Engineering Use
Built for Clear Machine Status Indication
LED indicator arrays are used when engineers need several visible signal points in a compact, repeatable mechanical format. Instead of placing several separate lamps on the PCB, the integrated black housing keeps the LED positions aligned and gives panel builders a cleaner front-view appearance.
The 3mm lamp format is suitable for red, yellow, green, purple and blue status indication. Typical use cases include power, run, fault, communication, charging, alarm and mode indication in export-oriented equipment. Color combinations can be selected according to customer logic and panel labeling.
