RS046H Cryo Cooler
RS046H Split Integrated Dewar Cooler Assembly
Product Description
RS046H is a split version of RS046 rotary stirling cooler developed
by SensorMicro. With the same compressor structure of RS046, the
split format RS046H is even smaller in size.
The cold finger in RS046H dewar cooler has the same diameter as
that in RS046 cooler but with shorter length. Benefit from the
split design of the compressor and the cold finger, the infrared
system with RS046H integrated is flexible in special design. What's
more, the cooled detector itself is separated from the vibration
source, which enables the RS046H optimal in application requiring
better vibration and special conditions.
Due to its lightweight, miniaturization and low power consumption,
it is easier for the cryo cooler to be integrated into various
terminal products, which can greatly reduce the cost and meet
different customized needs of customers.

FAQs
1. What is a cryocooler used for?
Cryocoolers are machines that keep sensors extremely cold so that
thermal images can be taken on long-term missions. In many high-end
applications, the sensors that capture images require extremely low
temperatures.
2. What are the main factors to measure the quality of Cryocooler?
Long battery life and reliable operation are main factors to
measure the quality of a cryocooler. Our cryocooler has a wide
operating temperature range and excellent reliability. Its MTTF
(Mean Time to Failures) has reached to 10,000 hours, which meets
24*7 boot operation requirements.
3. What is MTTF?
MTTF (Mean Time to Failure) measures a part’s reliability. It shows
you how long on average a part lasts before it breaks and you have
to replace it. On a basic level, it tells you about the quality of
the parts you’re buying. The longer they last, the more value
you’re getting from them.
