The hollow shaft allows the rotary encoder to be directly coupled to the mating shaft. An additional rotor coupling is not required. The resulting high rigidity permits higher bandwidths in the control loop, reduces inaccuracy, and simplifies installation.
The ERO 1400 rotary encoders include versions with built-in interpolation. With up to 25-fold interpolation of the output signals, very high resolutions can be attained for precise positioning.
The rotary encoders of the ERO 1400 series feature high reliability and ruggedness in a compact design. Their small footprint makes them ideal for very tight installation spaces.
