Temperature sensors come in many different forms and are used in many different fields, such as appliances, automotive, HVAC, medical, and industrial. Depending on the application different types of temperature sensing technology can be used. One type of temperature sensing technology is the 66L090-0394 thermal switch. This article will discuss the 66L090-0394 mechanical thermal switch and its application field and working principle.

Application Field

The 66L090-0394 series temperature switch is designed to withstand high temperature and high vibration environments. It is ideal for use in industrial and automotive applications which require a reliable, accurate and cost-effective temperature sensing solution. Common applications for this switch include automobiles, air conditioning systems, engines, and even medical equipment. The 66L090-0394 series is available in a variety of different body sizes, and is rated for a maximum operating temperature of 200°C. It is also UL, CUL, and CE compliant.

Working Principle

The 66L090-0394 series uses a mechanical thermal switch to detect temperature changes. The switch consists of a bimetallic strip, which is heated up by infrared radiation. When the temperature reaches the switch’s set point, the bimetallic strip deforms, allowing the contact points to make contact and trigger the switch. The 66L090-0394 series can be configured to open or close depending on the temperature.

The switch includes a thermostat and a switch mechanism in one compact package. The thermostat is adjustable, allowing the user to set the temperature at which the switch will trigger. The switch also includes a manual reset button, which allows the user to reset the switch once the temperature has returned to normal. The 66L090-0394 series is made from corrosion-resistant materials, ensuring a long-lasting product.

Conclusion

The 66L090-0394 series temperature switch is a reliable, accurate and cost-effective temperature sensing solution for a variety of industrial and automotive applications. The switch uses a mechanical thermal switch to detect temperature changes and can be configured to open or close depending on the temperature. The switch includes a thermostat and switch mechanism in one compact package, with a manual reset button for easy resetting. The switch is made from corrosion-resistant materials, ensuring a long-lasting product.
