High efficiency, single-digit numeric displays
LA-101AK Series
The LA-101AK series are LED numerical displays
designed to allow use even in bright locations. The
height of the character is 25.4 mm, and two colors are
available: red and green. These displays are designed
for use in large numerical displays.
!Features
1) Height of character: 25.4 mm
2) Dimensions: 24 x 34 x 10.5 mm
3) A common anode configuration and a common
cathode configuration are available for each color.
4) The package surface is painted black and the
segments are colored the display color.
5) High luminance, clear display.
