Product Information

IA6008-FE10A Contact image sensor heads Color image sensor heads for High-Speed Scanner IA6008-FE10A Contact Image Sensor Head with 3 times higher scanning speed due to 3ch outputs. Newly developed resolution change-over IC is employed which has improved noise resistance. Applications High speed reading equipment (i.e. document scanners, plotters, laser multifunction devices). Features 1) High speed reading capability due to 3 analog output. 2) Signal amplifier is built into the image sensor IC in order to increase immunity to external noise. 3) ROHM’s newly developed sensor IC reduces failures due to ESD (based on the IEC61000-4-2 standard). 4) With the proprietary prism, the output signal is maintained uniformly. 5) The ceramic substrate is used for excellent dimensional accuracy and thermal stability.
