Product Description:
The RKL4781 is a motor power cable developed by Bosch Rexroth Indramat within the RKL Motor Power Cables series. The cable links the controller side to Rexroth synchronous motors, transferring three-phase power and ancillary signals in automated machinery. Its construction is optimized for drag-chain movement and harsh plant environments, making it a reliable interconnect component in industrial automation.
Inside the sheath, the bulk cable type is INK0602, indicating compliance with Rexroth routing and torsion limits. Eight conductors are arranged as 4x2.5 mm² + 4x1.0 mm², so power cores carry higher current while paired control cores support temperature or brake circuits. The dedicated power wires each have a cross-section of 2.5 mm², limiting voltage drop over long runs, whereas the control cores are sized at 1.0 mm² for signal integrity. Copper strands exhibit a conductor resistance of 7.98 Ohm/km at 20 °C, a parameter used when calculating I²R heating in continuous duty.
Electrical behavior toward ground is characterized by a discharge capacity of 0.7 nF/m, useful when estimating drive-generated switching currents. On the cabinet end the preassembled RLS0723/K03 connector mates with IndraDrive controllers, while the motor side terminates in a keyed WEF/RKS bayonet fitting that locks against vibration. A PUR (adhesion-free, matte) outer jacket resists coolant, oil, and abrasion, and its RAL 2003 orange color assists in quick visual identification during service.
