LED Indication - Discrete

Light Emitting Diodes (LEDs) are widely used in diverse applications to indicate status of machinery, guides whether inspection check points have been completed, and to mark locations on creative and labelling systems. To make application of an LED more efficient, multi-use LED’s are created and designed for combined use in different types of operations. One type is the 521, 9498F LED.

These LED’s are capable of such diverse service because they can operate in multiple types of circuits. These durable LED’s are made from a polycarbonate based package with an all-metal housing added. The polycarbonate package houses a series of light emitting elements that is covered by an epoxy-resin lens. The metal housing provides excellent shock and vibration protection.

The 521, 9498F LED is a two-wire connection device with a rated current of 2.5 miliamps up to 2.0 volts. This makes the device ideal for use in AC circuits, DC circuits, and with constant current or constant voltage control systems. Additionally, they can be operated as part of non-isolated switching circuits, as part of an independent system, or as part of a time-delay circuit.

The main feature of the 521, 9498F LED is the integral double diode included in the package. This allows the LED to be used in both AC and DC circuits simultaneously and without fear of corrosion or malfunction. The double diode is also able to connect and disconnect the load without active components, allowing the LED to be driven continuously without the need for active components and without risk of damage.

Another feature of the 521, 9498F LED is the active bi-stable element, which dissociates the switching and the current control functions. This allows the current control to be adjusted independently, adjusting and stabilizing the current going to the LED, making it an excellent choice for switching control applications.

The 521, 9498F LED is also suitable for use in high and low current applications due to its low-power requirement, making it an ideal choice for both on and off-premise displays. Additionally, it is designed to meet both IEC and UL standards for safety, providing an additional layer of compliance when used in high temperature environments.

The versatile 521, 9498F LED is a great tool for engineers who need to design LED indication systems. With its built in double diode and bi-stable element, this LED provides a great deal of flexibility when designing circuits. Additionally, its security and certification standards make it an excellent choice for any type of circuit.
