OPIC Photointerrupter with
Encoder Function
1. Linear encoder for reading linear scale
2. Since the multi-divided photodiode system is adopted, high-
precision reading is possible even if the angle is deviated
between the scale and encoder.
3. High resolution:
Resolution 150LPI (GP1A038RBK/GP1A038RBKL)
Resolution 180LPI (GP1A038RCK/GP1A038RCKL)
