KF3002-GL50A

KF3002-GL50A Printheads Thick Film Thermal Printhead (300DPI) KF3002-GL50A KF3002-GL50A 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 KF3002-GL50A 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. !Applications High speed label printer Food label printer High speed ticket printer High speed terminal printer !Features 1) Perform 150km life time adopting new protective coat. (Perform three times life time by coefficient of abrasion which is about is about 1/10 of current mass-producing coat.) 2) Build in thermal high speeded heater and perform high printing 6 IPS. (150mm / s) 3) Available for thermal transfer printing by adopting specific partial glaze. 4) Use the structure of thermal G-series which had good actual results. And these good results will guarantee high reliability of GL-series. 5) Line-up for 3 and 4 inches. !External dimensions (Units : mm) TYPE OF PRINTHEAD 65 (5.396) 54.208(Effetive Print Width) 6.1±0.4 (5) DOT #1 φ3H10 Length 4 3-M3(Effective Depth 3) (Effective Depth 3) DOT #640 55.5±0.3 55±0.3 0.896±0.2 DOT #640 25±0.5 Max.45 Max.36 φ2 0 (20.8) (3) 15.3±0.3 7.3±0.3 Max.10 #2 #20 #4 #1 Max.5.5 56±0.3 28±0.3 φ3H10 (Effective Depth 3) #1 #19 HIROSE HIF3FC-20PA-2.54DS JST B4PS-VH 17.8±0.2 KF3002-GL50A Printheads !Equivalent circuit VH DOT #640 DOT #1 GND 10 9 8 7 6 5 4 3 2 1 VDD 64 OUTPUT EACH STB2 STB1 LAT LATCH REGISTER CLK SHIFT REGISTER SHIFT REGISTER DI2 DO2 DI1 DO1 TM TM CONNECTOR THERMISTOR 30kΩ B : 3950 DI No. DI1 DI2 DOT No. 1~320 321~640 STB No. STB1 STB2 DOT No. 1~320 321~640 Fig. 1 !Pin configuration CONNECTOR A No. 1 2 3 4 5 6 7 8 9 10 Circuit No. Circuit CONNECTOR B No. 1 2 3 4 Circuit VH VH GND VDD GND VDD STB2 11 12 13 14 15 16 17 18 19 20 TM TM DI1 DO1 N.C.
