LA-501MN

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. !External dimensions (Units : mm) 12.5 10° 1.25 1.25 φ1.25 !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. 7.4 (10.16) 3.5Min. 0.5 (2.54) 7.0 Tolerances are ±0.2 unless otherwise noted: !Selection guide Emitting color Red Common Anode Cathode ∗ Order-based production.
