| 6700 SERIES
TO-220, Subminiature Bimetal Disc Thermostat
Introduction
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.
Applications include computers and computer peripherals, aircraft,
automotive and test equipment. 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.
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
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.
