GP2D03
Paper Size Sensor System
■ Features
1. Paper size sensor system
• 2-beam paper size sensor GP2D03 3pcs.
2
PROM for data storage 1pc.
•E

2. High sensitive detection because of less
influence on the color or reflectivity of refl ective object thanks to position sensitive
detector (PSD
3. 2-beam type
