405-NWR120-NWO Application Field and Working Principle

Panel mount indicators and pilot lights can offer reliable and visible alarm signals, to indicate the process state of an input signal or an operating machinery. The 405-NWR120-NWO LED indicator is one of the most commonly used symbols for panel mount indicators and pilot lights. It is typically made of two components: a bulb and a signaling case. The bulb is the visible indicator, while the signaling case contains the electrical conductor to complete the circuit and power the bulb.

The application fields of the 405-NWR120-NWO can widely vary, including in residential and industrial settings. In a residential setting, it is often used in the form of a warning light, for example, to indicate the system is not running properly. Similarly, in industrial settings, this type of indicating device is often used as visual alarms, for example to indicate that certain processes are completed or in progress.

The common working principle of a panel mount indicator and pilot light is simple, yet straightforward. Their circuit is usually powered by DC voltage, and when the circuit is complete, the current will flow through the resistor and diode, generating a voltage drop over the LED. This will cause the indicator to become illuminated. In a warning light, this may also be accompanied by an audible alarm sound, if one is installed.

Clearly, the 405-NWR120-NWO offers secure and efficient alarm signals, that are applicable to a range of operating sites. To ensure functionality and long lifespan, this type of indicating device typically features a rugged construction, with a wide voltage range supply, and the capability to sustain a wide temperature range.
