LEDs are one of the most popular forms of discrete indicators used in a variety of applications. The CMD91-21VRC/TR7 is an advanced, high reliability, long-life, triple-red-green-yellow 5mm LED indicator, which is suitable for all kinds of high-end, medium-high and medium-low discrete indicator applications. It has excellent performance characteristics under extreme temperatures, vibration, noise and other challenging environmental conditions.

The CMD91-21VRC/TR7 offers a wide range of benefits for applications, including reliable performance, superior visibility and superior vandalism-resistance. The CMD91-21VRC/TR7 is a highly efficient and reliable indicator, offering superior performance in terms of brightness and uniformity, even in challenging environments. It is capable of withstanding wide temperature ranges, from -40°C to +105°C. Additionally, its resistance to vibration, shocks, and electromagnetic interference make it an ideal choice for use in extreme and hazardous conditions.

The CMD91-21VRC/TR7 features three color LEDs in a 5mm plastic tube, allowing it to offer four color intensities of red, green, yellow and white. Each color has its own individual cathode, allowing them to be adjusted to different brightness and illumination levels. Additionally, the triple-lamp construction of the CMD91-21VRC/TR7 provides excellent insulation and heat dissipation, compared to many other discrete indicators.

The working principle of the CMD91-21VRC/TR7 is simple and easy to understand. When the LED indicator receives an AC power source, current flows through the cathode of the LED, eventually creating a light source when electrons are discharged. The intensity and color of the light depend on the amount of current and voltage supplied to the LED. Since each color is independent, they can be adjusted to specific brightness and illumination levels.

The CMD91-21VRC/TR7 LED Indication is suitable for a wide range of applications, ranging from industrial and medical instruments, outdoor sports and leisure equipment, traffic equipment and many more. Its high reliability under extreme environmental conditions, wide applications and easy-to-use design make it a versatile and cost-effective solution for applications requiring a discrete indicator.
