SH2002-DC70A Datasheet | ROHM

.. Printheads Near edge thermal printhead (with thermal historical control) SH-DC70 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 printer Label printer Packaging printer ATM Ticket printer z Features 1) ROHM new technology “STEP FREE” structure will provide, high corrosion resistance, better resistance against scratching damage, high efficiency. 2) Head inclination by near-edge structure, applicable to the large-size platen. Resin type thermal-transfer ink-ribbon can be used. 3) High-hardness protect cote type “W-coat” is employed with 150km abrasion life-time. 4) A built in history-control functionality, high-speed printing up to 300mm / s can be achieved with clear print image. z External dimensions (Unit : mm) 8±0.3 66±0.5 (5) 56 (Effective print width) DOT No.1 6±0.5 40±0.3 20±0.3 (13) 34.0±0.5 MAX.58 Print Direc φ3 H10 Length 4 Effective Depth 3 MAX.5.5 MAX.12 7.3±0.3 φ3 H10 Effective Depth 3 M3 Effective Depth 3 #2 #20 #4 #1 CONNECTOR A #1 #19 CONNECTOR B TYPE OF PRINTHEAD 24.455±0.3 tion 1/3 ..
