LSH2001-AA10A_11

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) Dimensions (Unit : mm) 40±0.5 35 29 (Reading Width) 16.25 3 +0 2.5 .1 0 0 .1 -0 Max.15 12.68 (Focus Point) 11.68 (Surface Level) 2− φ Scanning Line Paper Feed Direction .5 φ1 2− (2.5) No.130 Pixel No.1 Pixel 3.25 8 8.18 (Focus Point) 7.18 (Surface Level) 4−C0.5 Pin No. Signal Pin No. Signal No.11 No.1 No.1 No.2 No.3 No.4 No.5 No.6 GND Ao GND GND G-LED V-LED No.7 No.8 No.9 No.10 No.11 CLK SI GND GND VDD 4− R1 (NOTE 1) Deflection at the top of glass : ±0.5 (NOTE 2) It is possible to design ±0.2 tolerance. 1.5 9.2±0.5 13.45 2−φ 0 -0. 1 (Connector No.) Housing : SHR-11V-S-B Base : SM11B-SRSS-G-TB 14 6 www.rohm.com c ○ 2011 ROHM Co., Ltd.
