KD3002-DC10A printheads 1/4 thick film thermal printhead (300dpi) KD3002-DC10A KD3002-DC10A is developing type of gl40 series which are developed mainly for label printe rs. we have adopted low coefficient of abrasion and conductive protection coat to gl40 series which are possible for high speed and good printing quality. that is KD3002-DC10A which is 24v standard thick film thermal print head with high speed, high quality of printing, high durability, long life, and strong resistance to abration. z applications high speed label printer food label printer high speed ticket printer high speed terminal printer z features 1) perform 150km life time adopting new protective coat. (perform three times life time by coefficient of abrasion wh ich is about is about 1/10 of current mass-producing coat.) 2) build in thermal high speeded heater and perform high printing 4 ips. (100mm / s) 3) available for thermal transfer printing by adopting specific partial glaze.. z external dimensions (unit : mm) jst b4ps-vh hirose hif3fc-20pa-2.54ds dot #640 55 0.3 0.896 0.2 55.5 0.3 28 0.3 56 0.3 (20.8) 25 0.5 (effective depth 3) 3h10 (effective depth 3) 3h10 length 4 3-m3(effective depth 3) 7.3 0.3 15.3 0.3 17.8 0.2 max. 20 max.5.5 dot #1 (3) dot #640 (5.396) max.45 max.36 65 #1 #4 #19 #20 #2 #1 max.10 (5) 6.1?.4 type of printhead 54.208(effetive print width)
