The Bosch Rexroth Indramat RKL4313 is part of the RKL Motor Power Cables series and features 8 conductors with power conductor cross-sections of 4.0 mm². This cable supports 5 million bending cycles and can operate in temperatures from -30 to 80 degrees Celsius. It uses INK0603 bulk cable and includes RLS0722/K04 and RLS1201/C04 connectors for controller and motor sides.

Product Description:
The RKL4313 is a flexible motor-power cable produced by Bosch Rexroth Indramat within the RKL Motor Power Cables series. It forms the electrical link between IndraDrive controllers and synchronous motors, carrying phase current, protective earth and auxiliary supplies while tolerating continuous motion in cable tracks used on gantries, pick-and-place axes and other automated machinery.
The cable contains eight cores: three phase lines and PE plus two auxiliary pairs. The power set is rated at 4.0 mm² and organized as 3 + PE to match the current draw of MSK and MAD motors. Control functions are supported by conductors 5 and 6, each sized 1.0 mm², and all elements are stranded inside bulk type INK0603 insulation for oil resistance. A dynamic service loop is aided by a bending radius of 7.5xD; this specification limits mechanical stress where the cable passes through energy-chain carriers. Factory-fitted connectors simplify installation: the controller end terminates in RLS0722/K04 while the motor end uses RLS1201/C04.
For stationary routing the cable may be set on a static radius of 5xD, and test data confirms durability through 5000000 bending cycles in continuous flex applications. Conductors 7 and 8 increase auxiliary capacity with a cross-section of 1.5 mm², allowing brake release or temperature-sensor circuits to share the sheath. The operating envelope is specified at -30 to 80 °C, a range mirrored by identical storage limits, so the assembly need not be conditioned before commissioning. Overall construction remains compact despite the eight-conductor layout, enabling easy routing through machine frames.
