The 6700 series temperature control switch is designed by Texas Instruments AIRPAX ® proprietary technology, and adopts the circuit board welding type. The JUC-31F series temperature control switch is a sudden-jump thermostat (in TO-220 package) with contact temperature sensing. Mainly there is a direct mounting bracket, so that the surface of the protector ideally conducts thermal sensing with the mounting area and the surrounding air. The shell is insulated, and the working performance is stable and the life is long. The product is sensitive and reliable in action, does not produce arcs, is easy to install, and has less radio interference. It is widely used in circuit boards, switching power supplies, chargers, ballasts and other fields.


[Model]: JUC-31F, 6700

[Temperature]: 30℃-150℃, one specification every 5℃, any temperature within the range can be provided according to customer requirements

[Features]: Small size, more flexible and convenient installation; Have stable working characteristics and excellent reliability;  Sensitive to temperature, fast movement speed; Flexible choice of connecting cable harness and nickel sheet

The working principle of 6700/JUC-31F
6700 adopts TO-220 package form. Sudden jump, single-pole/single-throw contact point of 100% conduction structure. When the outside temperature is too high, the bimetal that has been transferred to the corrected bimetal will act quickly. In this way, the circuit is cut off or connected (normally closed or normally open), and when the temperature drops to the reset temperature, the bimetallic strip is quickly reset, so that the quality is stable for a long time.

6700's competitive advantage
AIRPAX ® is one of the world's famous international brands that produce the most complete varieties of sensors and controllers and the largest output. Credit guarantee for product quality.
Strong thermal conductivity, mainly because of the direct mounting bracket, so that the surface of the protector ideally conducts thermal sensing with the mounting area and the surrounding air.
AIRPAX ® 6700 series is a miniature bimetal temperature control switch. Provide accurate and reliable thermal sensing and switching components with excellent repeatability
The size of the 6700 series temperature control switch conforms to the international standard product packaging Y220 / TO-220. Therefore, the 6700 can be automatically placed and soldered to the PC board using high-speed automation equipment.
AIRPAX ® 6700 series is suitable for PC boards with small space. Typical uses include alarming when the circuit is overheated or cutting off system power. Applications include computers and computer peripheral equipment, airplanes, automobiles, medical equipment and test equipment, power supplies, etc.
The 6700 series is hermetically sealed and can withstand wave soldering and cleaning actions
Pass safety certification: UL, CSA, VDE, CQC and comply with EU ROHS environmental protection requirements.
