RKL4467 by Bosch Rexroth Indramat

The RKL4467 motor power cable is manufactured by Bosch Rexroth Indramat and belongs to the RKL Motor Power Cables series. It is engineered for industrial automation tasks where a single lead carries motor power and auxiliary control conductors between a drive and a moving servo axis. The cable is used in drag-chain assemblies and stationary runs, allowing machinery builders to maintain consistent electrical performance while accommodating the mechanical motion of linear stages, gantries, and articulated robots.

For static routing, the minimum permitted bend radius is 5 x D, and during continuous motion the minimum bend radius is 7.5 x D; both limits help protect the insulation from stress cracking. The multicore layout of 4x6.0 mm² + (2x1.0)StC + (2x1.5)StC groups four power conductors with two shielded control pairs, keeping motor and sensor circuits in one jacket. Copper resistance is rated at 3.30 ?/km at 20 °C, a value that affects voltage drop over long machine sections. The mutual capacitance of 0.8 nF/m limits reactive current and helps the drive meet EMC targets. The cable is approved for drag-chain use, and its halogen-free compound reduces corrosive gas release during a fire event.

Thermal limits differ by installation: fixed wiring can reach 90 °C, whereas flexing segments must remain below 80 °C. A PUR jacket with an adhesion-free matte finish resists oils and weld spatter while simplifying bundle separation, and the overall diameter is 18.5 mm, which fits common energy-chain separators. The power cores and the internal control pairs share a voltage class up to 600 V AC, so separate trunking is unnecessary in mixed-signal cabinets. Rated control voltage is identical, which keeps insulation coordination uniform across the entire length.
