LB-202BL Series LED displays High efficiency, two-digit numeric displays LB-202BL Series !External Dimensions (Units: mm) The LB-202BL series are small, two-digit numeric displays with a character height of 6.4 mm. These displays can be combined with appropriate displays in the three-digit LB-203 BL series to form a multi-digit display with an equal pitch interval between characters. 12.8 +0 −0.2 6.4 (12.2) 0.3 2−φ0.7 0.5 (2.54) (10.16) 7.9Min. +0 5.5 −0.2 0.7 3.4 +0 15.0 −0.2 0.7 !Features 1) Four colors are available: red, orange, yellow, and green. 2) Common anode and common cathode configurations are available. 3) Dynamic lighting system to minimize the number of pins. 4) The package surface is painted black and the segments are colored the display color. 6.4 10˚ Tolerances are ±0.3 unless otherwise noted : !Selection guide Emitting color Orange Red Yellow Green Common LB-202VB LB-202DB ∗ LB-202YB ∗ LB-202MB LB-202VL Cathode ∗ Order-based production.
