LA-501DN Series
LED displays
High efficiency, single-digit numeric
displays
LA-501DN Series
The LA-501DN series were designed to meet
the need for 13mm single-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 single-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.
