KF2004-GR40A

KF2004-GR40A Printheads Compact medium speed thick film thermal printhead (8dots / mm) KF2004-GR40A The KF2004-GR40A is ideal for applications that require compact, lightweight thermal printheads, such as POS and label printer applications. The 2-, 3-, and 4-inch sizes have a resolution of 203dpi. This series is suitable for a wide range of applications. !Applications POS printers Label printers Receipt printers General purpose compact printers !Features 1) Both ROHM’s advanced LSI technology and proprietary partial glaze are used to realize higher printing efficiency. With a high print speed of 100mm/s, this series is also suitable for thermal transfer printing. 2) Besides the fact that harness-type direct connectors at either end allow wring to be fitted as convenient, the thermal printheads can be applied directly to the substrate without a heat sink. Both these features give engineers greater freedom when designing the printer mechanism. 3) One rank resistance value of 800Ω ± 3% eliminates the inconvenience of rank selection. !External dimensions (Units : mm) 119 (HEATSINK WIDTH) DOT #864 16 15.1 Max. 1.7 5.85 DOT #1 Max . φ1 4.0 108 (EFFECTIVE PRINT WIDTH) 2.6 No.9 No.1 No.9 No.1 CONNECTOR B CONNECTOR A 5 4.6 109 2-M3 1/4 KF2004-GR40A Printheads !Equivalent circuit VH GND 8,9 1,2 DOT #864 DOT #1 1,2 8,9 VH GND 6 STB4 STB3 5 6 5 4 3 2 1 7 STB1 6 STB2 5 LATCH REGISTER DI V DD 7 SHIFT REGISTER 4 THERMISTOR 3 4 LAT DO CLK TM 3 CONNECTOR B CONNECTO...
