Prime
LED bargraphs:
compact, high-density information displays
At just over one inch (26mm) in length, the BR-1326 26 tri-color segment 1mm pitch module is ideal for vertically-positioned applications in 1U high rackmount equipment. The 53 segment bargraph fits vertically within 2U equipment, with a height of 2.3 inches / 58mm. |
 |
| Both bargraphs are narrow enough to permit up to 24 vertically mounted bargraphs within a 19" rack panel. |
|
|
| All Prime LED bargraphs are
designed for easy mounting in slots on a panel, where the front (top) surface of the
segments is approximately flush (co-planar) with the front surface of the equipment panel
(or an optional bezel). This capability eliminates the design complexity and optical degradation of the transparent covering used in front of many conventional bargraph displays. |

electro-optical characteristics
all bargraphs have
been developed to provide a pleasing yellow (amber) color when both red and green LEDs are
active.
