Couplings
Bellows couplings provide cost-effective connection of the motor
and encoder. They are also able to correct any angular errors
between the drive and encoder.
These bellows couplings (FS) are used for safe connection of
applications and Sendix SIL encoders.
The safety-oriented bellows coupling has, in addition to the
metallic bellows, internal claws that ensure the driving of the
encoder in case of breakage of the bellows connection.
Example: d1 = 10 mm and d2 = 12 mm
