SH2002-DC90A Datasheet | ROHM

.. Printheads Near edge thermal printhead (8dots / mm) SH-DC90 series was developed with two key structures step-free and near edge for the packaging printer market which requires high speed continuous printing. It is suitable for printers in factory line where high speed 24 hours continuous printing is required. z Applications Bar code printers Card printers Ticket printers General purpose pact printers z Features 1) ROHM new technology “STEP FREE” structure will provide, high corrosion resistance, better resistance against scratching damage, high efficiency. 2) Inclined toward the printing surface to provide excellent printing quality even for cards and thick paper. 3) Prints directly on printing medium that cannot be bent. 4) Using a hard conductive film as a protective film on the heating element offers excellent resistance to electrostatic damage. 5) patible with the SH3002-DC90A (300dpi) in mechanical specifications, to facilitate the making of a series of printers. z External dimensions (Unit : mm) DOT #448 (5) Max. 51 Max. 5 Pape r feed directi on 66±0.5 56 (EFFECTIVE PRINT WIDTH) 6±0.5 DOT #1 Max. 12 #2 #20 #4 #1 #1 φ3H10 EFFECTIVE DEPTH 3 #19 JST B4PS-VH HIROSE HIF3FC-20PA-2.54DS φ3H10 LENGTH 4 EFFECTIVE DEPTH 3 20.555±0.2 7.3±0.3 8±0.3 (13) 20±0.3 40±0.3 DOT #1 M3 EFFECTIVE DEPTH 3 Note: No heat history control function inside the thermal printhead.
