Product Description:
The RKL4335 motor power cable is manufactured by Bosch Rexroth Indramat and belongs to the RKL Motor Power Cables series. It is supplied as a pre-terminated assembly intended for servo-axis wiring inside industrial automation systems, where it conveys three-phase supply and auxiliary control signals between a drive controller and the connected motor while tolerating constant motion in energy-chain environments.
The cable is engineered for up to 5,000,000 bending cycles, allowing long service life in high-duty production cells. During operation in a carrier, its dynamic bending radius is limited to 7.5 x D, preventing conductor fatigue at tight loop points. Core geometry follows the INK0650 bulk cable designation, so electrical parameters match other Rexroth leads of the same class. Factory moulded terminations include a motor-side connector coded RLS1301/C03 and a drive-side connector coded RLS1302/C03; both housings lock with standard Rexroth bayonet couplings to maintain shielding continuity. For rotary tables or robotic wrists the construction endures torsional load of ±180°/30 cm, keeping impedance stable even under repeated twist.
The design is rated for drag-chain use, and its static bending radius is 5 x D when fixed, simplifying tight cabinet routing. Power conductors employ a cross-section of 1.5 mm² while the separate control pair is sized at 0.75 mm², supporting brake release or encoder reference lines without voltage drop. A halogen-free outer jacket limits corrosive gas release during thermal events and meets clean-room safety goals. Combined with its defined torsion and bend limits, these attributes give the RKL4335 predictable electrical behaviour and mechanical durability in packaging machines, pick-and-place gantries, and other high-speed motion platforms.
