What is the difference between EE-1010 and EE-1010-R Connectors with Cables?

EE-1010 uses a regular cable, but EE-1010-R uses a robot cable, which provides superior flexibility. (The robot cable can be bent more than approximately three times as many times as the regular cable. Use a bending radius of at least three times the diameter of the cable.)

Using EE-1010-R is recommended if the cable is to be connected to a moving part.
