NL177WL2G is a panel indicator with built-in Light Emitting Diode (LED) lighting, suitable to be mounted on the bottom or panel of meters, instruments, electrical products, control boxes etc. This panel indicator is typically used to signal and show on-off conditions of power outputs or inputs, sound alarms, display problems, and answer operations. The NL177WL2G is available in two housing types: the flush-mount type (IP40 protection grade) and the box-mount type (IP54 protection grade).

The housing of the NL177WL2G is made from aluminum alloy, making it lightweight and capable of withstanding various environments. The indicator’s surface is treated using nickel-plating, giving it excellent dustproof and waterproof capabilities. It has a simple surface, which makes it easy to mount and clean. In addition, the NL177WL2G has excellent heat dispersion capabilities, ensuring a low temperature rise even when the indicator is operating for extended periods of time.

The NL177WL2G operates on a rated voltage of 12V to 220V AC/DC, allowing it to be widely used in different applications. The indicator is capable of working in temperatures ranging from -40 degrees Celsius to +40 degrees Celsius, and its humidity range is 5% to 80% RH, ensuring it can operate well under various conditions. The NL177WL2G has a long lifespan of over 30,000 hours due to its LED lights, as LEDs use very little energy and are very durable.

Pilot lights are electrical indicators that are used mainly to give visual indication of a machine, appliance, or process. They can be used for a variety of applications such as on/off indication, alarm indication, and communication that something is happening. They are often found in places with a high level of activity such as control panels and consumer products. Pilot lights are commonly identified by their characteristic lens shape and color, usually signifying their purpose.

Pilot lights are usually composed of a lamp and a colored glass cover. The lamp is usually a light bulb or a neon lamp. It is connected to a power source and will light up when power is applied. The colored glass cover is used to identify the purpose of the light and to also protect the lamp from dust and moisture. Pilot lights come in many colors, including red, green, yellow, blue, and orange. They can also be found in other colors depending on the application.

The working principle of the NL177WL2G is relatively simple. When the power line is connected to the indicator, current flows through the LED and illuminates the indicator. The intensity of the light can be adjusted depending on the current supplied to the LED, allowing customers to manipulate the indicator’s brightness. This makes the NL177WL2G ideal for applications where a dimmer LED is needed to save energy and prolong its life.

The NL177WL2G is one of the most widely used panel indicators due to its simple design and long life. Its LED lighting and adjustable brightness make it ideal for many applications, ranging from on/off indication to sound alarms and display problems. With its robust aluminum alloy body and nickel-plating, the NL177WL2G is dustproof and waterproof, and suitable to be used in various environments. The NL177WL2G is a great solution for any application that requires an efficient, long-lasting, and reliable panel indicator.
