Panel Indicators, Pilot Lights – 464W-NKW2-NWO Application Field and Working PrinciplePanel indicators and pilot lights are used to indicate the status of electrical devices such as circuit breakers, contactors, switches, and power supplies. The indicator and pilot light models 464W-NKW2 and NWO are designed to show whether a device is energized and operating properly. This article will provide an overview of the application field and working principle of these two models.Application FieldThe 464W-NKW2 and NWO models of panel indicators and pilot lights can be used as indicators for both AC and DC applications. The 464W-NKW2 model is suitable for use with standard AC and DC power sources of up to 250 volts, and the NWO model is designed to handle higher voltage sources, up to 380 volts. These models are suitable for use in moderately explosive atmospheres, and can be used in a wide variety of applications, including residential, commercial, industrial, and military.Working PrincipleThe working principle of these panel indicators and pilot lights is based on the principle of positive temperature coefficient (PTC). When power is applied to the device, a heating element within the device causes the material surrounding it to expand, creating pressure which triggers a change in the device’s contacts. This, in turn, causes the indicator or pilot light to indicate whether the device is operating correctly.The 464W-NKW2 model features a carefully designed heating element to ensure that it can withstand temperatures up to 105°C, while the NWO model is designed to provide reliable performance in temperatures up to 150°C. Both models are designed for easy installation and maintenance, and feature rugged plastic enclosures to protect the internal components from dust and debris. These panel indicators and pilot lights can also be integrated with automated monitoring systems, allowing systems designers to monitor the status of the device, providing real-time feedback. This can provide peace of mind and prolong the life of the device by eliminating the need to manually monitor it on a regular basis.ConclusionPanel indicators and pilot lights such as the 464W-NKW2 and NWO models are a reliable and easy-to-use solution for monitoring the status of electrical devices. These models are designed to operate safely and reliably in both AC and DC applications, and feature rugged plastic enclosures to protect the internal components. They can also be integrated with an automated monitoring system to provide real-time feedback, eliminating the need for regular manual inspections.
