Introduction to VLMK31R1S2-GS18VLMK31R1S2-GS18 is a part from a series of LED indicators, specifically categorized as discrete type. It is commonly used for system status feedback to provide visual cues, typically used to detect the current state of a system and indicating any changes that are made. Discrete LEDs, as compared to other types, is more cost-effective and suitable for applications with limited space.Application and FeaturesVLMK31R1S2-GS18 is designed to operate in industrial, medical and consumer environments. Its feature set includes a wide viewing angle, high-contrast indicator, high brightness output and an extended operating temperature range. Furthermore, VLMK31R1S2-GS18 has a rigid housing design which allows for easier integration in electronic devices and machines. The discrete indicator can be implemented in a variety of sizes and varying colors, from standard green to amber, yellow and white. It is useful for applications such as machine status, buttons, control panels, industrial automation and medical instruments. Its features also make it a good choice for replacing traditional incandescent indicators which consume lots of power, heat and produce minimal illumination.Working PrincipleVLMK31R1S2-GS18 works with a light emitting diode (LED) as the basic component. The LED is the source of light, converting electric energy into visible light. In a typical application, the LEDs are connected to a power source, such as an AC power supply, a DC bus or a switch, through a series of resistors and drive circuits. When the LED receives current, it emits a certain amount of light which is then filtered and collimated by a lens. The light output is then projected outward, illuminating the display surface. This light is controlled by the current passing through the LED and can be adjusted by varying the resistance in the circuit.ConclusionVLMK31R1S2-GS18 is a discrete LED indicator designed to operate in industrial, medical and consumer environments. It is designed to have a wide viewing angle, high brightness output and an extended operating temperature range. Its features make it an ideal choice for a variety of applications, such as machine status, buttons, control panels, industrial automation and medical instruments. It is also useful for replacing traditional indicators which consume more power and produce minimal illumination. It works with a LED as the basic component which converts electric energy into visible light, and is controlled by the current passing through the LED and can be adjusted by varying the resistance.
