What it is, what it fits
The R88ACRKC010NRE: This is a 10-meter encoder cable for Omron G5 servo motors. It's the exact cable you'd pull off the shelf to replace a damaged one on a machine or to wire up a new axis. Length is the only variable — same connector, same pinout, same jacket. If the cable run needs to be longer or shorter, the sibling cables in the R88ACRKC line (3m, 15m, 20m) are the same otherwise.
