Hight Speed Thermal Printhead
(8dots / mm)
SE2002-DC90A
High speed, high quality, and high durability are achieved by using step free structure with high performance partial glaze
and highly conductive overcoat layer. SE200*-DC90A series are lined up which can accommodate with all types of
barcode labeling printers from Direct to Thermal Transfer, normal to high speed (over 300mm/s).
zApplications
Bar code label printers
Ticket printers
General purpose compact printers
zFeatures
1) ROHM new technology “STEP FREE” structure will provide, high corrosion resistance, better resistance against
scratching damage, high efficiency.
2) Standard glazed components to accommodate thick paper.
3) High speed clock (10MHz) to facilitate external heat history control.
4) Using a hard conductive film as a protective film on the heating element offers excellent resistance to electrostatic
damage.
5) Compatible with the SE3002-DC90A (300dpi) in mechanical specifications, to facilitate the making of a series of
printers.
