RKB0011 by Bosch Rexroth Indramat

The RKB0011 Ethernet patch assembly is produced by Bosch Rexroth Indramat within the RKB Control Cables series. The cable is delivered as a complete in-line harness that supports a dedicated drive-to-controller Ethernet link inside distributed servo cabinets. By combining factory-terminated plugs with a flexible industrial jacket, the product streamlines installation in machines that rely on synchronous communication between Rexroth drives and PLCs. Its preassembled format also avoids field termination work and helps preserve consistent pair integrity from one device port to the other.

The cable is classified by Rexroth as a Multi-Ethernet Cable, which indicates electrical characteristics suitable for multiple real-time industrial protocols rather than a single fieldbus. Each end uses RJ-45 (RBS0016) connectors on both ends that lock into standard ports through an internal snap-in retention clip, helping prevent vibration-related disconnection. For signal throughput, it supports a 100 Mbit/s data rate that corresponds to the 100BASE-TX (IEEE 802.3u) interface layer. An Overall Shielded (EMC) braid and foil package surrounds the twisted pairs, reducing common-mode noise so timing remains stable on electrically noisy factory floors.

Assembly code RBS0016-REB0400-RBS0016 shows that the bulk conductor at the core is type REB0400 and that both molded connectors are fitted to the finished cable. The REB0400 inner build carries a conductor system rated for 600 V, allowing the cable to share mixed-voltage wireways while maintaining suitable electrical separation. A PUR (polyurethane) outer jacket resists oil, coolant, and continuous motion in cable chains while remaining flexible at low temperatures. Pair mapping is aligned with SERCOS III / EtherCAT / PROFINET / EtherNet/IP pinouts, so the cable can be used with different compatible control networks without changing the physical connector format.
