LED Indication - Discrete

CMD15-21VYD/TR8 is a type of LED that is designed for use in discrete indicator applications. The major advantage of this device is that it can be used with a wide range of input voltages, so it’s a great choice for many industrial applications. The design of this device includes an internal series-wired Zener diode, which allows it to be used with input voltages of up to 21V DC.

Application Field

CMD15-21VYD/TR8 LEDs are often used in small-scale industrial applications, such as in small control panels and assemblies. They are often used to indicate the on/off state of a piece of equipment, such as a starter switch. In addition, these LEDs can be used in a machine’s control panel to indicate whether the machine is in normal or alarm state. This device can also be used in automotive and transportation applications, as it can function in a wide range of input voltages, from 9V to 21V.

Working Principle

CMD15-21VYD/TR8 LEDs work on a simple principle. When a voltage difference is applied across two terminals, electrons flow from one terminal to another, generating energy in the form of light. This light is then emitted from the LED chip, resulting in a steady and consistent light output. In addition, the LED chip is embedded in a protective lens that prevents dust and dirt from entering the device.

CMD15-21VYD/TR8 LEDs are designed to offer a longer lifetime than traditional LED indicators. This is achieved through the use of an internal series-wired Zener diode which helps to reduce the current surge when the appliance is switched on, which can often damage traditional LEDs. In addition, the LED is designed with a reverse voltage protection feature which prevents the device from malfunctioning when the input voltage is reversed.

The major advantage of CMD15-21VYD/TR8 LEDs is that they can operate in a wide range of temperature and environmental conditions. They are rated to operate in a temperature range of -20C to 70C and can survive temperatures up to 85C. In addition, they are designed with a reverse polarity protection feature which prevents the device from malfunctioning when the input voltage is reversed, thus offering enhanced safety and reliability.

Conclusion

CMD15-21VYD/TR8 LEDs are designed for use in discrete indicator applications, specifically for use in small-scale industrial applications. They offer a long lifetime and are designed to withstand a wide range of temperatures and environmental conditions. They provide a reliable, consistent and efficient means of indicating the on/off state of equipment, as well as warning of any potential alarms.
