| 6600 SERIES
8-Pin DIP, Subminiature Bimetal Disc Thermostat
OPERATION SCHEMATICS
Introduction
The Airpax® 6600 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 6600 series thermostat dimensionally conforms to the international product package standard 8-pin DIP (N8A Dual Inline Package). The 6600 is
ideally suited for use on printed circuit boards. Its size and shape conserves space on crowded PC boards and can be installed using auto-insertion
equipment. The device is sealed to withstand wave soldering and board washing operations.
The 6600 provides fast, positive response with excellent repeatability.
The thermostat has a switch capability of up to 1 amp for 48 VDC or 120
VAC, and achieves low-level switching down to 0.001 A to 0.020 A 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.
The 6600 thermostat is temperature tested in a computer controlled
automated test equipment air-oven. Due to the ideal conditions under
which it is tested, independent customer testing may be necessary to
ensure that the correct calibration is utilized in the application.
It is the customer’s responsibility to determine whether the product is
proper for customer’s use and application.

STANDARD TEMPERATURE CALIBRATION TABLE
Each thermostat part number consists of functional “building blocks” to
enable the user to specify clearly and precisely the desired characteristics
in each category. 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:
A 66F095 thermostat will close (make contact) on a rising temperature
from 90°C to 100°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.
Special requirements require a 4 digit manufacturing dash number for
ordering special features, 4 digit marking may not appear as part of the
marking on the thermostat.
Special requirements may include VDE, ±3.0°C (±5.4°F) operating
temperature tolerance, or surface mount (gullwing, SMT).
Temperature set point calibration is checked at Sensata Technologies
with precision test equipment traceable to the US National Institute
of Standards and Technology and Proven Methods. Because customer
checking methods may differ, a typical variance allowed for correlation
is ±1.1°C (±2.0°F).
