The 5003 series is a RoHS compliant, positive snap action, single pole / single throw, bimetallic thermostat which provides accurate and reliable sensing and switching in a single device. It is ideal for applications when space is at a premium with overall depth, without projecting terminals, being only 0.250 in. The basic switch assembly is operated by a bimetal disc with positive, reinforced snap-action, which is known for its reliable repeatability.

With several terminal and mounting options, the 5003 series offers excellent shock and vibration resistance due to the robust construction of its switch assembly. For high humidity and contaminating atmosphere applications, the device is sealed with a non-volatile resin. Narrow differential devices are ideal for control, while standard differentials can be used for high or low temperature limit switches.
