Product Description:

The RKL4340 is a factory-terminated motor power cable from Bosch Rexroth Indramat and belongs to the RKL Motor Power Cables series. It is intended for fixed or flexing installation between drive controllers and synchronous motors, where it delivers three-phase power together with two screened control pairs to encoder brakes or temperature sensors. By combining robust PUR sheathing with screened conductors, the assembly supports reliable signal integrity and electromagnetic compatibility in industrial automation lines.

During motion the cable may be bent down to a dynamic radius of 7.5 × D, while stationary loops can be formed at a tighter 5 × D; these limits protect the copper stranding from fatigue. A nominal outside diameter of 25.5 mm allows straightforward routing through standard drag-chain separators, and the loop resistance of 1.21 Ω/km at 20 °C keeps voltage drop low on long runs. For the power cores the jacket withstands up to 600 V AC, matching the output of IndraDrive inverters and preventing insulation breakdown under rated operating voltage.

The bulk cable type is designated INK0606 and is pre-fitted with a motor end connector RLS1301/C16 and a drive end counterpart RLS1302/C16 to eliminate field crimping. Its outer sheath is coloured RAL 2003 (Orange) for quick identification in mixed cable trays, and the PUR material resists oil, coolant, and abrasion. Internal geometry combines a 4 × 16 mm² power set with 2 × (2 × 1.5 mm²) shielded control pairs; this construction yields a capacitive coupling of 1.2 nF/m, a parameter relevant for drive filter design. The cable is not suited for torsional applications but supports repeated flexing along a single axis.

Wake Industrial can arrange same-day shipping on this model, and international shipping options are also available. All purchases carry a 1-year warranty for added procurement confidence. In addition, quotations for the RKL4340 remain valid for 30 days to assist with budget approval cycles.
