KD2008-CG50A is a thermal printhead manufactured by ROHM. It is suitable for devices that require thermal printheads capable of higher printing speeds, such as high-speed POS and label printer applications. KD2008-CG50A uses a special compact partial glaze and new heating element structure to achieve high-speed printing at 125 mm/s. The KD2008-CG50A is ideal for label printers that require high printing speeds.
The KD2008-CG50A is a compact medium‑speed thick‑film thermal printhead designed for high‑speed POS and label printer applications. It offers a printing width of 216 mm, 1728 dots, and can print at speeds up to 125 mm/s, with features such as a durable conductive protective film and reinforced power circuitry.
The datasheet lists electrical characteristics, pin configuration, timing diagrams, and recommended connector dimensions. It also includes curves for adaptive speed, density, energy, and thermistor behavior, together with usage notes and safety warnings.
