Discrete indicators have become indispensable to our daily lives. Whether it is machine status, communication network status, or operation environment monitoring, these indicators play a key role. Here we will talk about LNJ814K8SRA which belongs to Discrete LED indicator.

LNJ814K8SRA indicator is a three-pin high-intensity LED Indicator, which can replace the traditional two-pin indicator to reduce the installation cost. It is a form fitting design compatible with industry standard 3mm, 5mm, 10mm respective lens diameter lenses ensuring easy assembly and optical performance. With output voltages of 3V, 5V, 12V, 24V, it has superior performance in harsh environment when facing vibration, and extreme temperatures. The indicator’s mechanical design provides a longer operational lifetime compared to traditional designs. The BR (bright red) indicator allows the user to detect from further distances and with the highest accuracy even in the presence of sunlight.

LNJ814K8SRA indicators function best in environments requiring visually confirming that equipment has been activated, achives a given status, or indicates a fault without sound or vibration. Some of its application fields, for example, include:

• Medical Monitoring Systems.
• Electrical Movements.
• Telecommunication Networks.
• Control Panels.
• Industrial Automation.

As to the working principle, when high AC (DC) voltage applied, there will be a working current pass through LNJ814K8SRA indicator, then it will emit bright light. Meanwhile, a self-holding driving circuit is formed, which can maintain the light-on state even if the power is switched off. In order to turn off the LED, the LED must be reversed a certain voltage and current, which is higher than the value when the LED turned on. If the Voltage and current do not meet the requirement, the LED will not turn off. For this reason, we use a transistor as a switch to provide the reversed voltage and current in far away circumstance.

All in all, LNJ814K8SRA Indicator is an excellent choice in Discrete LED indicator with its compact size and wide applications, which can be used in very harsh environments when it comes to vibration and extreme temperatures. It provides easy assembly, low cost and reliable performance, that’s why it’s always been our preferred choice.
