RKB0063 by Bosch Rexroth Indramat

The RKB0063 flexible video-control cable is produced by Bosch Rexroth Indramat. It is intended for drag-chain installations where motion controllers, drives, and operator displays must exchange high-resolution video signals without intermittent faults. Matched impedance conductors support stable transmission during repeated movement, while the abrasion-resistant jacket helps protect the cable in automated assembly cells, packaging lines, and robotic enclosures. Its flexible construction suits applications where routing changes constantly with axis travel. Because it carries video rather than motor power, the cable is suited to links where display quality and low signal interruption are important during machine motion.

The cable is rated for 5,000,000 bending cycles, indicating its expected endurance under repeated motion. During dynamic use, it must be routed with a minimum bend radius of 7.5 × D, while fixed installation permits a tighter radius of 5 × D. The controller side uses a DisplayPort plug, and the device end uses the same connector style, so the termination format stays consistent across the link. It belongs to the RKB Control Cables series and is intended for applications that require reliable signal transfer in moving cable carriers. Following these bend limits helps reduce conductor fatigue and preserves the shielding geometry needed for stable video transmission.

During operation, the cable remains flexible from -30 °C to 80 °C, allowing use near chilled process areas or warm electrical equipment. For storage, the temperature should not exceed 40 °C so the jacket material is not exposed to unnecessary thermal aging while the cable is not in service. These limits apply to the insulation and shielding system that protect video transmission from mechanical stress and temperature-related stiffening. This operating range supports installations where the cable passes between cooler product zones and cabinets that dissipate heat during normal machine operation. Stable thermal performance also helps the cable maintain reliable movement in drag chains over long operating periods.
