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 (5) (5.396) 54.208(Effetive Print Width) DOT #640 3-M3(Effective Depth 3) 6.1±0.4 65 φ3H10 Length 4 (Effective Depth 3) DOT #1 DOT #640 55.5±0.3 55±0.3 (20.8) 25±0.5 #2 #20 #4 #1 28±0.3 56±0.3 φ3H10 (Effective Depth 3) #1 HIROSE HIF3FC-20PA-2.54DS #19 JST B4PS-VH 15.3±0.3 7.3±0.3 Max.10 Max.5.5 17.8±0.2 φ2 0 (3) Max.36 Max.45 0.896±0.2 KF3002-GL50A Printheads !Equivalent circuit DOT #640 VH GND 10 9 DOT #1 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 THERMISTOR 30kΩ B : 3950 TM CONNECTOR DI No. DOT No. STB No. DOT No. DI1 1~320 STB1 1~320 DI2 321~640 STB2 321~640 Fig. 1 !Pin configuration CONNECTOR A CONNECTOR B No. Circuit No. Circuit No. Circuit 1 GND 11 TM 1 VH 2 VDD 12 TM 2 VH 3 GND 13 DI1 3 GND 4 VDD 14 DO1 4 GND 5 STB2 15 N.C. 6 CLK 16 N.C. 7 DI2 17 N.C. 8 DO2 18 N.C. 9 STB1 19 N.C. 10 LAT 20 N.C.
