Product Description:

The RKL4402 motor lead is a factory-terminated cable manufactured by Bosch Rexroth Indramat within the RKL Motor Power Cables series. It is supplied as an accessory that links drive amplifiers to motors in automated machinery, carrying phase power and protective earth without additional field fabrication. In assembly lines, packaging equipment, or gantry axes, its preassembled conductors shorten installation time and provide connections that conform to the drive manufacturer’s electrical parameters. Factory termination also eliminates the need to prepare individual conductors during installation, reducing the number of cable assembly steps required at the machine.

The cable is rated for 5,000,000 flex cycles in continuous drag-chain service, so repeated motion does not prematurely fatigue the copper or insulation. A dynamic bending radius of 7.5 × D applies while the cable is moving, whereas a static bending radius of 5 × D applies to fixed routing inside control cabinets. These limits preserve conductor geometry and help prevent insulation damage at tight turns. The cable retains its electrical and mechanical integrity across a temperature range of -30 to 80 °C, allowing use in refrigerated zones or warm production areas. Because the assembly is delivered as a ready-made harness, no crimping or overmolding is required at the installation site.

The RKL4402 follows a basic construction guideline, using standard PVC insulation and shielding suited to typical industrial environments. It is designated as a power cable, so it carries motor phases and protective earth, while feedback channels use separate encoder leads. One end combines ferrules and a ring terminal for secure attachment to the appropriate terminals. The opposite end uses plain ferrules for integration with compatible spring-clamp or screw-clamp inserts. This termination arrangement provides prepared conductor ends for both connection styles without requiring additional stripping or contact installation in the field.
