Product Description:
The RKH0900 hybrid cable is manufactured by Bosch Rexroth Indramat as part of the RKH Hybrid Cables series. It combines motor power conductors and digital encoder lines in a single sheath, streamlining wiring between IndraDrive controllers and synchronous servo motors. In industrial automation, a dedicated hybrid cable reduces panel space, simplifies material tracking, and decreases the number of separate cable routes required between the drive and motor. Combining these circuits also makes it easier to route wiring through confined machine frames, articulated assemblies, and cable carriers. The integrated arrangement supports applications that require both motor current and dependable feedback transmission along the same axis.
This model comes in a ready-made configuration, so it arrives cut and terminated for immediate installation. Its internal geometry follows a hybrid design, allowing the power conductors and feedback pairs to coexist while maintaining the shielding needed for dependable position data. The cable supports power and encoder transmission, eliminating the need to install parallel discrete cables for these functions. On the motor side, the harness ends in a keyed RHS2321 circular connector. Its plastic insert separates the high-current pins from the low-voltage encoder contacts, helping prevent accidental contact between the two circuits during connection or removal. A basic mechanical design keeps the outer diameter moderate, which supports drag-chain routing in compact machinery without adding unnecessary bulk around moving assemblies.
The cable has a mechanical endurance rating of 5,000,000 dynamic flexing cycles, making it suitable for axes that move repeatedly during normal machine operation. During dynamic use, the jacket can bend repeatedly around a radius of 10 × D without placing excessive strain on the internal conductors. Stationary installations permit a tighter bend radius of 5 × D, allowing the cable to fit fixed routes where available space is limited. The second end carries an RHS2322 connector that mates with cabinet-mounted drive ports and is clock-aligned with the first plug for easier orientation. The operating temperature range extends from -40 to +80 °C, supporting use in refrigerated processing areas and high-temperature industrial environments. These temperature limits allow the jacket and internal insulation to remain functional across a broad range of machine locations without accessory heating or cooling sleeves.
