Panel Indicators, Pilot Lights

2111QA4 is a series of panel indicators, which are used to identify the working status of industrial boards, panels, and equipment. It adopts a unique design, enclosure structure, sealed structure and flexible LED circuit connection method, which makes it easy to install and use.

Features of 2111QA4

The features of 2111QA4 can be divided into two aspects: electrical properties and mechanical properties.

Electrical Properties:

1. Equipped with ultra-thick copper materials, the input voltage can range from 8-36V DC or 12-80V AC. 2. LED indicators can be used to indicate various status, including On, Off, Working and Error conditions. 3. Mounting screws are provided to make sure that the indicator is not easy to detach and can be fixed firmly on the panel.

Mechanical Properties:

1. The high voltage resistance and current resistance material of the enclosure ensures that the indicator is free from short-circuit and other adverse circumstances. 2. The front panel is clear for easy identification and is textured for added protection from scratching and wear and tear. 3. The contacts are plated with gold to increase the contact resistance and increase the reliability of the device.

Working Principle of 2111QA4

The working principle of the 2111QA4 is based on the ability of the LED to emit light when a current passes through it. When two wires or leads are connected to a circuit, a current will pass through the LED, and the LED will light up. Depending on the polarity of the connection, different colors can be emitted from the LED. The flexible LED circuit allows for two colors to be connected together, such as red and green. Depending on the order of the connections, different colors can be produced.For instance, the red LED can indicate that the circuit board or device is in the On position, while the green LED indicates the Off position. Alternatively, the red LED can be used to indicate that an Error is present, while the green LED indicates that the circuit is in the Working position.

Applications of 2111QA4

2111QA4 is widely used in the following industries:1. Automotive industry: 2111QA4 is used to indicate the running status of the automotive system, such as engine start/stop, warning status etc. 2. Telecommunications industry: It is used to indicate the status of switches, routers, and other electrical equipment. 3. Industrial industry: It is used to indicate the operation state and running speed of various machinery. 4. Medical equipment: It is used to monitor the working status of medical equipment, such as valves, pumps, medical monitoring systems, etc. In conclusion, the 2111QA4 panel indicators and pilot lights are an excellent choice for a wide variety of applications in the automotive, telecommunications, industrial, and medical industries. The unique design, enclosure structure, sealed structure, and flexible LED circuit connection make it a reliable and easy to install choice. The electrical and mechanical properties of the 2111QA4 work together to ensure that the device is reliable and durable. Additionally, the color-coded LED indicators make it easy to identify different working statuses.
