LED Indication–Discrete: LTL-403HR Application Field and Working Principle

Light emitting diode (LED) technology is quickly becoming the dominate indicator light-source for most discrete retail, medical, industrial and general environmental applications. The LTL-403HR series is one of the most popular red LED light modules for these applications. In this article, we will discuss the application field and working principle of the LTL-403HR series.

Application Field

The LTL-403HR series are ideal for a variety of thermal (infrared sensing) and photoelectric sensing applications. The modules can be applied in electronic counters, time counters, security systems and warning systems among other fields. In addition, they are suitable for use in a variety of mounting configurations, including wall mount, surface mount, panel mount and other standard or custom mounting methods.

Working Principle

The LTL-403HR series module has three main components – an LED, a resistor, and a switch. When the switch is turned on, current passes through the LED, which lights up and provides a highly visible indication light. The LED brightness is adjustable through the on-board resistor, which can be adjusted to ensure the required light output. The module can also be used in a variety of voltage ranges, with a minimum working voltage of 3.0V and a maximum voltage of 30V.

Advantages of the LTL-403HR Series

There are many advantages to using the LTL-403HR series. The most notable is its long life span, which is typically much longer than other LED indicator models. This is due to its low power consumption, which helps to reduce heat buildup and thereby decrease the wear and tear on its components. Additionally, the module is designed to be highly reliable, with an IP65-rated enclosure that provides protection against dust and moisture. Additionally, the LTL-403HR series is also economical and cost-effective, as it offers excellent performance at an affordable price.

Conclusion

The LTL-403HR series of LED indicate modules is a reliable and efficient option for applications requiring discrete indication. The modules are suitable for a variety of applications and offer a long life span, low power consumption and a cost-effective solution. Additionally, the modules come in a range of mounting configurations and work in a variety of voltage conditions. With all these factors combined, the LTL-403HR series are ideal for use in many discrete indication applications.
