ROHM SH3002-DC90A Technical data
Near edge type thermal printhead(11.81dots / mm)
SH3002-DC90A
SH-DC90 series achieves high quality print and high reliability, by Rohm unique Step Free Technology.
SH-DC90 series is near edge type thermal head, whose heater line is formed at the angle of the glaze. Therefore, peeling-off
ribbon at the hot state and large size platen can be used with this thermal head and is best suitable for the packaging printer
market which requires the continuous print at high speed.
zApplications
Barcode label printers
Packaging printers
Ticket printers
General purpose portable printers
zFeatures
1) ROHM unique “STEP FREE” structure contributes to better anti-corrosion characteristics, less scratch break down, and
better heat efficiency.
2) Thermal head contacts with the media by angle at the print, so that good print quality can be obtained for the thick media.
3) It has good anti-ESD characteristic by applying hard, conductive layer as the heat element protective coating.
4) Mounting space can be minimized, which contributes to the downsizing of the printer.
