Near edge thermal printhead (with thermal historical control)
SH3002-DC80A
SH3002-DC80A achieves high quality print and high reliability, by Rohm unique Step Free Technology. SH3002-DC80A is near edge type thermal head, whose heater line is formed at the angle of the glaze. Therefore, it is applicable to large diameter of platen and heat-peeling ribbon. Especially it is suitable to the packaging market that requires ultra high speed printing over 1,300mm / s. Applications Barcode label printers Packaging printers Ticket printers General purpose portable printers Features 1) ROHM unique "STEP FREE" structure contributes to better anti-corrosion characteristics, less scratch break down, and better heat efficiency. 2) Against the printing surface, the print head should be used at a slant during a print due to its structure, therefore, it is applicable to heat-peeling ribbon in high speed. 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. 5) It has built-in history control and pre-heat function. It is possible to print at over 1,300mm / s. Dimensions (Unit : mm)
