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 ( Unit : mm ) GP2D03 (1pc. ) 2-4 30 1 Detecting portion 17.5˚ 32.3 32.5 21 (10.4) Emitting portion 4.25 4 5 17.5˚ 1.4 (3.2) 21 19 Connector terminal 1 VO 2 GND 3 V IN 4 V CC 5 LED ■ Applications 1.
