Product Description:

The RKL4569 motor power cable is produced by Bosch Rexroth Indramat as part of the RKL Motor Power Cables series. It carries three-phase drive power and auxiliary control conductors between IndraDrive inverters and servomotors, and its mechanical design permits routing through fast-moving cable chains on automated machinery.

The cable can work in enclosures that reach up to 80 °C and remain flexible down to -30 °C, giving a broad operating window for heated production cells or refrigerated conveyors. A nominal outside diameter of 25.5 mm simplifies gland selection while leaving space for the shielding and drain required for EMC compliance. The copper power cores each have a cross-section of 16.0 mm², providing low voltage drop on long runs, and the outer sheath is extruded from abrasion-resistant PUR, so chips and lubricants do not degrade the insulation.

Mechanical service life is verified for 5,000,000 flex cycles, and the dynamic bend radius of 7.5 × D keeps conductor strain within specification during constant motion; for static trays the radius may be reduced to 5 × D. A mutual capacitance of 1.2 nF/m limits reactive current at high PWM frequencies, while conductor resistance is only 1.21 Ω/km at 20 °C, supporting efficient power transfer. Two twisted control pairs listed as 2x(2x1.5 mm²) are integrated for temperature or brake signals, eliminating the need for a second cable in compact drag-chain layouts.
