Printheads pact low voltage thick film thermal printhead (8dots / mm)
KF2003-GF84A 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 plete printer assemblies with energy-saving low power consumption. 2) KF2003-GF84A 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. 4) 2-inch, 3-inch and 4-inch series are available. !External dimensions (Units : mm)
