Product Description:

The RKL0018 motor power cable is produced by Bosch Rexroth Indramat as part of the RKL Motor Power Cables series. It forms the electrical link between IndraDrive controllers and synchronous servomotors, carrying three-phase power and protective earth while tolerating continuous motion in cable chains used throughout automated assembly and packaging machinery.

For dynamic motion applications, the cable permits a minimum loop of 7.5xD when the carrier is moving and 5xD when routed statically, allowing tight routing without exceeding copper strain limits. The PUR jacket and finely stranded conductors survive up to 5000000 flex cycles inside drag-chains, so replacement intervals in high-duty production cells remain long. Connection is simplified by the controller-side plug RLS0746/K03, matched on the motor end by the keyed power plug RLS1201/C04; both connectors are moulded to prevent ingress and maintain low contact resistance during vibration.

The permissible service envelope spans from -30 °C during start-up to ambient peaks of 80 °C, so the assembly can operate in chilled warehouses or warm press shops without thermal derating. Conductor geometry follows the INK family, and this specific sheath is designated INK0602, which identifies insulation thickness and flame class for machinery approval. Protective earth insulation is distinguished by the striped GNYE colouring, making visual continuity checks fast during maintenance rounds and avoiding wiring errors when multiple cables enter the same cabinet.

Wake Industrial stocks this cable for immediate replacement needs. Same-day shipping is available on qualifying orders, reducing conveyor downtime. Quotations issued for the RKL0018 remain valid for 30 days to support straightforward budgeting.
