LB-502DN Series
LED displays
High efficiency, two-digit numeric displays
LB-502DN Series
The LB-502DN 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 13.0mm.
!Features
1) Height of character: 13.0mm
2) Common anode and common cathode configurations
are available for each color.
3) High efficiency reflectors are used to achieve a bright,
clear display.
4) The package surface is painted black and the
segments are colored the display color.
