Precise positioning

Rotary encoders with a bearing and stator coupling ensure consistently high accuracy. Thanks to optimally matched components, system accuracies of down to ±20 arc seconds are attained.

Direct shaft coupling

The encoder's hollow shaft allows it to 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.

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 ±1.5 mm can be reliably compensated for. The stator coupling also facilitates easy mounting to the plane surface.

Proven standard

The rotary encoders of this series boast high reliability and perfected technology in a robust design. For decades, they have proven themselves around the world in great numbers within elevators, printing machines, and machine tools.
