6700 Series TO-220, Subminiature Bimetal Disc Thermostat FEATURES • RoHS compliant per EU directive 2002 / 95 / EC • Gold-plated contacts • TO-220 / Y-220 international electronic package standard • Up to 20,000 life cycles @ max standard amperage • Ideal for surface and air sensing on PC boards and heat sinks • Up to 100,000 life cycles @ max gold contact amperage • VDE approved with “P” bracket option DESCRIPTION The Airpax™ 6700 series is a RoHS compliant, positive snap action, single pole / single throw, sub-miniature bimetallic thermostat which provides accurate and reliable sensing and switching in a single device. The 6700 series thermostat dimensionally conforms to the international product package standard Y220 / TO220. Thus, the 6700 may be automatically placed and soldered onto PC boards with high speed automated equipment, eliminating the need for the expensive hand placement and termination required today for most power supply thermostats. The 6700 provides fast, positive response with excellent repeatability. The thermostat has a switch capability of up to 0.5 amp for 48 VDC, and achieves low-level switching down to 0.001A to 0.020A at 5 VDC for 100,000 cycles. Temperature is pre-set at the factory and is non-adjustable in the field. Thermal conductivity is mainly through the terminals and the mounting bracket making the unit ideal for both surface mount and ambient air sensing. The nickel-plated copper mounting bracket comes standard, or you can utilize the laminated plastic mounting bracket for increased dielectric strength and VDE approval. Primarily developed for thermal management applications on power supplies, the Airpax™ 6700 series is also ideally suited for use on crowded PC boards. Typical uses include turning on an indicator light, sounding an audible alarm, switch on a control circuit to send a message to a display screen or even switching a circuit to shut down a system. Applications include computers and computer peripherals, aircraft, automotive, medical devices and test equipment.
