Product Description:
The RKL4468 cable is produced by Bosch Rexroth Indramat within the RKL Motor Power Cables series. It is a hybrid motor lead that carries drive power and auxiliary control circuits between IndraDrive servo amplifiers and matching motor terminal boxes. In industrial automation this type of pre-assembled cable simplifies field wiring, maintains impedance consistency, and preserves EMC compliance for synchronous servo axes that demand predictable power distribution.
Four copper cores with a collective cross-section of 4x10.0 mm² deliver the phase current; the dimension is a trade-off between ampacity and overall flexibility. This geometry offers low conductor resistance for mid-range servo duties. A braided-foil Total Shield encloses the assembly and is bonded to the controller through the INS0486 power connector. Two shielded pairs of 1.5 mm² control wires carry sensor and brake signals, and the set matches terminal box size 2 on the motor. Mechanical bulk is limited by an outer diameter of 22.2 mm, while the halogen-free PUR jacket resists cutting oils and abrasion. Copper conductors may operate continuously up to 80 °C without derating.
For routing inside drag chains the RKL4468 is specified for alternate bending use, meaning it endures repeated reverse cycles without conductor fatigue. Minimum static installation curvature is 111.0 mm, and when the cable moves the permissible radius increases to 166.5 mm to preserve insulation integrity. The INK0605 gland locks the jacket to panels using a metric thread of M32 × 1.5. An Orange (RAL 2003) outer jacket improves visibility in crowded cable trays and differentiates power feeds from signal lines.
