LED Indication – Discrete

LED indications are used in many different applications and vary in technical features. In this classification of LED indicators, the CMDA2DR7A1W LED discrete refers to an LED that is used for the purpose of indicating, rather than for general illumination or backlighting. This type of LED often has two large terminals marked “+” and “-”. The ring-shaped body 1.2mm is made of epoxy and contains a single GaAsP semiconductor. The emission wavelength emitted is visible red, and the configuration of the LED package allows the user to observe light is at only one angle.

The application of CMDA2DR7A1W LED discrete is usually used for commercial alarm systems and industrial machine status indicators. It is the perfect choice when you need to indicate system device access and security, emergency lighting, machine control and warning of machine errors. Its working principle is simple – when an alternating current is applied to the LED, electrons move between the semiconductor and the P-type silicon, emitting red light from the N-type silicon. This red light then illuminates the area in which the LED is located.

The main advantages of using CMDA2DR7A1W LED discrete are its long term reliability and low power consumption. At a working current of 20mA, the CMDA2DR7A1W LED emits a luminous intensity of 7mcd and is visible from distances up to 3m away in an unlighted room. The device has also been designed to maintain consistent brightness even when temperature or vibrations are applied to it. The outer surface of the LED is resistant to wear and tear, making it suitable for long term use. Moreover, the LED’s power consumption is very low at 0.25W, making it an energy efficient choice.

Generally speaking, the CMDA2DR7A1W LED discrete is an ideal LED indicator for commercial and industrial applications, where a clear signal of machine status and system access is necessary. It has excellent performance in terms of luminous intensity and its long term reliability makes it a cost-effective choice. As a discrete LED, its size is especially suitable for applications where space is limited.
