Product Description:
The RKL4433 cable is produced by Bosch Rexroth Indramat as part of the RKL Motor Power Cables series. It is a multi-core power and control lead intended for servo-drive installations in industrial automation. The cable links stationary cabinets to moving motors, carrying drive current and low-voltage control signals while tolerating continual motion and fixed routing conditions common in gantry axes, conveyors, and packaging machinery.
Its overall jacket diameter is 18.5 mm, and the copper arrangement includes 4x6.0 mm² power conductors supported by separate control pairs of 1.0 mm² and 1.5 mm² cross-section. The construction limits capacitive load on the drive to 0.8 nF/m, reducing reactive current at high PWM switching frequencies. Drive supply voltage up to 300/500 V can be applied on the power cores, while the control pairs operate at 300/300 V. When the cable is installed permanently, routing can follow a minimum bending radius of 5 x D; dynamic applications must respect a 7.5 × D radius to avoid conductor fatigue.
The power core resistance is 3.30 Ω/km, keeping voltage drop low on long runs between cabinet and motor. An outer sheath in RAL 2003 (orange) improves visibility, and the material specification of PUR (adhesion-free, matte) provides abrasion resistance, oil tolerance, and smooth travel in drag chains. Fixed routing is permissible in ambient air from -30 to +40 °C; moving applications can be operated from −20 °C up to +40 °C. Conductor temperatures may reach 90 °C in static use and 80 °C during continuous flexing without compromising insulation integrity. These thermal ratings, combined with the flexible and fixed bend limits, let the RKL4433 serve reliably in motor circuits that experience both stationary cabinet wiring and repetitive machine motion.
Frequently Asked Questions about RKL4433:
Q: What is the configuration and size of the power cores in the RKL4433 cable?
A: The RKL4433 cable is designed with power cores sized at 4x6.0 mm² for effective power transmission.
Q: What kind of jacket material and color does the RKL4433 cable feature?
A: This cable uses a PUR jacket in RAL 2003 orange, which is adhesion-free and matte for durability and visibility.
Q: What are the minimum bend radius values for fixed and flexible installations of the RKL4433 cable?
A: The minimum bend radius for the RKL4433 is 5 times the cable diameter when fixed and 7.5 times the diameter when flexed.
Q: What ambient temperature ranges are supported by the RKL4433 cable during flexible and fixed use?
A: RKL4433 maintains flexibility in ambient temperatures from -20 to +40 °C and for fixed installations from -30 to +40 °C.
Q: What are the operating voltages for the power and control cores of the RKL4433 cable?
A: The operating voltage for the power cores on the RKL4433 is 300/500 V, while the control cores operate at 300/300 V.
