The high-accuracy RI76 hollow shaft incremental encoder has been specially designed for large shaft diameters up to 42 mm. The housing diameter is only 76 mm, which makes this encoder ideal for use in motors, lifts and printing machines.

Shaft Connection

N/A Shaft fixing is done through a clamping ring either on the flange or cap side. As a rule, flange side clamping is better for smaller motors as the available shaft stub is correspondingly shorter.

On the other hand, cap side clamping is easier when there is sufficient shaft length available

Mounting Necessities

N/A In order to compensate for axial and radial shaft eccentricity as well as any angle offset, the encoder flange must not be rigidly mounted. Please mount the flange with a flexible stator coupling (e.g. hub shaft with tether) as torque support.

There are two flexible mounting plates:

  • A flexible hub shaft with tether (A) for higher levels of play and lower requirements for accuracy.
  • A rigid hub shaft with tether (N) for reduced play and rigid connection with Reduced swing angle. This is suitable in the case of higher accuracy and dynamics requirements.

Applications

N/A Motors, printing machines, lifts
