The DIALIGHT 552-3510F is a 5mm bi-color, bi-level LED circuit board indicator designed for various industrial applications. Its common cathode configuration simplifies circuit design, while the red/green LED provides a third color option (yellow-orange). The indicator features a high-contrast, UL 94 V-0 rated black housing, ensuring visibility and safety. Housing stand-offs facilitate PCB cleaning, and the LEDs are safe for direct viewing. Multiple units can be easily arranged in horizontal LED arrays on 7.62mm (0.300”) center-lines, making it suitable for panel indicators and status displays.
