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
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.
