Product Description:
The Bosch Rexroth Indramat RKL0011 is a motor power cable from the RKL Motor Power Cables series. Designed to supply three-phase power between drive controllers and synchronous servo motors, it supports machine tools, packaging lines, and other automated equipment where flexible routing is required. The cable is supplied as a preassembled harness, reducing installation time by providing the necessary conductors and terminations in one assembly.
At its core, the cable uses bulk cable type INK0602, which establishes the insulation system and conductor arrangement. The conductor configuration of [4x2.5 mm² + 2x(2x1.0 mm²)StC]C combines four power cores for the phases and protective ground with two shielded signal pairs. This arrangement allows the cable to carry motor power together with brake or temperature sensor signals. An electrical resistance of 7.98 Ω/km limits voltage drop over long cable runs, while an outer diameter of 14.8 mm allows the cable to fit standard cabinet glands. A matte, adhesion-free PUR jacket resists coolants and abrasion during continuous-flex operation. Its orange RAL 2003 color improves visibility in crowded cable trays and machine enclosures. For a stationary installation, the cable may be routed with a minimum bend radius of 5 × D, allowing it to fit into confined spaces without placing excessive stress on the conductors.
During motion, the cable uses a minimum dynamic bending radius of 7.5 × D to help prevent conductor fatigue in drag chains and other moving cable routes. The factory-installed motor-side RLS1201 connector and drive-side RLS0721 connector provide strain-relieved terminations that simplify installation and reduce mechanical loading at the connection points. A discharge capacity of 0.7 nF/m indicates the cable’s capacitive coupling to ground, which is an important consideration for controlling electrical noise from high-frequency inverter outputs. The shielded auxiliary conductors help separate low-power brake or temperature signals from the motor phase currents while the cable moves through automated machinery.
