Product Description:
The IKG4140 is a motor power cable manufactured by Bosch Rexroth Indramat for the IKG Motor Power Cables series. It links drive controllers to servomotors and carries phase current, protective grounding, and auxiliary signals for brake or temperature circuits in industrial automation cells. A polyurethane outer jacket protects the conductors from cutting oils and repeated motion, allowing the cable to be routed through machine frames, cable trays, or energy chains without additional armor.
The cable has an overall diameter of 12.2 mm, which must be considered when selecting cable glands and allocating space in drag-chain cavities. Its conductor bundle uses a 4 × 1.5 mm² + 2 × (2 × 0.75 mm²) layout, providing three power phases, a protective ground conductor, and paired auxiliary cores. The direct-current resistance is limited to 13.3 Ω/km, helping reduce voltage drop between the controller and motor on long cable runs. The paired control cores support reliable auxiliary signal transmission while maintaining the flexibility needed for moving machinery. A PUR (adhesion-free, matte) sheath resists abrasion, cooling lubricants, and hydrolysis during washdown cycles. In moving applications, the insulation system supports conductor temperatures up to 80 °C, while the stranded copper construction accommodates repeated bending.
The controller end uses an RLS0722/K02 connector set, while the motor end uses an INS0481/C02 angled connector that fits confined mounting spaces. In fixed installations, the conductors can operate at temperatures up to 90 °C because the cable is not exposed to continuous flexing. During repetitive motion, the cable can bend to a minimum radius of 7.5 × D, allowing it to pass through an energy chain without placing excessive stress on the conductor cores. Internal fillers maintain the cable’s concentric geometry during drag-chain operation, helping prevent conductor displacement as the assembly moves. The adhesion-free, matte surface also reduces friction against adjacent cables and carrier partitions during repeated travel.
