Product Description:
The RKH0215 is a hybrid motion-control cable manufactured by Bosch Rexroth Indramat for the RKH Hybrid Cables series. It combines power conductors with signal pairs inside a single jacket, allowing drives and motors to be connected through one assembly instead of separate power and feedback leads. In automated machinery, this arrangement reduces wiring volume and simplifies routing where multiple conductors must travel along the same path. The integrated design also helps maintain consistent electrical characteristics during the repeated movement associated with drag-chain applications.
The cable is rated for 5,000,000 flexing cycles, allowing it to operate in high-duty energy chains without premature conductor fatigue. A dynamic bend radius of 10 × D is the minimum permitted loop while the machine is moving. A static bend radius of 5 × D applies when the cable is clamped or remains stationary. The drive side uses an RHS0011 plug, while the motor side uses an RHS0016 receptacle. These keyed interfaces prevent reversed connections and maintain shielding continuity through the hybrid junction. The combination of long flex life and controlled bend radii supports routing through articulated carriers, linear axes, and rotary tables without placing excessive mechanical stress on the internal conductors.
The conductor bundle uses the raw-cable reference REH0800, which covers the conductor cross sections, insulation materials, and screen density used in the assembly. Continuous operation and storage are permitted from -40 °C to 80 °C, allowing the cable to remain flexible in refrigerated production cells while tolerating elevated temperatures near inverters. A braided screen helps preserve signal integrity by limiting electromagnetic interference between the power conductors and feedback circuits. Shield drains and filler cords support the internal conductors while helping the bundle retain its shape during repeated motion. An external PUR jacket protects the cable from abrasion and provides a durable surface for movement through energy chains. Proper strain relief prevents connector loads from being transferred to the conductor terminations during acceleration, reversal, or sustained machine vibration.
