GP1A037RDK/GP1A037REK GP1A037RDK/ GP1A037REK OPIC Photointerrupter with Encoder Function ■ Features ■ Outline Dimensions 1. Linear encoder for reading linear scale 2. Since the multi-divided photodiode system is adopted, highprecision reading is possible even if the angle is deviated between the scale and encoder. 3.
