Product Description:
The RKL4309 cable is manufactured by Bosch Rexroth Indramat within the RKL Motor Power Cables series and is intended to link servo drives to motors while carrying both power and auxiliary control signals in dynamic automation axes. Its PUR jacket, colored to RAL 2003 orange, resists cutting fluids and provides an adhesion-free matte surface that slides through energy chains without sticking or abrasion.
The mechanical rating reaches 5,000,000 bending cycles, which indicates the number of flex motions the cable endures before conductor fatigue becomes likely in continuous-motion carriers. When routed statically it may be bent to a minimum of 5 × D, whereas moving installations must observe the larger 7.5 × D radius to avoid shield or insulation damage. Power is transmitted through copper cores of 2.5 mm²; this cross-section limits resistive losses and voltage drop on medium-length runs. Four smaller control pairs, each sized at 1.0 mm², convey brake and temperature signals so that drive diagnostics remain reliable even under motor vibration.
Factory-fitted connectors simplify installation: the motor side terminates in an RLS1201 angled plug, while the drive end carries an RLS0721 straight plug that fits IndraDrive power modules without adaptation. Inside the PUR sheath there are 4 numbered control conductors laid concentrically around the power trio to maintain consistent impedance and minimise crosstalk. The overall diameter is only 14.8 mm, allowing tight routing through cable chains and machine frames while leaving space for feedback and pneumatic lines. Jacket elasticity, combined with oil resistance, supports reliable service in packaging machines, gantries, and pick-and-place robots.
