| NE3002-GV10A Printheads Near edge thermal Printhead NE3002-GV10A A near-edge structure and Real Flat glazing technology make it possible to use the NE printhead for straight path printing. This thermal printhead is made for card and heavy stock paper applications. Because the thickness and quality of the print media matter little, the NE is suitable for a wide range of applications. !Applications Card printers Ticket printers !Features 1) The use of ROHM's proprietary G-form structure ensures a compact form and light weight. Naturally, it also means that the NE can be used without a heat sink. This gives engineers greater freedom when designing the printer mechanics. 2) Owing to the excellent smoothness of the surface of the print face, it is possible to achieve excellent print quality even when printing on hard card. 3) Inclined toward the printing surface to provide excellent printing quality even for cards and thick paper. !External dimensions (Units : mm) 650.5 (5.396) 54.208 (Effective Print Width) 50.5 550.2 50.2 Max.25.0 No.15 No.1 No.15 CONNECTOR B CONNECTOR A Prin t Dir ectio n No.1 (12.5) 5.10.1 Dot #640 Dot #1 1/4 NE3002-GV10A Printheads !Equivalent circuit VH GND 10 VDD 9 8 7 6 5 4 3 2 1 DOT #640 DOT #1 VH GND VDD / STB2 / STB1 LATCH REGISTER CLK DI4 SHIFT REGISTER DO4 SHIFT REGISTER / LAT DO1 DI1 DO3 DI3 DO2 DI2 TM THERMISTOR 30k B : 3950 TM CONNECTOR : B CONNECTOR : A DI, STB DIVISION DOT No. CORRESPONDENCE DI No. DI4 DI3 DI2 DI1 DOT No. 640~449 448~321 320~193 192~1 / STB No. / STB2 / STB1 DOT No. 640~321 320~1 Fig. 1 2/4 NE3002-GV10A Printheads !Pin configuration CONNECTOR A : IL-Z-15P-CLIP (JAE) PIN No. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 SIGNASL CONNECTOR B : IL-Z-15P-CLIP (JAE) PIN No. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 SIGNASL VH VH VH VDD / LAT DI1 DO1 GND GND GND GND DI2 DO2 / STB1 TM TM / STB2 DI3 DO3 GND GND GND GND DI4 DO4 CLK VDD VH VH VH !Characteristics Parameter Dot pitch Pulse width Pulse cycle Applied power Applied voltage Maximum clock frequency Maximum roller diameter Life Maximum number of dots energized simultaneously Operating temperature Effective printing width Total dot number Res. value of heat element Symbol - Ton SLT PO VH - - - - - - - Rave Typ. 0.0847 0.47 1.5 0.19 24.0 10 50 / 1x108 320 5~45 54.208 640 3000 Unit mm ms ms W / dot V MHz - km / pulses dots C mm dots 3/4 NE3002-GV10A Printheads !
