Product Description:
The RKL4408 cable is produced by Bosch Rexroth Indramat within the RKL Motor Power Cables series and is intended to carry drive power and auxiliary signals between IndraDrive converters and their associated motors. Its construction is tailored for dynamic machine axes, where a rugged yet flexible cable preserves servo performance under continuous motion and repeated bending in cable chains.
The power section employs 4x10.0 mm² conductors to deliver rated current with low voltage drop, while paired auxiliaries of 2x1.0 mm² + 2x1.5 mm² accommodate brake release and temperature sensor circuits. A matte, adhesion-free PUR sheath resists cutting oils and weld spatter, and the bright RAL 2003 orange jacket makes moving runs visible inside guards. Overall diameter is only 22.2 mm, which helps minimise tray space in compact machines. AEH ferrules are factory-crimped on the motor end and RKS ring terminals are fitted for cabinet ground points, reducing on-site termination time.
Electrical rating supports 300/500 V for power according to VDE and 600 V AC per UL, while the separate control cores are approved for 300/300 V VDE and 600 V AC UL. The cable remains mobile from -20 to +40 °C and can stay fixed down to –30 °C, suiting indoor gantry and palletiser zones. During continuous flexing it tolerates a minimum bend radius of 7.5xD, so tight loops in drag chains do not strain the cores. Classified as bulk type INK0605, the design matches Rexroth wiring tables for EMC and capacitance, and the glossy orange jacket colour aids maintenance crews tracing circuits.
Wake Industrial offers a 1-year warranty on every RKL4408, and same-day shipping is available for time-critical orders. Customers can use the free chat tool to ask about type codes, fault listings, or general specifications.
