| 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 automaticallyplaced 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 0.010A 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 anindicator light, sounding an audible alarm, switch on a control circuit tosend 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 airsensing. 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 tosend 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.

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

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 codein 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 awindow of no greater than 6°C lower than the actual close temperature and noless than 60°C ambient temperature.

Example 2:A 67L060P thermostat has a plastic mounting bracket with 2000 VAC dielectricstrength and VDE approval.The thermostat will open (break contact) on a risingtemperature 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 areused 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.
