KF3003-GL50A Printheads Thick Film Thermal Printhead (300DPI) KF3003-GL50A KF3003-GL50A is developing type of GL40 series which are developed mainly for label printers. 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 KF3003-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 2 and 4 inches. !External dimensions (Units : mm) TYPE OF PRINTHEAD 20.656±0.2 40±0.3 DOT #960 #1 HIROSE HIF3FC-20PA-2.54DS #20 #6 #1 #19 JST B6PS-VH Max.5.5 60.5±0.3 φ3H10 (Effective Depth 3) 20.5±0.3 17.8±0.2 7.3±0.3 Max.10 #2 15.3±0.3 φ2 0 (20.8) 25±0.5 20±0.3 (3) Max.36 Max.45 φ3H10 Length 4 (Effective Depth 3) (5) 81.312(Effetive Print Width) DOT #960 DOT #1 (4.844) 3-M3(Effective Depth 3) 6.1±0.4 91 KF3003-GL50A Printheads !Equivalent circuit DOT #960 VH DOT #1 GND 15 14 13 12 9 8 5 4 2 1 VDD STB4 64 OUTPUT EACH STB3 STB2 STB1 LAT LATCH REGISTER CLK SHIFT REGISTER SHIFT REGISTER SHIFT REGISTER DI4 DO4 DI3 DO3 DI2 DO2 DI1 DO1 TM THERMISTOR 30kΩ B : 3950 TM CONNECTOR DI No. DOT No. STB No. DOT No. DI1 1~256 STB1 1~256 DI2 257~512 STB2 257~512 DI3 513~768 STB3 513~768 DI4 769~960 STB4 769~960 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 DI3 3 VH 4 VDD 14 DO3 4 GND 5 STB4 15 DI2 5 GND 6 CLK 16 DO2 6 GND 7 DI4 17 STB2 8 DO4 18 STB1 9 STB3 19 DI1 10 LAT 20 DO1 SHIFT REGISTER KF3003-GL50A Printheads !Timing chart Min.30ns CLOCK (CLK) Min.10ns Min.30ns DATA IN (DI) "High" : BLACK "Low" : WHITE Max.120ns DATA OUT (DO) "High" : BLACK "Low" : WHITE Min.200ns Min.50ns LATCH (LAT) "High" : HOLD "Low" : THROUGH Min.100ns Min.300ns STROBE (STB) Max.10µs Max.10µs DRIVER OUT Fig.2 !Characteristics Parameter Symbol Typ.
