KD2004-CF20A is a compact medium-speed thick film thermal printhead (8dots/mm) 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.
The KD2004-CF20A is a compact, medium‑speed thick‑film thermal printhead designed for high‑speed POS terminals, label printers, CAT terminals, and other small‑sized printers. It offers a printing width of 108 mm and can operate at speeds up to 150 mm/s.
Key features include a durable conductive protective film, reinforced power circuitry for higher current, a fixed resistance of 800 Ω, and a driving voltage range of 3.15 V to 5.25 V. The manual details dimensions, equivalent circuit, pin assignments, timing charts, and electrical characteristics such as voltage, power, and temperature limits.
