Panel indicators, lights, and enclosures are designed to provide cueing and environmental protection and to house electrical and electronic controls in a wide array of applications. The 3991A6-5V is a visual indicator that provides a bright, splash-proof unit for use in indoor, outdoor, and/or hazardous-rated environments. Suitable for use in industrial control panels, motor control centers, or machinery, this indicator features a wide variety of indicators, pilot lights, and enclosures.

The 3991A6-5V panel indicator is a lens-shaped indicator with an LED back-illuminated red signal. It is housed in a dielectric epoxy construction with self-cleaning contacts, ensuring optimal performance and maintenance-free operation. This panel indicator has been designed to meet UL 508 and UL 94V-3 standards, and has been UL-approved for use in hazardous areas including Class I, Division 2 areas of electrical control for industries such as oil and gas, chemical, and pharmaceutical plants.

The 3991A6-5V features a wide viewing angle of up to 170°, allowing direct visibility on the machine or from multiple angles. Its low-power consumption and low-profile design make it ideal for installation into tight spaces. The panel indicator also features an adjustable adjustment setscrew, allowing for simple and precise height adjustments. In addition, this panel indicator offers convenient mounting options, making it suitable for both horizontal and vertical mounting.

The 3991A6-5V panel indicator performs its signaling function by using a combination of round lighting elements and bright LEDs. The round lighting elements are arranged in a pattern to create a bright, evenly distributed signal. The LEDs flash in response to the changing signal, causing the indicator to blink. This blinking effect serves as a visual cue to alert operators or other personnel when a signal has changed.

The 3991A6-5V panel indicator is also equipped with a capacitor-protected internal power supply, which prevents the indicator from failing due to voltage fluctuations. This feature also ensures that the indicator is properly cooled and protected from dust and debris. The internal power supply also allows the indicator to cycle rapidly without losing luminance. The power consumption of the 389A6-5V is greatly reduced, which assists with energy efficiency.

In summary, the 3991A6-5V panel indicator is a bright, reliable, and energy-saving indicator light ideal for indoor and outdoor uses. With its wide viewing angle, adjustable mounting mechanism, and electric capacitor-protected power supply, it provides durable and long-lasting performance. Additionally, this panel indicator is compliant with UL 508 and UL 94V-3 standards for increased safety.
