IA2004-CE40A Contact image sensor heads Image sensor heads for narrow-width scanners IA2004-CE40A The IA 04-ME/CE series sensors, compatible with A6 size media, feature a dual-arch structure, allowing straight pass reading (both-directions). In addition, they are compact, measuring only 119.5mm in length. zApplications Check readers, card scanners, and a variety of other image input devices. zFeatures 1) Signal amplifier integrated into each sensor IC in order to eliminate external noise ; compatible with 3.3V interface. 2) LED light source mounted on the same substrate as the sensor chip itself, resulting in a more compact, lightweight package. 3) Proprietary prism maintains a uniform output signal. 4) Ceramic substrate used, ensuring excellent dimensional and thermal stability. zDimensions (Unit : mm) CL No.1 Pixel 25±1 Max. 1.5 A 15.5±1 (NOTE 1) Deflection at the top of glass:0-0.25 Projection to platen is positive.
