| GP2D03 GP2D03 s Features 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 Paper Size Sensor System s Outline Dimensions GP2D03 (1pc. ) 21 (10.4) ( Unit : mm ) 30 Detecting portion 32.3 Emitting portion 4 17.5 R4.25 21 3.2 2-4 1 17.5 32.5 5 4.25 1.4 (3.2) 19 Connector terminal 1 VO 2 GND 3 V IN 4 V CC 5 LED s Applications 1.
