Product Description:
The RKL4474 power cable is produced by Bosch Rexroth Indramat within the RKL Motor Power Cables series. The assembly provides the fixed and mobile link between Rexroth servo drives and synchronous motors, carrying three-phase supply and auxiliary control cores in one sheath. It is intended for industrial automation routes where reliable power transmission, integrated sensor conductors, and compatibility with drag-chain routing are required.
RKL4474 is manufactured from bulk cable type INK0605; this core architecture defines conductor stranding, insulation thickness, and overall electrical rating. The main power trio employs a cross-section of 10.0 mm², enabling low voltage drop over long motor leads. Two control pairs sized 2x1.0 + 2x1.5 mm² are embedded for brake release and temperature sensor circuits, avoiding a separate feedback harness. A highly visible jacket in RAL 2003 (Orange) improves traceability in dense cable trays, while its PUR compound delivers resistance to oil and abrasion. Conductor insulation is rated for a maximum wire temperature of +80 °C, allowing continuous service near warm drive enclosures without thermal degradation.
Mechanical handling features complete the cable’s profile. The nominal outer diameter of 22.2 ± 1.0 mm fits standard Rexroth EMC glands and supports bending under static installation to a minimum of 5 x D, while dynamic drag-chain loops may flex to 7.5 x D without exceeding copper strain limits. Termination at the motor end uses the keyed power connector type INS0486, ensuring shield continuity and strain relief in one operation. The cable is approved for drag-chain use, with performance tested from −30 to +40 °C when fixed and −20 to +40 °C during continuous motion. The PUR jacket preserves flexibility under lubricants, delivering predictable service life in multi-axis gantry systems.
