Product Description:
The RKL4487 cable is part of the RKL Motor Power Cables series produced by Bosch Rexroth Indramat. It is a motor power lead intended to link a drive controller to a size 2 terminal box motor within automated machinery, carrying both power and low-level control signals in one shielded assembly. By providing a dedicated connection between the controller and motor, the cable supports coordinated motion tasks where flexible routing through moving machine elements is required. The combined power and control bundle reduces the number of separate cable runs that must pass through moving machine sections.
The mechanical life of the cable is specified for 5,000,000 bending cycles, indicating suitability for frequent reciprocating motion along linear axes. It tolerates combined flex and twist up to ±180°/30 cm, so it can follow swiveling energy-chain paths without conductor fatigue. During motion, the jacket must not be forced below a dynamic bend radius of 7.5 × D; once installed and stationary, the minimum static radius is 5 × D. These limits help prevent insulation cracking and impedance drift. The cable is qualified for drag-chain installation and uses a direct connection layout to minimize additional in-cabinet junctions, while the motor end is prepared for terminal-box entry that keeps strain away from internal motor terminals.
Power is delivered through 3 + PE conductors with a copper cross-section of 6.0 mm², allowing continuous transmission of three-phase supply currents at up to 300 V. Auxiliary circuits use two 1.0 mm² and two 1.5 mm² control cores for temperature or brake signals. The separate auxiliary cores let the assembly carry secondary motor functions without requiring an additional cable at the same routing point. The bulk cable type is INK0604, and the controller-side molded plug follows the RLS0721/K06 coding for keyed mating to Rexroth power modules.
