The Omron R88ACAKA005SRE is a 5-meter power cable for G5 servo motors, rated 200V, without brake. It's the cable that runs between the servo drive and the motor on a G5 series axis.
The R88ACAKA010SRE is functionally identical in design (Suitable for G5 Servo Motors, Accessory Type: Power Cable) but supplied in a longer length. If your BOM calls for the longer version, the 5m cable fits the same connectors — the only trade is reach.
This cable does not include brake wiring; if your servo motor has a holding brake, order a brake-equipped cable variant. Fit is limited to Omron G5 motors.
