KA2002-BE10A printheads rev.a 1/4 for mobile, fet-pos, debit card, pda, ecr 2.7v print voltage (b series) KA2002-BE10A 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. z applications mobile printers eft-pos printers hand-held printers debit printers z 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 tec hnology 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. z dimensions (unit : mm) (1.1) max.1.7 (7.35) exposed conductor side insert direction (10) max. 8.0 1.4 0.3 max.12.5 no.21 no.1 connector 54 48 (effective print width) dot #1 dot #384
