Panel Indicators, Pilot Lights

Panel indicators, pilot lights are important elements for monitoring machine or system performance. 1090QA3-28V is a type of panel indicator which consists of an LED indicator light, a soft push button, and a housing. The LED indicator will light up when the power is on and the soft push button will reset the indicator.

Application Field

1090QA3-28V is primarily used in industrial applications where reliable and immediate indication of status is required. The panel light indicator is suitable for many different applications which involve detection, monitoring and signalling. In the electronics industry, it is used in control panels, shelving displays, alarm systems and warning systems. 1090QA3-28V can also be commonplace in manufacturing and industrial machinery, giving users instantaneous visual confirmation that the system is running.

Working Principle

1090QA3-28V consists of an LED indicator light, a soft push button, and a housing. The LED indicator will light up when the power is on. It is lit by an independent circuit connected to a standardized voltage of 28V. When the circuit is left open, the LED will remain off. When the circuit is closed, the LED will turn on. This is also known as latching.

The soft push button is intended to reset the indicator. It does so by interrupting the power supply and the internal circuit is then re-opened. This will extinguish the LED until the circuit is re-closed and the power supply is restored.

Conclusion

1090QA3-28V is a reliable panel indicator light, suitable for many industrial applications. It is an easy to install and use component, which provides reliable and instantaneous visual confirmation. The LED indicator light will light up when the power is on and the soft push button will reset the indicator when needed.
