KA2002-BE10A
Printheads
Compact Battery drivable thick film thermal printhead (8dots / mm)
KA2002-BE10A
Compact and lightweight they are ideal print heads for handheld printers and PDAs (personal digital assistants).
Applications Mobile printers EFT-POS printers Hand-held printers Debit printers
Features 1) The B series brings reduced height of protective resin for IC and enlarged paper pathway for thermal papers. Thanks to ROHM's latest LSI high integrated mounting technology and it's ultra slim 192bit driver IC. 2) The B series accede the great world class low energy consumption characteristics of GP series. 3) Because the print heads circuits draw 2.7V, the printer can be driven using a single lithium battery.
