GP2D03 - Sharp

GP2D03
GP2D03
Paper Size Sensor System
■ Features
■ Outline Dimensions
1. Paper size sensor system
• 2-beam paper size sensor GP2D03 3pcs.
• E 2PROM for data storage 1pc.
[Serial access type, memory capacity : 128 x 8 bit]
( E 2PROM shall be applied to users'. )
2. High sensitive detection because of less
influence on the color or reflectivity of reflective object thanks to position sensitive
detector ( PSD )
3. 2-beam type ( GP2D03 )
4. With initial mode in order to make E 2 PROM
store thresh level for the existence of
reflective object
