RKL4708 Bosch Rexroth Indramat

Product Description:

The RKL4708 cable is manufactured by Bosch Rexroth Indramat as part of the RKL Motor Power Cables series. Intended for dynamic servo axes, it carries motor power along with two pairs of control cores, linking a drive fitted with an RLK1201 motor connector to an RLS0722/K04 controller plug. The assembly maintains signal integrity and mechanical reliability in continuous-flex energy chains used throughout industrial automation.

Mechanical endurance is defined by a flex rating of 5,000,000 cycles, so carriage and gantry systems can move for years without conductor fatigue. When the cable is rigidly clamped, a minimum loop of 5xD is required, while on moving carriers the bend must not fall below 7.5xD; these limits prevent copper strand breakage and shield cracking. With an outside diameter of 17.0 mm, the assembly fits standard chain separators, and its outer sheath is made from PUR, giving abrasion resistance and coolant tolerance during machining operations.

Electrical capability matches medium-power servo demands. The three power cores each feature a cross-section of 4.0 mm², supporting balanced phase currents at up to 600 V AC without excessive heating. Two supplementary control pairs, sized at 1.0 mm² and 1.5 mm², accommodate temperature sensors or holding-brake feeds, and all conductors share a common ground screen to reduce interference. Continuous motion can be performed in environments where conductor temperature reaches 80 °C, ensuring reliable performance adjacent to motors or within warm control enclosures.

Wake Industrial offers a 1-year warranty on every RKL4708 cable. Same-day shipping is available for orders finalized before the daily dispatch cut-off. For wiring details or fault-code questions, the free chat tool provides quick, general guidance.
