Product Description:

The RKL4327 is a motor power cable produced by Bosch Rexroth Indramat as part of the RKL Motor Power Cables series. It couples drive controllers to servo motors in automated machinery, providing synchronized power and control conductors that stay reliable during high-speed motion axes. The pre-assembled cable arrives factory-terminated to significantly reduce installation time on busy assembly lines.

The cable is rated for 5,000,000 bending cycles, indicating its suitability for continuous-flex applications such as energy chains. It is fabricated from INK0603 bulk stock, and its conductor bundle follows the composition 4×4.0 + 2×1.0 + 2×1.5 mm²; the primary phase cores each use a cross-section of 4.0 mm², allowing standard servo currents without overheating, while the auxiliary control pairs are sized at 1.0 mm² and 1.5 mm² for sensors and brakes. A measured line resistance of 4.95 Ohm/km limits voltage drop over long runs, while an overall diameter of 17.0 mm keeps routing channels compact in multi-axis gantries and demanding machine tools.

Mechanical integration is clarified by a dynamic bend requirement of 7.5 × D, allowing carriers to be dimensioned without excessive strain, and a stationary radius of 5 × D for fixed routing inside cabinets. The pre-assembled controller plug RLS0722/K04 mates directly with IndraDrive power terminals, while the motor end uses an angled RLS1301/C06 connector that locks with the housing seal to maintain IP ratings. A PUR outer jacket, adhesion-free and matte, in orange RAL 2003 resists oil and abrasion, and a low discharge capacitance of 0.8 nF/m minimizes drive-induced leakage currents.

Wake Industrial stocks the RKL4327 cable for immediate procurement. Same-day shipping options are available when downtime must be minimized. Customers may use the free chat tool to ask about type codes, conductor design, or other general specifications.
