Airpax Series 6700 Thermostat
The Airpax Series 6700 is a miniature bimetallic snap acting thermostat which provides accurate and reliable sensing and switching in a single device. Primarily developed for thermal management applications on power supplies, the Series 6700 is also ideally suited for use on crowded P.C. boards. It provides fast, positive response and excellent repeatability with 1amp switching capability at 48 VDC over its operating temperature range of 40°C to 130°C (104°F to 266°F).The operating temperature is preset at the factory and is non-adjustable in the field. The single pole/single throw switch assembly features a bimetallic element that is rated 100,000 cycles at 5 VDC 20mA resistive load.This unit features a positive snap action, available in either normallyclosed, open on rising temperature or normally open, close on rising temperature. The 6700 Thermostat dimensionally conforms to the international product package standard Y220/T0220. Thus, the 6700 may be automatically placed and soldered onto P.C. boards with high speed automated equipment, eliminating the need for the expensive hand placement and termination required today for most power supplythermostats. The nickel-plated copper mounting bracket allows this device to be directly mounted to the heat sink to sense an over-temperature condition caused by other components mounted close by or insufficient cooling due to external conditions. A plastic mounting bracket is utilized when VDE approval is required. Typical uses include turning on an indicator light, sounding an audible alarm,switching 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, and test equipment.
