Product Description:
The RKB0013 is an industrial control cable produced by Bosch Rexroth Indramat and supplied within the RKB Control Cables series. Designed as an Ethernet link inside automated cells, it provides a factory-terminated line between servo drives, controllers, and decentralized I/O that communicate over the Sercos real-time protocol. By delivering predefined electrical and mechanical characteristics, the cable eliminates on-site assembly and supports deterministic motion control where timing, resistance to flexing, and reliable noise immunity are critical.
The bus interface is Sercos III, so the conductor geometry and shielding are tuned for full-duplex telegrams at 100 Mbit/s in ring or line topologies. Data integrity is further guaranteed by its Cat 5e rating, which specifies impedance, NEXT, and insertion loss for Gigabit Ethernet but offers ample margin for the Sercos signal. Continuous motion applications are addressed through a dynamic bending radius of 7.5 x D, while stationary installation only requires 5 x D, reducing cabinet space. Ambient service is allowed from -30 to 80 °C, enabling operation in chilled warehouses or heated enclosures. An 8-pin assignment matches standard Ethernet pair mapping without modification.
Mechanical longevity is defined by a flex life of 5,000,000 cycles, allowing repeated chain motions on gantries or pick-and-place axes. Because the assembly is Ready-Made, both ends arrive crimped and strain-relieved with shielded RJ45 plugs, and the straight housings simplify routing through cable trays. The basic construction variant keeps outer diameter and cost moderate while retaining the twisted-pair layout demanded by differential signalling. During shutdown the cable can be stored between -30 and 40 °C, and its straight connector orientation avoids torsional loading at the equipment ports.
