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.
