Product Description:

The RKB0041 belongs to the RKB Control Cables series manufactured by Bosch Rexroth Indramat. It is a shielded control cable used to link drives, I/O modules, or operator panels over the proprietary Systembus within an automation cell. By providing a matched impedance path and preset connectors, the cable supports reliable data exchange between motion controllers and auxiliary components during machine movement. The shielding also helps reduce interference from nearby power wiring in compact control layouts. Its preassembled format supports quick connection between compatible devices inside the machine.

The conductor bundle is rated for 3,000,000 bending cycles, so the jacket can flex repeatedly in moving-axis assemblies before fatigue occurs. One end terminates in an M12 plug and the opposite end in an M12 socket, allowing tool-free coupling while preserving the line shielding. Communication is carried on the dedicated S-BUS interface, which keeps signal transmission consistent across compatible devices. Mechanical strain relief is designed for a 60 N tensile load, which is the greatest permissible pull during installation or movement without stretching the copper strands. The cable is not intended for drag-chain use, so routing should avoid continuous unsupported travel paths that exceed its static design.

When clamped, the assembly requires a ≥5×OD minimum bend radius, because tighter curves can compress the dielectric and affect impedance. Installation is permitted at ambient temperatures from 0 to +50 °C, and the cable can operate in conditions from -20 to +60 °C after it is mounted. For storage, the allowed temperature range is 0 to +50 °C, which helps protect the insulation and connector seals before use. Each lead is factory terminated at both ends, so it can be connected without additional crimping or soldering. This helps maintain consistent connection quality during installation.
