Product Description:
The RKB0049 is a flexible control cable produced by Bosch Rexroth Indramat within the RKB Control Cables series. Designed for signal exchange between distributed servo drives and higher-level controllers, it routes fieldbus communication along dynamic machine axes. By combining machine-mountable M12 connectors with a finely stranded conductor bundle, the cable transmits control data while tolerating constant motion in cable carriers commonly found in automated assembly lines and transfer systems.
The cable is rated for 3,000,000 bending cycles, meaning it can traverse a carrier repeatedly before conductor fatigue becomes critical in normal dynamic service. It carries the S-BUS protocol, so shielding and impedance are matched to drives that rely on this serial interface. A maximum axial pull of 60 N can be applied to the jacket or the molded connectors without damaging crimps or conductors, which helps during installation through long drag chains. Sealed coupling nuts and over-molds provide an IP67 barrier, allowing temporary submersion or spray-down cleaning in production cells. During standstill, insulation materials remain stable up to 85 °C, so the cable can be routed near motors or braking resistors that radiate heat when idle.
When the axis is moving, the thermal limit drops to 50 °C, a threshold chosen to prevent plasticizers from migrating under repetitive flexing. Continuous carrier travel is permitted with bend radii as tight as 5× cable diameter, supporting compact routing inside small energy chains. For cold-storage or winter startup conditions, the polymer sheath stays flexible down to -30 °C while idle and down to 0 °C during motion. Cable carrier compatibility is confirmed, and both ends terminate in matched M12 axial sockets to maintain data integrity along the full cable run.
