VLMS30K1L2-GS18

LED indicators are widely adopted in various fields, from home decorating to industrial products. This article will cover the application field and working principle of one of the most common LED indicators: VLMS30K1L2-GS18.

The LED indicator is mainly for discrete applications, including field automation and factory automation. Its miniature size and simplicity makes it often used in the PLC installation of factory automation stations. Due to its bright illumination, it can be used as a warning lighting in alarm systems.

The VLMS30K1L2-GS18 indicator has a miniature 8.5mm by 8.5mm size, ensuring that it won’t take too much space and can fit into a wide range of applications. It is illuminated by a high-power LED, giving the highest contrast between on-light and off-light states. All the LED indicators have an embedded optical lens and diffuser, which provides the best angle of view and consistent brightness across the entire viewing area.

The indicator is designed to be operated between 12V and 28V, making it suitable for direct connection to most of the common field controllers. Its nominal output power is 0.2W and its current consumption is about 21mA, which is quite impressive considering its 8.5mm miniature size.

As for the working principle of the LED indicator, it is quite straightforward. It is powered by a DC voltage source and it has a built-in current-limiting resistor (at 100 ohms), ensuring a constant current supply. When voltage is supplied, the diode emits light, otherwise it is off. The internal resistor prevents any over-voltage situation, making it robust and reliable.

VLMS30K1L2-GS18 LED indicator is an extremely versatile solution for discrete applications. Its miniature size, high-power LED, wide operating voltage range, and robust structure make it a perfect choice for any application that requires a discrete indicator. With its impressive current draw of only 21mA, this LED is also quite energy-efficient.
