Add-on Structure Contact Image Sensor Heads LSH3008-CA50A The Basic CIS by which the add-on can shorten the development period of a product sharply while being able to satisfy broad demand. A taper glass and tempered glass can respond as an option. As a measure against a paper jam, the custom-made correspondence of the special cantact plate can be carried out. Applications Document Scanners,Bill sorters.Wide Format Scanners,and Lottery. Features 1) High speed reading capability due to 3 analog output. 2) Signal amplifier integrated into each sensor IC in order to eliminate external noise ; compatible with 3.3V interface. 3) LED light source mounted on the same substrate as the sensor chip itself, resulting in a more compact, lightweight package. 4) Proprietary prism maintains a uniform output signal.
