Product Description:
The IKG4118 is a motor power cable manufactured by Bosch Rexroth Indramat for the IKG Motor Power Cables series. It is intended to transmit three-phase power and control voltages between an IndraDrive controller and a synchronous servo motor in installations where the cable is constantly flexed. Stranded copper cores and a robust outer jacket let the assembly endure bending inside pick-and-place machines, gantries, and packaging cells. Its integrated signal pairs allow temperature sensor or brake lines to share the same routing, reducing cabinet wiring and simplifying machine layouts.
A mechanical endurance rating of 5 million bending cycles qualifies the cable for continuous drag-chain duty, and this rating is achieved with the INK0604 bulk cable that forms the basis of the finished lead. The internal layout, specified as 4x6.0 + (2x1.0)StC + (2x1.5)StC, keeps the power cores separated from shielded control pairs to minimise crosstalk. Direct current losses are limited by a conductor resistance of 3.30 Ω/km measured at 20 °C, supporting low voltage drop on long runs. For cabinet termination, the controller end is supplied with an RLS0721/K06 angled connector, and the assembly is approved for drag-chain use, eliminating the need for additional strain-relief fittings.
At the motor end an INS0481/C06 bayonet connector mates quickly with Indramat servo housings, and the separate control wires provide 2 x 1.0 mm² leads for sensors plus 2 x 1.5 mm² cores for a brake coil. The outer sheath is coloured RAL 2003 (orange) to indicate low-voltage motor power in European machinery, while the underlying material is abrasion-resistant PUR that resists coolants and oils. A nominal outer diameter of 18.5 mm fits standard chain dividers, and each power conductor uses a cross-section of 6.0 mm² to deliver rated current without excessive heating. Together, these characteristics balance electrical performance with compact size, allowing the cable to operate reliably alongside high-speed axes and frequent start-stop duty.
