Panel Indicators, Pilot Lights

2170A59 is one among the several panel indicators and pilot lights used in the electrical industry. The device functions as a reliable visual warning that on the one hand, informs personnel for an important safety condition, and on the other hand, alerts technicians of unsafe conditions. This particular model is designed to be used in electronic equipment to indicate the presence of power on printed circuit boards.

Application Field

There is a variety of settings where 2170A59 be used in. Most typical applications involve the indicator of AC power, DC power, peak voltage, full-load capacity, malfunction, short-circuit, load shedding, and of heat detection. Generally, this device is suitable for industrial operations, equipment control, communications and computer transmitters, and many other situations where it is necessary to know when power from a certain circuit is active.

Working Principle

The working of 2170A59 is based on a simple operating mechanism, where the pilot light changes its color depending on the electric power that passes or is absent through the device. The unit design includes three main components: the housing, diffusion dome, and the LED.

The housing provides a sealed unit which contains two separate lead wires and two conductive terminals. The inner part includes the LED which is composed of an anode and a cathode. The two lead wires and the terminals are typically identified by red and black colors, which indicate the presence of current flow. The diffusion dome is a semi-transparent shield that helps to diffuse the LED shade and reduce blemish.

When power is applied into the device, the anode energy level activates the LED causing it to light up. The intensity of the light is proportional depending on the amount of electric current. On the other hand, when power supply is removed, the LED stops producing light.

Conclusion

The 2170A59 model is a reliable device that can be used in any application requiring visual warning of power supply and detection of safe or unsafe conditions. The fact that it is composed of a sealed unit, which contains housing, diffusion dome, and LED, makes it a great option for industrial operations and long term electrical safety. Also, the fact that the light color changes depending on whether there is power or not, help both personnel and technicians to know about any unsafe conditions.
