553 & 571 Bi-Level Circuit Board Indicators

Dialight 553 and 571 Bi-Level Circuit Board Indicators (CBI) are offered in 2mm and 3mm packages, with two diode LED indicators each, and in several color combinations. The 553 series includes 3mm LEDs in 2x red, 2x yellow, 2x green, red/green, and yellow/green. 553-x multiple CBIs form horizontal LED arrays on 4.45mm center-lines, and 553-x-300 multiple CBIs form horizontal LED arrays on 5.08mm center-lines. The 571 series includes 2mm LEDs in 2x green, red/green, and yellow/green. Multiple CBIs form horizontal LED arrays on 2.54mm center lines. All of the Dialight 553/571 Bi-Level Circuit Board Indicators come in high contrast, UL 94V-0 rated black housing with stand-offs that facilitate PCB cleaning.
