F20B11505ACFA06E application field and working principle

Temperature Sensors - Thermostats - Mechanical

The F20B11505ACFA06E is a temperature sensor made by Fujitsu that conforms to the double side bi-metal snap-acting thermostat standard. It is designed as a digital circuit breaker or backup switch, and has a controlled area of up to 6mm2 for higher and lower temperature operations, which can operate up to 250°C. The F20B11505ACFA06E uses a two-stage thermal insulation to maintain a high precision temperature control range from -40°C to +250°C.

The working principle of this temperature sensor is based on the bi-metal rectification principle. It consists of two metal plates—a bi-metallic contact element and a stationary contact element—which are firmly set on a single piece of plastic material. When an external temperature change occurs, the bi-metal will bend and the stationary contact will touch the moving contact to actuate the switch. When the external temperature changes back, the bi-metal material will regain its original shape and the switch will return to its original position.

The F20B11505ACFA06E is mainly used in automotive, industrial, and home applications. It can be used for temperature controlling applications, such as in cars to prevent overheating, or in appliances like water heaters and air conditioners to calculate and control the temperature at all times. This temperature sensor is also used in medical equipment, like incubators, to maintain steady temperatures for newborns. Additionally, it can be used to control heating and cooling mechanisms in buildings to regulate the amount of heat and cool air in the space.

Furthermore, the F20B11505ACFA06E is designed with a variety of features for optimal performance and reliability. It is designed with a temperature precision tolerance of ±2°C, as well as a low-power thermal control, self-locking switch design, and a long service life. Additionally, this temperature sensor has a single-pole double-throw snap-acting mechanism, which ensures a reliable mechanism for a wide range of applications.

In conclusion, the F20B11505ACFA06E is a versatile and reliable temperature sensor that is designed to provide accuracy and reliability in a variety of applications, from automobiles to medical equipment. With its two-stage thermal insulation and single-pole double-throw snap-acting mechanism, it can provide high precision temperature control with a minimum of power consumption. It is suitable for a wide range of applications and can be trusted for long-term reliable performance.
