5218268F: LED Indication - Discrete
LED indicators, or Light Emitting Diodes (LEDs), are semiconductor devices that produce visible light when an electrical current passes through them. They are widely used for indicating status and providing a visual reference for other equipment, such as electromechanical switches, variable speed motors, and even computers and other electronic devices. The 5218268F is a type of LED indicator that is used in direct connection applications. This article will discuss the application field and working principle of the 5218268F.
Application Field
The 5218268F is a general purpose LED indicator designed for direct connection application. It has a wide range of applications, from controlling the operation of appliances and providing visual indications on meters and instruments, to serving as an indicator of system performance and origin. This kind of LED can be used in a variety of systems, such as industrial equipment, computers, cell phones, automobiles, and consumer electronics. It is also suitable for use in hazardous areas, as it is designed to meet the requirements of most safety standards.
Working Principle
The 5218268F LED indicator operates on direct current (DC) electrical power. When a constant voltage is applied to the LED, an electrical current flows through the device and causes the LED to emit light. The intensity of the light emitted is proportional to the amount of current flowing through the LED. In order to ensure a constant luminescent flux and a uniform color, the LED must be used with a series resistor. The resistor limits the current to the LED, preventing it from burning out.
Most LED indicators have a two-wire connection, allowing for the use of two resistors in the circuit. The two resistors, known as Current Balancing Resistors, act as a series circuit to limit the current to the LED. The two resistors are connected in parallel, creating a voltage drop across each one that ensures that the same amount of current flows through each resistor. This allows for a steady and predictable light output.
The 5218268F LED indicator operates in two states: on and off. When the voltage applied to the LED is below the threshold voltage, the LED will remain off. When the voltage increases above the threshold voltage, the LED will turn on. This characteristic makes the 5218268F suitable for a variety of indicator applications, such as indicating the status of a system or providing a visual signal of a process or operation.
The 5218268F LED indicator is designed for robust and reliable operation. It is constructed with a durable main body that is resistant to electric shock, moisture, and environmental variations. The LED indicator is also designed to withstand a wide range of temperatures, from -55°C to +125°C. This ensures that the LED indicator will remain operational in a variety of conditions.
Conclusion
The 5218268F LED indicator is a versatile and reliable device that can be used in a variety of applications. The indicator operates on direct current and has a two-wire connection, allowing for the use of two resistor in the circuit. Its durable construction and temperature resistance make it suitable for use in hazardous or extreme environments. Additionally, the indicator is capable of providing a noticeable visual indication when it is turned on, allowing for easy detection and monitoring of system activity.
