Product Description:
The RKL4742 motor power cable is produced by Bosch Rexroth Indramat within the RKL Motor Power Cables series. It serves as the three-phase energy conduit between drive controllers and motors in automated cells, transferring both power and control potentials. The cable’s PUR jacket, finely stranded copper cores, and EMC-aware geometry allow installation in machine tools, packaging lines, and gantry axes where oil resistance, abrasion tolerance, and repeat flexing are routine.
Electrically, the cable has an outer diameter of 29.8 mm, enclosing four power conductors each with a cross-section of 25.0 mm² to limit voltage drop on runs up to the drive cabinet. The copper path exhibits a conductor resistance of only 0.78 ohm/km at 20 °C, enabling stable current delivery under high acceleration loads. Nominal insulation supports a power operating voltage of 300/500 V, while an auxiliary pair inside the sheath carries 300/300 V control signals for brake release or thermal sensors.
For mechanical reliability, the cable may be laid in static trays with a minimum bend of 5×D, yet it also tolerates dynamic cable-chain travel down to 7.5×D without core fatigue. The outer sheath withstands continuous conductor temperatures up to +90 °C when fixed, or +80 °C during motion. Overall mass is limited to 1.750 kg/m, reducing drag on moving axes while maintaining crush resistance and chemical stability.
Wake Industrial stocks this cable for immediate order fulfillment, and same-day shipping is available on requests processed before the daily cutoff. Quotations issued for the RKL4742 remain valid for 30 days to aid budgeting. Maintenance teams can secure replacement leads quickly thanks to consistent inventory.
