Product Description:
The RKB0023 cable is a communication accessory manufactured by Bosch Rexroth Indramat for the RKB Control Cables series. It provides a direct USB link between a computer or PLC interface and compatible Rexroth drives or controllers in industrial automation cells. Its shielded conductors provide a stable electrical path for parameter transfers and live diagnostics without requiring additional fieldbus hardware. The direct connection also simplifies access to drive data when a permanent network interface is unavailable.
The cable is supplied as a ready-made assembly, so the factory-terminated cord set reduces the risk of on-site pinout and wiring errors. Classified as a USB connection cable, it supports full-speed data exchange between host and target devices through the Universal Serial Bus interface. One end carries a USB-A plug that connects to a standard computer port. The controller end has a USB-B plug commonly used on drive and controller front panels. Mechanical endurance reaches 5,000,000 flex cycles, making the cable suitable for repeated movement in applications such as cable tracks on gantry axes. This level of flexibility helps protect the internal conductors from fatigue during recurring machine travel.
For installations with reciprocating travel, the recommended dynamic loop radius is 7.5 × D, which keeps strain on the outer jacket within acceptable limits. Fixed routing inside cabinets permits a tighter bend radius of 5 × D without compromising insulation integrity or signal quality. The conductors remain flexible at temperatures as low as -30 °C, allowing operation in refrigerated plants and other cold industrial areas. The insulation materials withstand sustained temperatures up to 80 °C, supporting installation in heated enclosures or near power electronics. These temperature and routing capabilities allow the cable to be installed in stationary controller cabinets or on moving machine axes.
