Product Description:

The RKB0016 is a pre-assembled communication cable manufactured by Bosch Rexroth Indramat within the RKB Control Cables series. This cable links Indramat drives, controllers, and decentralized I/O to a CAN-based system bus, transferring differential signals with low latency and requiring minimal installation work. Its mechanical construction is intended for continuous flexing inside energy chains, allowing automated axes to remain synchronized while the cable moves with the carrier. It also supports retrofit applications where existing routing space is limited yet a reliable data link is required.

Dynamic flex applications require verified mechanical endurance. The RKB0016 is rated for 5 million flex cycles and is validated on a test radius of 7.5 × D during dynamic motion. For static dress-pack routing, the allowable bend tightens to 5 × D, enabling compact cabinet layouts without exceeding conductor strain limits. Signal integrity is maintained through a shielded four-core construction that terminates with an M8 A-coded 4-pin plug on one end and a matching M8 A-coded 4-pin socket on the other. The cable is listed as the basic model, indicating a standard outer jacket and conductor cross-section suited to typical in-plant bus lengths.

For environments where assembly time is limited, the cable is supplied as a ready-made harness built as a system bus cable, removing the need for on-site crimping. It remains flexible from -30 °C during cold-start conditions up to 80 °C in continuous service, so the same part can be routed through unheated loading zones and warm control enclosures. Identical storage limits of -30 °C to 40 °C allow spares to be kept in ordinary stockrooms without special climate control, helping preserve consistent dielectric performance when the cable is placed into service.
