lb-202bl series led displays high efficiency, two-digit numeric displays lb-202bl series 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. ! 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. ! ! ! ! external dimensions (units: mm) tolerances are ?.3 unless otherwise noted : 0.7 3.4 2 ? 0.7 0.7 6.4 6.4 15.0 10? 12.8 ? 0.2 + 0 0.3 (12.2) 0.5 (2.54) (10.16) 5.5 7.9min. + 0 ? 0.2 + 0 ? 0.2 ! ! ! ! selection guide emitting color common anode cathode red lb-202vb lb-202vl orange lb-202db ? lb-202dl ? yellow LB-202YB ? la-202yl ? ? order-based production. green lb-202mb lb-202ml ! ! ! ! pin assignments pin no. dig.1 dig.2 109876 +++++ 1 2345 + ++++ a g d f b e c a g d f b e c digit 1 common segment "e" segment "d" segment "c" d.p digit 2 common segment "g" segment "b" segment "a" segment "f" 1 2 3 4 5 6 7 8 9 10 function pin no.
