Product Description:

The RKB0037 cable is produced by Bosch Rexroth Indramat within the RKB Control Cables series. It is supplied as a factory-terminated system bus cable that links drive amplifiers, I/O stations, and supervisory controllers in distributed automation systems. The terminated assembly plugs directly into compatible bus nodes without requiring additional crimping or soldering. By maintaining signal integrity along dynamic machine axes, the cable supports coordinated motion and status exchange among interconnected devices.

In repetitive flexing installations, the jacket and conductors are rated for 5,000,000 bending cycles, a durability level suited to gantry robots and cable tracks where the line moves thousands of times during each shift. Signal continuity is further protected by factory-installed D-Sub 9-pin connectors, which eliminate variations associated with field wiring. During motion, conductor stress is limited by a dynamic bend radius of 7.5 × D; using a loop that meets or exceeds this value helps prevent microcracking in the insulation. The cable continues to transmit data at ambient temperatures as low as -30 °C. It remains stable at temperatures up to 80 °C, covering a broad range of factory floors and machine enclosures.

When installed in a stationary tray, the cable permits a 5 × D static bend radius, allowing compact routing inside control cabinets without excessive strain. Data channels are mapped through 9 individual conductors, matching the transceiver pinout and simplifying continuity checks. Compliance with the HNA protocol provides the impedance and shielding needed for high-speed multidrop communication. Because it is delivered as a ready-made assembly in the Basic model variant, the cable can be ordered under one part number instead of requiring separate bulk wire, connectors, and assembly tooling. The cable may be stored between -30 °C and 40 °C without affecting its electrical or mechanical properties.
