Ultra-small multi-line 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) Dimensions (Unit : mm) 40±0.5 35 Max.15 2.5 29 3 12.68 (Focus Point) .1 0 2.4 φ 11.68 (Surface Level) 0 .1 -0 .5 φ1 2− Paper Feed Direction 2− 9.2 +0 (Reading Width) 16.25 (2.5) 3.25 8 Scanning Line No.130 Pixel 8.18 (Focus Point) No.1 Pixel 7.18 (Surface Level) 4−C0.5 No.11 No.1 4− R1 0 -0. 1 14 www.rohm.com c 2009 ROHM Co., Ltd.
