Direct shaft coupling

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.

Functional safety

Rotary encoders from this series are available with functional safety and a safe mechanical connection. Once integrated into an application with up to SIL 2 safety, they minimize malfunctions and facilitate the safe operation of machines and systems.

Flexible coupling

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

Compact design

The ECN/EQN 1100 series encoders feature high reliability and ruggedness in a compact design. Their small footprint makes them ideal for tight installation spaces.
