2111A4 Optoelectronics

Panel Indicators, Pilot Lights

2111A4 is a panel indicator used for signaling purpose. Its design is straightforward and requires minimal technical know-how to install. It is an LED that can be used either as one or in a series of indicators. Its applications range from automotive signaling to machine status signaling.

The 2111A4 has an operating voltage range of 12 to 24 volts that can be powered from multiple sources like an AC/DC power supply or even a battery. It has a power draw rating of 1W and offers excellent performance in terms of brightness and energy efficiency. Its LED has an IP65 rating, which is suitable for use in both indoor and outdoor applications.

In terms of construction, the 2111A4 has a durable metal housing that will ensure its longevity. It is also designed to withstand environmental factors like dust, moisture, and temperature variations. In addition, its bezel is available in galvanized and stainless steel with different colors for distinguishing purposes.

The 2111A4 works on the basic principle of current flow through a circuit. An electrical current is supplied to the LED, and when the current reaches its threshold, the LED is lit up. The current is monitored, and when it drops below the threshold, the LED is turned off. The current flow can be adjusted by varying the voltage supplied to the LED.

In terms of applications, the 2111A4 is mainly used for signaling purposes. It is commonly used to indicate the status of machines, alarms, and warning systems. It can also be used in automotive systems to indicate various conditions like low voltage, oil temperature, and engine speed. It is also used in traffic signals, emergency systems, and home appliances.

In conclusion, the 2111A4 is a reliable and energy-efficient panel indicator that can be used for a variety of signaling applications. Its simple design and construction make it easy to install and its voltage range enables it to be powered from multiple sources. Additionally, its LED offers excellent performance in terms of brightness and energy efficiency.
