Product Description:

The RKL0064 power cable is a flexible interconnection product manufactured by Bosch Rexroth Indramat within the RKL Motor Power Cables series. It links servo drives to motors and auxiliary control circuits, carrying high-current phases and low-level control cores so that motion axes receive regulated energy inside automated machinery. By combining motor power and auxiliary conductors in one jacket, it reduces the need for separate cable runs along moving axes. Its flexible construction supports repeated movement in cable tracks, robot arms, and other machine sections where stationary wiring would not perform reliably.

The cable is rated for 5,000,000 bending cycles, so it can withstand repeated articulated motion before fatigue limits are reached. During combined flexing and twisting, it tolerates a torsional load of ±180°/30 cm, which suits routing through rotary axes and other moving assemblies. This torsional capability helps reduce mechanical stress when the cable is exposed to frequent reversing motion. The copper power cores have a cross-section of 35.0 mm², providing the current-carrying capacity needed for motors that operate from the cable's rated 300 V system. When the cable is in motion, a bending radius of 7.5 × D, with D representing the outer diameter, must be maintained to protect the insulation and conductor bundle.

For stationary runs, the minimum bend is 5 × D, allowing compact routing without overstressing the sheath. Two control cores with a cross-section of 1.5 mm² run alongside the four power conductors and can carry brake or thermal sensor signals. The controller end uses a RLS0750 connector, while the motor side uses a RLK1301 plug. The cable supports drag-chain motion and contains no halogen additives, which helps limit corrosive gas release during a fire. It is suited to packaging lines, gantries, and pick-and-place systems that require continuous cable movement through confined routing paths.
