GP1A038RBK/GP1A038RBKL/GP1A038RCK/GP1A038RCKL
GP1A038RBK/GP1A038RBKL/ GP1A038RCK/GP1A038RCKL
I Features
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. High resolution: Resolution 150LPI (GP1A038RBK/GP1A038RBKL) Resolution 180LPI (GP1A038RCK/GP1A038RCKL)
