KD2004-CF20A

Printheads ax .2 2. 6± 0.

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 printing rates. Improved power circuit design means that with heavier current 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. Applications

ax .φ

POS terminals, Label printers, CAT terminals, Multi-purpose small-sized printers .0

Features 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 components for printers.
