The DIALIGHT 552-3511 is a 5mm bi-color LED circuit board indicator designed for robust industrial applications. This indicator offers a red/green bi-color option, providing a third color (yellow-orange) when combined. Its common cathode configuration simplifies circuit design, while the diffused lens ensures even light distribution. The housing stand-offs facilitate PCB cleaning, and the LEDs are safe for direct viewing. Commonly used in panel indicators, annunciators, and other applications requiring visual feedback.
