Printheads
For Mobile, FET-POS, Debit Card, PDA, ECR
2.7V Print Voltage (B Series)
KA2004-BE51A
Not only hand-held printers, but card payment terminals (EFT-POS) and compact label printers require less than 8.5V of
supply voltage.
ROHM’s B Series of thermal printheads, developed using cutting-edge LSI technology, can operate on a single lithium
ion battery and contribute to end-product miniaturization.
zApplications
Mobile printers
EFT-POS printers
Hand-held printers
Debit printers
zFeatures
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 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.
