ROHM KD2008-CG50A Technical data
Compact medium speed thick film thermal printhead(8dots / mm)
KD2008-CG50A
KD2008-CG50A is suitable for devices,such as high-speed POS and label printer applications, that require thermal
printheads capable of higher printing rates. Improved power circuit design means that with heavier current it is possible
to print at speeds as high as 125 mm/s. The GK Series is the thus ideal for label printers that need high printing rates.
Applications
POS terminal printers
Label printers
CAT printers
General purpose compact printers
Features
1) Using a special compact partial glaze and new heating element structure, achieves high-speed printing at 125 mm/s.
2) The use of the newly developed highly-durable conductive protective film has improved countermeasures against
static electricity.
3) The VH and GND sections of the power circuitry have been strengthened so that heavier current can be applied.
4) Ultra small connectors, designed to conform with FFCs, and miniature driver chips have been used.
Although the resulting printheads are surprisingly compact and lightweight, they can be used with large platens of up
to 20 mm in diameter.
5) One rank resistance value of 8003% eliminates the inconvenience of rank selection.
