An ERN 1000 bearing rotary encoder with a cylindrical metal housing, blind hollow shaft, and stator coupling.

Direct shaft coupling

The encoder's hollow shaft allows it be directly coupled to the mating shaft. No additional rotor coupling is required. The high rigidity permits higher control-loop bandwidths while significantly reducing inaccuracy and installation complexity.

Precise positioning

Rotary encoders with a bearing and stator coupling ensure consistently high accuracy. Thanks to optimally matched components, system accuracies of down to ±18 arc seconds are attained.

Flexible coupling

The stator coupling compensates for play between the motor and the rotary encoder, thereby correcting inaccuracy. Even tilt and axial play of up to ±0.5 mm can be reliably compensated for. The stator coupling also facilitates easy mounting to the plane surface.

Compact design

The rotary encoders of this series feature high ruggedness and reliability in a compact design with an outer diameter of just 35 mm. Their small footprint makes them ideal for very tight installation spaces.
