Product Description:
The RKB0020 is a flexible data and control lead in the RKB Control Cables series from Bosch Rexroth Indramat. Intended for high-speed fieldbus segments, it links drives, I/O stations, and PLCs that communicate over Sercos III networks. The cable maintains reliable Ethernet-based messaging while enduring repetitive cable-track motion common in automated assembly lines and gantry systems.
Mechanically, the RKB0020 is rated for 5000000 continuous bending cycles, a figure that defines how many chain traverses it withstands before conductor fatigue becomes critical. It carries signals on the Sercos III physical layer and meets Ethernet performance through its CAT.5 classification, supporting deterministic telegram timing. Both ends terminate in a straight-oriented RJ45 plug with eight gold-plated contacts; the numeric 8 denotes the signal positions available for differential pairs, power, or service lines. Shielding surrounds the twisted pairs to attenuate electromagnetic interference, and a static bending radius of 5×D prevents kinking where the cable is fixed routed.
For dynamic machine axes the lead may flex around a radius down to 7.5xD during motion without data loss. The temperature envelope during operation spans -30 °C to 80 °C, enabling installation in refrigerated cells or warm control enclosures; during storage it remains stable between –30 °C and 40 °C. Straight connectors simplify panel penetration, and the fully shielded construction maintains CAT.5 crosstalk limits even under servo-inverter noise. Five-million-cycle endurance and 5×D static curvature together ensure long service intervals in energy-chain layouts.
Wake Industrial stocks this cable and can arrange same-day shipping when production schedules demand it. Every purchase is covered by a 1-year warranty starting on the shipment date. Price quotations remain valid for 30 days, giving maintenance teams time to finalize procurement.
