurations • Isolated or grounded case • Ideal for immersion sensing DESCRIPTION The Airpax™ 4100 series is a brass probe, bimetal disc immersion thermostat designed to provide low-cost thermal protection in temperature ranges from 40°C to 120°C (104°F to 248°F) in 5°C increments. Its standard gold-plated crossbar contacts allow it to be used in very low-current, low-voltage applications. The 4100 features epoxy/crimp protection that enables it tomeet NEMA 4 and 13 (IP67) standards. It can withstand a variety of harsh environments, including pressure washing. The thermostat is available in both English and metric housings, with a wide assortment of terminations, including standard automotive connectors, in either isolated or grounded case configurations. Typical applications for the Airpax 4100 include monitoring the temperature of engine manifolds, oil, coolant and hydraulic systems. It is also suited to refrigeration systems, heat exchangers and HVAC systems. These applications are found in such varied segments as off-road vehicles, air compressors, marine engines, mining equipment, long-haul trucks, railroads, public transportation and engine- generator sets.

CONTACT OPERATION To build your part number (PN), choose the proper codes from pages 2 to 4. Consult Sensata Technologies when a code Z is used to indicate a special CODE DESCRIPTION requirement. Sensata will assign a unique, customer-specific four digit O Letter “O” = Open on Rise nondescript number. To complete the customer specific part number build, place a “–” dash after the PN proceeded by the assigned four digit nondescript. C Letter “C” = Close on Rise 2.
