Thick film thermal printhead (8 dots / mm)
KF2002-GL50A
The KF2002-GL50A is a 24 V standard thick film thermal printhead with a printing speed up to 6 inches / s that has been developed mainly for label printer use.
zApplications High speed label printer High speed bar code printer High speed ticket printer Various high speed terminal printers
zFeatures 1) Newly developed thick-film fast response thermal element is employed for this series and 6 inches / s or 150 mm / s is possible without thermal history control. It is possible to print 10 inches / s or 250 mm / s if external thermal history control is used. 2) 150km life realized for GL50 by attributing durable new protection film. 3) New partial glaze construction makes it compatible with the thermal transfer application. 4) Market-proven G-series printhead construction ensures high reliability.
