KD2004-CF20A
Printheads
Compact medium speed thick film thermal
printhead (8dots / mm)
KD2004-CF20A
KD2004-CF20A is suitable for devices, such as high-speed POS and label printer 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 terminal s, 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 the 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) One rank resistance value of 800Ω ± 3% eliminates the inconvenience of rank selection.
5) 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.
