Panel Indicators, Pilot Lights,

The 2390QD4-28V is a versatile panel indicator, great for a variety of applications due to its small size and resistance to shock and vibration. It works by emitting a steady light when in use, which makes it the perfect solution for cost-effective alerting. In this article, we’ll take a look at the application field and working principle of the 2390QD4-28V.

ApplicationField

The 2390QD4-28V is a versatile panel indicator, suitable for a variety of industrial and commercial applications. It can be used to indicate the status of a machine or system with its steady light. It is often used in control panels of industrial machines, emergency power systems, home automation systems, consumer electronics, and process control systems to name a few. The small size of the 2390QD4-28V makes it ideal for use in confined areas, making it a reliable and cost-effective solution for alerting.

WorkingPrinciple

The 2390QD4-28V panel indicator uses two electrodes attached to the base of the indicator which serve as a means of conducting electricity from the connected power source through the electrodes to the indicator’s filament. The filament is then heated and the panel indicator will emit a steady light once current passes through the filament. The indicator has a high resistance to shock and vibration, making it ideal for use in hazardous or rugged environments.

This panel indicator also has enhanced durability due to the construction of the filament, which is surrounded by a boron nitride coating. The boron nitride coating helps to protect the filament from excessive heat, which can cause it to break or expand. This ensures that the indicator will perform without interruption. Additionally, the 2390QD4-28V has a long-life design that can withstand millions of operations.

Conclusion

The 2390QD4-28V panel indicator is a versatile and reliable solution for a variety of applications, from industrial machines to process control systems. It is designed to withstand shock and vibration and has an enhanced durability due to its construction. Additionally, it has a long-life design that can withstand millions of operations. All of these features make the 2390QD4-28V the perfect solution for cost-effective alerting.
