Product Description:
The RKL0057 belongs to the RKL Motor Power Cables series from Bosch Rexroth Indramat. It is a pre-assembled power lead that links IndraDrive controllers to compatible servo motors, carrying phase current, protective earth, and auxiliary signals while withstanding constant flexing in energy-chain installations.
This cable uses a power-core cross-section of 2.5 mm², providing ample conductor area for the motor’s continuous current without excessive voltage drop. Four signal conductors are integrated; the presence of 4 auxiliary cores allows temperature or brake channels to travel in the same sheath. For moving-axis layouts, the design supports a dynamic bend radius of 7.5xD, whereas routing in fixed trays may follow a tighter static radius of 5xD. Endurance is verified for 5,000,000 flex cycles, so repeated traverses in pick-and-place gantries do not compromise insulation or screening.
A jacket compound of PUR resists mineral oils and welding spatter, and its high-visibility hue is coded as RAL 2003 to match the Bosch Rexroth safety color scheme. Thermal ratings span from 80 °C down to -30 °C; the cable therefore remains pliable in refrigerated halls yet tolerates enclosure hot spots near drives. Factory-crimped connectors—INK0602 on the bulk reel, RLS0749/K03 at the controller end, and RLS1108/C03 at the motor—eliminate field terminations and keep shielding integrity intact.
Wake Industrial stocks this cable, can arrange same-day shipping for urgent orders, and backs every purchase with a 1-year warranty. A free chat tool is available for questions on connector pinouts, type codes, or compatible drive families.
