Product Description:

The RKL0008 cable belongs to the RKL Motor Power Cables series manufactured by Bosch Rexroth Indramat. It is specified for routing three-phase power and auxiliary conductors between IndraDrive controllers and synchronous servo motors, allowing compact machine tools and handling modules to connect quickly without field-fabricated leads. By combining power and signal pairs in a single jacket, the assembly simplifies wiring tasks inside automation cabinets and dynamic cable tracks.

This model carries phase conductors with a cross-section of 1.5 mm² for the main motor current and an auxiliary pair sized at 0.75 mm² for temperature or brake supply circuits. Copper strands exhibit a loop resistance of 13.3 Ω/km at 20 °C, so voltage drop can be calculated precisely over long runs. For moving-axis installations, the dynamic bending radius is limited to 7.5 x D, maintaining conductor integrity during continuous flexing. The construction also withstands carriage accelerations up to 10 m/s², ensuring the insulation does not fatigue when rapid indexing cycles are demanded by the motion profile.

The outer sheath is coloured RAL 2003 (orange) and moulded from abrasion-resistant PUR, giving both clear visibility and oil immunity inside machining cells. When laid in a static harness the minimum loop is reduced to 5 x D, facilitating tight routing behind cabinet doors. Controller termination uses the keyed circular connector RLS0721/K02 while the motor end is supplied with pre-crimped ferrules, eliminating field tinning and ensuring uniform clamp pressure under vibration. Together, these attributes support reliable energy transfer, EMC compliance and quick replacement in preventative maintenance schedules.

Ordering through Wake Industrial is streamlined: same-day shipping is available for urgent requirements, each cable is covered by a 1-year warranty, and written quotations remain valid for 30 days to aid budget approvals.
