Discrete LED indication solutions offer a variety of mounting and illumination options, providing a simple and cost-effective way of displaying status. The HSMN-A400-S8PM2 is an example of a typical discrete LED indicating product, and is increasingly used in a broad range of applications. In this article, we will discuss its application field, as well as its working principle.

Applications of HSMN-A400-S8PM2

The HSMN-A400-S8PM2 is a multi-colored indicator mounted on PCBs with a variety of operating voltages, from a few volts up to 60Vdc. It is offered in multiple colors and can be used for a wide range of applications, from industrial control systems to safety signaling, from medical equipment to consumer electronics. It is often used as an indicator for functional status, such as power-on, global positioning satellite (GSP) signal, and operating temperature.

The device is also often used in automotive applications, such as brake warning systems, power-on LED displays, and lighting-solution status, as well as in solid-state electromagnetic signal devices. It can also be used as an indication for charging and battery-level indication for both lead-acid and lithium-ion batteries.

Its compact and cost-effective design also makes it ideal for use in educational and office equipment, and has found application in escalators, vending machines, medical incubators and machines, motion sensor machinery, and game consoles.

Working Principle of HSMN-A400-S8PM2

The HSMN-A400-S8PM2 is a discrete, single-color LED indicator which can be either soldered or surface-mounted on a PCB. It uses two contacts: a + contact and a - contact. When the voltage between the two contacts is positive, the LED illuminates; when the voltage is negative, the LED will not light, regardless of the current applied.

The device utilizes a specialized 5.2mm profile housing. It requires a maximum of 20 mA current, and a working voltage between 2.8 and 60 Vdc. It can light to a maximum of 85 Lumens, depending on its color. The efficacy of the HSMN-A400-S8PM2 varies from 15 lumens/W to 200 lumens/W, depending on the color of the LED used.

The device is also statically certified for operation in a wide range of environmental conditions, from -40℃ to 105℃. It offers high immunity to EMC interference, and is rated IP67 for protection against water and dust.

Conclusion

The HSMN-A400-S8PM2 is a single-color LED indicator which offers a simple and cost-effective indication solution for a variety of applications. With its wide range of mounting and illumination options, as well as its static certification, it is ideally suited for use in industrial control, automotive, and medical applications. Its working principle is based on two connected terminals, and requires a maximum of 20 mA current and a voltage between 2.8 and 60 Vdc. It can light to a maximum of 85 Lumens, and its efficacy varies from 15 lumens/W to 200 lumens/W, depending on the color of the LED used.
