The Airpax™ 6700 series of positive snap-action, single-pole / single-throw, sub-miniature bimetallic thermostats provides accurate and reliable sensing and switching in a single device.
Housed in a standard TO220/Y220 package, the 6700 series thermostats are compatible with high-speed automatic placement and soldering onto PC boards. This eliminates the manual placement and termination required by most power-supply thermostats.
The 6700 series provides fast, positive response with excellent repeatability. The switch capability of up to 0.5A for 48 VDC achieves low-level switching down to 0.001A to 0.020A at 5 VDC for 100,000 cycles. The temperature is pre-set at the factory and is non-adjustable in the field.
Thermal conductivity through the terminals and the mounting bracket makes these thermostats suitable for surface-mount and ambient air sensing. The standard device offers a nickel-plated copper mounting bracket whilst a laminated plastic mounting bracket can be used for increased dielectric strength and VDE approval.
The Airpax™ 6700 series are typically used for thermal management on power supplies, particularly on high-density PC boards in aircraft, automotive, medical devices and test equipment. Applications for the 6700 series include turning on an indicator light, sounding an audible alarm, switching on a control circuit to send a message to a display screen or switching a circuit to shut-down a system.
