Product Description:
The RL2-046DBB is a motor power cable produced by Bosch Rexroth Indramat within the RL2 Motor Power Cables series. It is used in industrial automation to route drive output to motors, supplying both power conductors and low-level signals in a single assembly so that second-generation actuators can be wired quickly on the machine frame.
This Rexroth Cable is built in a Basic design with a cable construction of 4 x 1.5 mm² for the load lines and 4 x 0.75 mm² for auxiliary cores; the arrangement matches the cable type described as 4x L + 4x 0.75 mm². Each load core has a nominal cross-section of 1.5 mm², giving the assembly a current carrying capacity of 15.6 A under continuous duty. The orange jacket in RAL 2003 is extruded from PUR, a material that resists cutting fluids and repeated flexing while keeping the outer diameter to 12.2 mm. Conductive screens and geometry limit capacitive coupling so that leakage capacitance stays at 0.4 nF/m, helping drives meet EMC targets on long runs. The power pair is insulated for up to 600/1000 V, allowing this cable to serve drives that operate on common low-voltage and medium-voltage DC bus architectures without additional derating.
Thermal limits are defined at a fixed-installation conductor temperature of 90 °C and a flexible-routing limit of 80 °C, so cabinet and drag-chain sections can be designed with clear allowances for ambient rise. The signal cores carry encoder or brake circuits and are rated up to 450/750 V, preventing insulation breakdown when feedback devices share the same cable path as the power lines. An M40 threaded connector terminates the motor end, matching the interface on second-generation Rexroth servo motors and reducing assembly time because no field crimping is required.
