Panel Indicators, Pilot Lights

Introduction: 305-NWW5H-O is a type of panel indicator, pilot light commonly used in electrical and electronic appliances. It is designed to be flush mounted on a panel, with waterproof rating IP67, which make it suitable for various applications, such as industrial machinery, domestic electrical appliances, signal systems, automotive applications, etc.

Application Field

The 305-NWW5H-O is widely used in various industries, mainly because of its waterproof IP67 rating. It is suitable for industrial machinery, domestic electrical appliances, signal systems,automotive applications, etc. It is compatible with DC/AC voltage of 12V/24V/110V/220V/380V.

In domestic electrical appliances, the indicator is often used to indicate on/off status of the device, and provide visual feedback to users. In industrial machinery, the indicator can serve as a warning alert to operators or maintainers. It can also be used in flashing mode, to convey dynamic parameters or warning signals to operators.

In signal systems, the indicator can provide reference signal for operators. For example, in railway signal system, the indicator can display different information, such as OK signal, halt signal, and warning signal. In automotive applications, it can serve as the indicator of car alarm system, to clearly indicate the status of the car.

Working Principle

The 305-NWW5H-O panel indicator works by turning on/off the LED light inside the indicator mechanism. The LED light is usually used as the light source. It is driven by a DC power source. By controlling the switch, the LED light can be turned on or off.

The indicator is usually equipped with an adjustable resistor, which can be used to control the brightness of the LED. Different type of resistors can be used, such as adjustable type resistors, or rheostat, or potentiometer. By adjusting the resistance value, the LED light can be made to light in different colors, such as green, red, amber, blue, etc.

The indicator is designed to be waterproof, thanks to its IP67 rating. It is made of special material that can resist harsh environment. It is also designed to be vibration-resistant, shock-resistant, and EMI-shielded, which make it suitable for industrial applications.

The indicator can also be equipped with an audio device. It can be used to emit different sound, like beeping alarm, or others. By using an external control circuit, the indicator can be set to emit sound under certain conditions, such as when the indicator turns on or off.

Conclusion

The 305-NWW5H-O is an IP67 waterproof and flush-mounted panel indicator, commonly used in electrical and electronics appliances. Its wide range of applications makes it a popular choice for many applications such as industrial machinery, domestic electrical appliances, signal systems, automotive applications, etc. It is driven by a DC power source, with adjustable resistor to control LED light brightness. Its waterproof, vibration-resist, shock-resistant and EMI-shielded design makes it suitable for industrial applications.
