Panel Indicators, Pilot Lights are types of devices used to visually indicate to users the status of equipment and when malfunctions are present. The APW199D-R-120V is one such device--a neon lamp indicator with a rectangular shape and visible in applications up to 2,000 feet away. The functions and use of such devices are various, but generally, they provide information on the status of equipment without using physical switches or relays.

APW199D-R-120V is a pilot light that can be used in a variety of applications. It is rated for 120 volts AC operation, with an average life rating of 10,000 hours when operated continuously. This high-intensity indicator is equipped with a bright and smooth-diffused lens that evenly disperses the light, making it highly visible in industrial lighting environments. It is available in a range of colors, including Green, White, Red, and Amber.

The APW199D-R-120V operates on the principle of a cathode-activated glow discharge. This is an electrical mechanism that causes the gas inside the bulb to form a luminescent plasma once it has been energized. This plasma is the source of the panel indicator or pilot light’s glow. When power is supplied to the device, electrons flow from the positive terminal to the negative terminal, causing the gas to ionize and create a glowing plasma.

As with any equipment and machinery, the APW199D-R-120V must be properly installed to ensure optimal performance and to protect it from damage. It is typically mounted on a panel or enclosure of the appropriate size and then wired to the load. The load should be suitable for the pilot light, with an operating voltage within 10% of the rating of the indicator. The wiring should be of a suitable type and gauge, and all connections should be properly insulated and secure.

APW199D-R-120V panel indicators and pilot lights are highly reliable and cost-effective. They offer high visibility, long-lasting operation, and easy installation. These features make them the perfect choice for applications that require continuous, easy to identify status messages. They are used in a variety of industries, including automotive, manufacturing, aerospace, and safety systems.
