Printheads
Compact medium speed thick film thermal
printhead (8dots / mm)
KD2002-CG10A
KD2002-CG10A is suitable for devices, such as high-speed POS and label print er applications, that require thermal
printheads capable of higher prin ting rates. Improved power circui t design means that w ith heavier curre nt it is possible to
print at speeds as high as 150 mm/s. The GK Series is the thus ideal for label printers that need high printing rates.
zApplications
POS terminals, Label printers, CAT terminals, Multi-purpose small-si zed printers
zFeatures
1) Using a special compact partial glaze and new heating element structure, achieves high-speed printing at 150 mm/s.
2) The use of th e newly developed highly-durable co nductive protective film has improved co untermeasures 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 sma ll connectors, designed to conform with FFCs, and miniature driver chips have b een used. Although the
resulting printheads are sur prisingly com pact and lightweig ht, they can be use d with large p latens of up to 2 0 mm in
diameter.
5) One rank resistance value of 800Ω ± 3% eliminates the inconvenience of rank selection.
6) The required driving voltage of 3.15 to 5.25V allows wide range of power supply voltage setting. This also allows
multiple choice of electronic co mponents fo r printers.
7) 2-inch, 3-inch and 4-inch series are available.
