551 Series, Circuit Board Indicators, Arrays, Light Bars, Bar Graphs

The LED devices in this product family are specifically designed as visual indicators and offer a wide range of formats for convenient usage. These devices, commonly referred to as Light Emitting Diodes (LEDs), serve as reliable indicators to convey important information in numerous applications. At the simplest level, single LEDs are frequently employed to indicate the power-on status of electronic devices. By emitting light when powered, these LEDs provide a clear visual indication that the device is operational or in standby mode. Moving beyond single LEDs, there are multi-segment devices available within this product family. These devices feature multiple LED segments arranged in a linear or segmented format, resembling a bar graph display. This configuration is particularly useful for visually representing data such as fluid levels in tanks or the remaining charge in batteries. Each segment of the LED bar graph corresponds to a specific level or value, allowing users to quickly and easily interpret the information presented. The packaging of these LED devices is designed with convenience in mind, making them easy to integrate into various applications. These devices are available in different sizes, shapes, and mounting options to meet diverse requirements. Common examples include through-hole packages for easy soldering onto circuit boards, surface mount packages for compact and space-efficient designs, and panel-mounted configurations for straightforward installation on control panels or equipment. In summary, the LED devices in this product family serve as visual indicators and come in various formats to suit different application needs. They range from single LEDs used for power-on status indication to multi-segment devices resembling bar graph displays, capable of communicating information such as fluid levels or battery charge. The packaging options ensure convenience and compatibility with different mounting methods, enabling seamless integration into a wide range of electronic devices and systems.
