Product Description:
The RL2-105FBB is a motor power cable produced by Bosch Rexroth Indramat and supplied within the RL2 Motor Power Cables series. It links power inverters to second-generation synchronous or asynchronous motors through the T (M32) terminal box interface, ensuring a routed connection that meets the mechanical motion demands of automated machinery.
This cable is rated for 5,000,000 bending cycles, a figure that indicates its durability inside energy-chain or gantry applications where continuous flexing occurs. A PUR (orange RAL 2003) outer jacket resists oil, abrasion, and welding spatter while providing high visibility for safety checks. Internally, the conductor layout follows the 4x L + 4x 0.75 mm² schema; four power cores with 4.0 mm² cross section deliver motor current, and four 0.75 mm² cores support thermal sensors or brakes. For fixed routing, the copper may reach 90 °C without degradation, whereas the limit under continuous motion is 80 °C. The design is classified as Basic, reflecting the standard insulation wall thickness defined for the Rexroth Cable product group. Mechanical twist tolerance extends to ±30°/m, allowing installation in rotating axes such as robotic wrists without conductor fatigue.
The dynamic bending radius requirement is 7.5 × D, and the static radius tightens to 5 × D, so cabinet raceways can be compact while still respecting strain relief guidelines. Power conductors carry up to 600/1000 V, and the control pair is insulated for 450/750 V, separating drive output from low-level feedback circuits. Continuous service is permissible between -30 to +80 °C when the cable is fixed, and from –20 to +60 °C during flexing, enabling deployment in chilled storage, foundry gantries, or outdoor transfer lines. All parameters correspond to the 2nd motor generation, so connector pin-outs, shielding, and geometry align with current Rexroth drive standards.
