Product Description:

The RKL4707 is a flexible motor power cable produced by Bosch Rexroth Indramat within the RKL Motor Power Cables series. It is intended to link IndraDrive controllers to servo motors in dynamic machine axes, carrying three-phase power and auxiliary signals while tolerating continuous motion on energy-chain systems found in automated assembly lines and packaging machines.

The cable core supports up to 5,000,000 flex cycles, allowing long service life in high-duty chains. For moving applications its minimum dynamic loop is limited to 7.5 x D, whereas fixed routing can observe a tighter static bend of 5 x D. A robust outer sheath of PUR resists cutting oils and weld spatter, and the overall bundle measures only 17.0 mm in diameter, easing installation through narrow guides.

An embedded drain conductor gives the line a discharge capacity of 0.8 nF/m to control common-mode noise between drive and motor. Power transmission is handled by copper cores of 4.0 mm², supplemented with two pairs for temperature sensors and brakes; pairs 5–6 are 1.0 mm² and pairs 7–8 enlarge to 1.5 mm² for signal integrity. Quick-lock terminations are supplied at each end: the controller interface uses RLS0721/K04 while the motor is mated with RLK1201, allowing tool-free connection during maintenance exchanges.

Wake Industrial stocks this cable, offers same-day shipping on qualifying orders, and backs every purchase with a 1-year warranty. For clarification of fault codes, pin assignments, or manufacturer data, customers can consult the free chat tool at any time.
