KF2002-GL50A Printheads Thick film thermal printhead (8 dots / mm) KF2002-GL50A The KF2002-GL50A is a 24 V standard thick film thermal printhead with a printing speed up to 6 inches / s that has been developed mainly for label printer use. zApplications High speed label printer High speed bar code printer High speed ticket printer Various high speed terminal printers zFeatures 1) Newly developed thick-film fast response thermal element is employed for this series and 6 inches / s or 150 mm / s is possible without thermal history control. It is possible to print 10 inches / s or 250 mm / s if external thermal history control is used. 2) 150km life realized for GL50 by attributing durable new protection film. 3) New partial glaze construction makes it compatible with the thermal transfer application. 4) Market-proven G-series printhead construction ensures high reliability. zExternal dimensions (Units : mm) 6.1±0.4 (5) 65 (4.5) φ20 (3) Max.45 Max.36 DOT #448 56 (EFFECTIVE PRINT WIDTH) DOT #1 #2 #20 #4 #1 Max.10 Max.5.5 28±0.3 56±0.3 φ3H10 (EFFECTIVE DEPTH 3) 17.8±0.2 7.3±0.3 15.3±0.3 (20.8) 25±0.5 #19 #1 CONNECTOR A CONNECTOR B 3-M3 (EFFECTIVE DEPTH 3) φ3H10 LENGTH 4 DOT #448 0±0.2 (EFFECTIVE DEPTH 3) 55.5±0.3 55±0.3 KF2002-GL50A Printheads zEquivalent circuit DOT #448 VH DOT #1 P−GND L−GND 7 6 5 4 3 2 1 VDD 64 OUTPUT EACH STB2 STB1 LAT LATCH REGISTER CLK SHIFT REGISTER DI2 DO2 DI1 DO1 TM THERMISTOR 30kΩ B: 3950 TM CONNECTOR DI No. DOT No. STB No. DOT No. DI1 1∼ 192 STB1 1∼ 192 DI2 193∼ 448 STB2 193∼ 448 Fig. 1 zPin assignments CONNECTOR A CONNECTOR B No. Circuit No. Circuit No. Circuit 1 L-GND 11 TM 1 VH 2 VDD 12 TM 2 VH 3 L-GND 13 DI1 3 P-GND 4 VDD 14 DO1 4 P-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.
