If the cable is used in a moving part, use a flexible cable.
The flexing life of a Flexible Cable is estimated under the following conditions.
Precautions for Correct Use
• Because the lifetime data on resistance to bending is intended for reference only, use the
cable with a sufficient margin.
• The minimum bending radius refers to the value at which the core conductor provides electri-
cal continuity without causing cracks and scratches that can have functional impact on the
sheath, which does not cover the disconnection of shielded wire.
• Malfunction or grounding fault due to dielectric breakdown may occur if cables are used at a
radius smaller than the minimum bending radius.
