SA52-11SRWA Application Field and Working Principle

The SA52-11SRWA is a seven-segment device from CHIMEI Corporation, and a type of LED display module from Display Modules - LED Character and Numeric category. The SA52-11SRWA is a versatile display module with features suitable for an assortment of functions. In this article, we will discuss the application field of the SA52-11SRWA, and its working principle.

Application Field of SA52-11SRWA

The SA52-11SRWA is an LED display module, wherein each digit is composed of seven segments with seven LED elements. It has a wire wrapped crimp connecting socket, making broadband communication with microcomputer systems possible. Its features fit a number of applications, including scientific instruments/equipment operations, intelligent control systems and factory automation, as well as personal computers and other digital equipment.

Working Principle of SA52-11SRWA

The SA52-11SRWA LED digit display module is an active device that has seven LED elements per digit. The LED elements are designed so that their colors appear to be the same from viewing at any angle. The LED elements are divided into four main sections - the display gap, the cathode section, the anode section and the sensing section. The anode section and the cathode section contain seven serially connected LEDs, while the display gap section contains several current limiting resistors. The sensing section has one analog semiconductor or optoelectric sensor.

The SA52-11SRWA LED digit display module is powered by a power supply, and works by allowing electrons to flow from the + side to the – side of the display gap section. Electrons can flow through the display gap section due to the resistance limited by the current limiting resistors. Once electrons pass through the display gap section and reach the anode section, they can light up one of the seven LEDs in that section. The seven LEDs in the cathode section will also light up if the same current is applied to them. Once these LEDs are all lit, the module is ready to display the assigned number.

The SA52-11SRWA LED digit display module also has a unique option to adjust the brightness of the LEDs. It uses the optoelectric sensor in the sensing section to detect the ambient light environment, and then adjusts the brightness of the LEDs accordingly. This makes it possible to display clear data even in an environment with low light levels.

Conclusion

In summary, the SA52-11SRWA is a type of LED display module from Display Modules - LED Character and Numeric category, and it has many features suitable for a variety of applications, such as scientific instruments/equipment operations, intelligent control systems and factory automation, as well as personal computers and other digital equipment. It works by allowing electrons to flow from the + side to the – side of the display gap section and through the anode section, which will light up one of the seven LEDs in that section. It also has a unique option to adjust the brightness of the LEDs to present clear data even in low light levels.
