Product Description:

The IKG4168 motor power cable is manufactured by Bosch Rexroth Indramat for the IKG Motor Power Cables series. In automated machining centers, packaging lines, and handling systems, this cable links an inverter to its motor while carrying three-phase power and the auxiliary circuits required for brake release or temperature sensing. Its layout and materials maintain signal integrity and mechanical reliability during continuous motion in industrial machinery.

The cable transmits energy through 4 × 10.0 mm² copper power conductors that accommodate typical servo motor currents. Its 300/500 V voltage rating indicates the permissible line-to-ground and line-to-line potentials. An outside diameter of 22.2 mm balances current-carrying capacity with the routing space available inside cable carriers. The outer sheath is made of PUR, a thermoplastic polyurethane selected for resistance to abrasion, oil, and coolant. The sheath is colored RAL 2003 (orange) for clear identification in bundles containing multiple cables. Conductor resistance is limited to 1.91 Ω/km, helping reduce internal heat generation and voltage loss over long cable runs. Two auxiliary pairs with conductor sizes of 1.0 mm² and 1.5 mm² support brake, sensor, or protective grounding circuits without requiring a separate cable.

The cable has a dynamic service life of 5,000,000 bending cycles, allowing the assembly to withstand repetitive movement in high-speed drag chains. A fixed installation requires a minimum bend radius of 5 × D, while a moving application requires a minimum bend radius of 7.5 × D to reduce conductor fatigue. The cable is approved for drag-chain use in automated equipment with continuously moving axes. Its temperature limit reaches 90 °C in fixed installations, allowing routing near motors and drives that radiate heat. During flexing, the cable supports temperatures up to 80 °C while retaining the flexibility needed for repetitive machine motion.
