High efficiency, two-digit numeric displays

LB-402DN Series

The LB-402 DN series were designed to meet the need for multi-digit numeric displays. These LED numeric displays use

GaAsP on GaP for the emitting material (with the exception of green) and are housed in an epoxy resin package. They are

two-digit displays with a character height of 10.16 mm.

Features Dimensions (Unit : mm)

1) Height of character : 10.16 mm

2) Common anode and common cathode

configurations are available for each color.

3) The package surface is painted black and

the segments are colored the display color.

4) High efficiency reflectors are used to

achieve a bright, clear display.
