Product Description:
The RKL4733 is a motor power cable manufactured by Bosch Rexroth Indramat within the RKL Motor Power Cables series. It routes drive output from Rexroth controllers to servomotors, combining three-phase power conductors with integrated feedback and brake lines so that a single assembly handles energy and monitoring in automated machinery.
Four stranded copper cores of 4 x 10.0 mm² deliver the main phase current, while a PUR jacket keeps the overall diameter to 22.2 mm for compact routing in energy chains. When clamped in fixed runs the cable only needs a bending radius of 5 x D, and in constantly moving carriers it maintains full functionality down to 7.5 x D. Dynamic design verified for 5,000,000 bending cycles means service life is preserved in high-duty gantry or pick-and-place axes where continuous flexing occurs.
Two auxiliary cores sized at 2 x 1.5 mm² support contactor coils or brake release circuits, and a separate pair of 2 x 1.0 mm² control conductors can carry temperature or status signals without additional harnesses. The line-to-line capacitance of 1.0 nF/m helps keep switching losses predictable for the drive, while low DC resistance of 1.91 ohm/km limits voltage drop on long runs. Factory-installed connectors—RLK1401 on the motor side and RLS0721 at the controller—match IndraDrive pinouts, and the matte, adhesion-free PUR sheath resists oil and abrasion. Bulk length is supplied from INK0605 master reels to suit custom cable sets.
Wake Industrial stocks this cable, offers same-day shipping on qualifying orders, and keeps quotations valid for 30 days to streamline maintenance planning.
