LB-502VN

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. Dimensions (Unit: mm) 25.0 12.7 10˚ 1.25 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. 1.25 7.4 2−φ1.25 (20.32) Tolerances are ±0.2 unless otherwise noted : Selection guide Emitting color Red Common Anode LB-502VD LB-502DD ∗ LB-502DN ∗ LB-502MD LB-502MN Orange Green LB-502VN Cathode ∗ Order-based production.
