LinkPhotoelectric Angle Encoder
Photoelectric angle encoder A90H is a high end incremental encoder that produces up to 1.800.000 output pulses per revolution. It has hollow shaft, integrated stator coupling and the accuracy of up to ±5 arc. sec. and is available in two different mounting types – coupling via shaft collar or via central screw.
