Product Description:
The IKG4020 cable is manufactured by Bosch Rexroth Indramat as part of the IKG Motor Power Cables series. It supplies servo motors with three-phase power while carrying brake or sensor signals through dedicated control pairs, streamlining installation in automated handling, packaging, and machining equipment. Its fine-stranded conductors and flexible sheath permit tight bending radii, enabling compact routing inside cable carriers and reducing the amount of cabinet space required in industrial automation cells.
The cable has a bending life of 5,000,000 cycles, enabling repeated motion inside drag chains without causing premature conductor fatigue. The copper cores have a loop resistance of 19.5 Ω/km at 20 °C, so voltage drop over moderate cable runs remains low. Four power cores with a conductor layout of 4 × 1.0 mm² carry the motor phase current and are insulated for a circuit voltage of 300/500 V. All cable elements are enclosed by a durable PUR outer jacket that resists cutting oils and weld spatter in industrial environments. Two twisted control pairs, each with a conductor cross section of 0.75 mm², are arranged concentrically between the power conductors to carry brake-release or thermal-sensor signals with minimal crosstalk. The cable supports fixed routing and dynamic festoon service without compromising its electrical performance.
The continuous conductor temperature can reach +90 °C in fixed routing or +80 °C during flexing. Installation is permitted at temperatures as low as -30 °C without causing the cable jacket to become brittle. The cable has a circular profile with an outer diameter of 12.0 mm, simplifying installation through metric cable glands and supporting high-density cabinet layouts. In stationary cable trays, the maximum ambient operating temperature is +40 °C. The control pairs are insulated for 300/300 V, making them suitable for typical brake or sensor circuits. The separate power and control conductors allow motor current and auxiliary signals to travel through a single cable assembly while maintaining the required electrical isolation.
