Printheads
Compact low voltage thick film
thermal printhead (8dots / mm)
KF2002-GF94A
KF2002-GF94A
KF2002-GF94A of low voltage thermal printheads have a 1.25-mm pitch connectors and reduced power supply circuit
voltage requirements. This makes them useful for a wide range of applications, including CAT, FET-POS and naturally,
handheld devices that demand printer heads which can operate with low supplied voltage.
!Applications
Mobile printers
FET-POS printers
Hand-held printers
Debit printers
!Features
1) Both the circuit voltage and the voltage required during printing are 3.3V ; this allows the design of complete printer
assemblies with energy-saving low power consumption.
2) KF2002-GF94A has a resistance value of 176Ω and can take a maximum current of 8.5V for printing. This is useful in
applications where the peak voltage is restricted.
3) Because the connectors accept 1.25-mm pitch FFC (full flat cables) it is possible to reduce the size of printer
mechanism control boards.
