Product Description:

The RL2-042EBB is a motor power cable manufactured by Bosch Rexroth Indramat for the RL2 Motor Power Cables series. It serves as the dedicated power link between a second-generation Rexroth servo motor and its drive, carrying phase and protective grounding conductors through a V-style M40 plug connector. Within automated machinery, it belongs to the Rexroth Cable product group and is intended for installations where continuous motion and tight routing spaces coexist. Its flexible design supports cable routing through moving machine assemblies where rigid wiring would be unsuitable.

The conductor set is arranged as 4 × L + 4 × 0.75 mm², and each load core has a cross-sectional area of 2.5 mm², giving the assembly a current capacity suitable for mid-frame servo axes. A PUR jacket in Orange RAL 2003 resists oil and weld spatter while maintaining flexibility. The cable has an outer diameter of 14.8 mm, which eases routing through drag chains and machine glands. At 20 °C, the insulation resistance remains above 20 MΩ/km, supporting low-loss power delivery over extended cable lengths. The cable has a Basic design without additional shielding or hybrid cores, simplifying termination and reducing overall weight. Its conductor arrangement separates the primary motor power cores from the smaller auxiliary conductors used by the connected motor assembly.

Mechanical life is rated for 5,000,000 bending cycles, allowing the cable to accommodate high-duty carrier motion without premature jacket fatigue. During dynamic movement, the bend radius must not fall below 7.5 × D, while fixed routing permits a minimum bend radius of 5 × D. A maximum torsional allowance of ±30°/m lets the cable follow the movement of rotary tables or robotic wrists without excessive strain. Leakage capacitance is limited to 0.4 nF/m, minimizing reactive current during motor operation. The polyurethane jacket provides abrasion resistance as the cable travels repeatedly through guides and carrier links. Proper bend-radius and torsion control helps prevent excessive mechanical stress on the conductors and insulation during continuous movement.
