TO-220, Subminiature Bimetal Disc Thermostat
FEATURES
• RoHS compliant per EU directive 2002 / 95 / EC
• TO-220 / Y-220 international electronic package standard
• Ideal for surface and air sensing on PC boards and heat sinks
• VDE approved with “P” bracket option
• Gold-plated contacts
• Up to 20,000 life cycles @ max standard amperage
• Up to 100,000 life cycles @ max gold contact amperage
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.

STANDARD TEMPERATURE CALIBRATION TABLE
Each thermostat part number consists of functional “building
blocks” to enable the user to specify the desired characteristics.
Select the proper code in each category, then transfer it to the
box indicated. Unless a special requirement is indicated, the part
number will be complete when the proper temperature is selected.
If you have a special requirement, please call Sensata for a factory
assigned number to complete the part number.
Example 1:
A 67F090 thermostat will close (make contact) on a rising
temperature from 85°C to 95°C and will reset open (break contact)
on a falling temperature within a window of no greater than 6°C
lower than the actual close temperature and no less than 60°C
ambient temperature.
Example 2:
A 67L060P thermostat has a plastic mounting bracket with 2000
VAC dielectric strength and VDE approval.The thermostat will open
(break contact) on a rising temperature from 55°C to 65°C and will
reset close (make contact) on a falling temperature within a window
of no greater than 4°C lower than the actual open temperature and
no less than 40°C ambient temperature.
The mounting bracket designation and the 4 digit manufacturing
dash number are used for ordering special features and may not
appear as part of the marking on the thermostat.
Temperature set point calibration is checked at Sensata
Technologies with precision test equipment and proven methods.
Because customer checking methods may differ, a typical variance
allowed for correlation is ±1°C.
