Resistant to Bending of Robot Cables
Use Robot Cable that can withstand at least 20 million bends to the minimum bending radius (R)
given below or larger.
Note 1. The service life data for resistant to bending is based on test data. Use it for reference only,
and provide sufficient allowance.
Note 2. This value is the number of bends when electricity is conducted through the conductors that
will not result in cracking or damage to an extent that would affect the functionality of the
sheath. Broken shield strands may occur.
Note 3. If a bending radius smaller than the minimum bending radius is used, it may result in
mechanical damage or ground fault damage due to insulation breakdown. If it is necessary
to use a bending radius smaller than the minimum bending radius, consult with your
OMRON representative.
