Product Description:
The RKL4740 is a motor-power cable produced by Bosch Rexroth Indramat for the RKL Motor Power Cables series. It carries three-phase drive power and auxiliary control cores between IndraDrive amplifiers and synchronous motors, so machinery can execute coordinated motion while the cable moves inside energy-chain systems. The assembly is engineered specifically for continuous-flex environments found on gantries, pick-and-place modules, and articulated robots that demand reliable power delivery under constant mechanical stress.
Mechanical endurance is defined by a service life of 5,000,000 flex cycles, allowing long deployment before scheduled replacement. When permanently fixed, the cable can be bent to a radius of only 5 x D; in moving tracks the minimum safe bend expands to 7.5 x D, reducing conductor strain during acceleration. A tough PUR jacket shields the cores against oil, coolant, and weld spatter, while maintaining flexibility at low temperatures. Overall diameter is 25.5 mm, so routing space in cable chains and glands can be calculated precisely.
Electrical characteristics complement the mechanical design. Copper resistivity of 1.21 Ohm/km limits I²R losses over typical axis-length runs, and the internal bundle follows the INK0606 bulk-cable specification used throughout Rexroth harness kits for consistent impedance. Four dedicated signal pairs—identified here as 4 control conductors—permit temperature or brake feedback to share the same jacket, reducing wiring complexity. The main power trio employs a 16.0 mm² cross-section to handle the high currents drawn by medium-frame servo motors without excessive voltage drop.
