Thick Film Thermal Printhead (300dpi)
KD3002-DC92A
KD3002-DC92A is developing type of GL40 series which are developed mainly for label printe rs. We have adopted low coefficient of abrasion and conductive protection coat to GL40 series which are possible for high speed and good printing quality. That is KD3002-DC92A which is 24V standard thick film thermal print head with high speed, high quality of printing, high durability, long life, and strong resistance to abration.
Applications High speed label printer Food label printer High speed ticket printer High speed terminal printer
Features 1) Perform 150km life time adopting new protective coat. (Perform three times life time by coefficient of abrasion which is about is about 1/10 of current mass-producing coat.) 2) Build in thermal high speeded heater and perform high printing 4 IPS. (100mm / s) 3) Available for thermal transfer printing by adopting specific partial glaze..
