Ultra-small Contact Image Sensor Heads, covering
the character recognition
LSH2001-AA10A
Easy to mount on whatever sets because of its small size, this is the device best suitable for whatever detecting thanks to its
deep focus point and high recognition accuracy.
Applications
Detection sets (e.g. surface, paper edge, paper type)
Features
1) Its deep focus point enables scanning of the object without close contact to the glass bed of scanner, so that both the
scanned object and the scanner bed won’t be damaged.
2)Screw holes and the alignment pin are provided for convenience of mounting.
3)16.25mm read width (40mm total width)
