Product Description:
The RL2-522EBB cable is a motor power lead manufactured by Bosch Rexroth Indramat within the RL2 Motor Power Cables series. It belongs to the Rexroth Cable product group and links drive controllers to the 2nd motor generation used in automated handling, packaging, and machining cells. By combining power and signal pairs in a single assembly, the cable reduces panel space and installation time while maintaining consistent electrical characteristics along moving machine axes.
The basic construction employs a PUR (Orange RAL 2003) outer jacket that resists oils and abrasion encountered in drag-chain operation. Four load conductors share a cross-section of 2.5 mm², and the bundle is supplemented by four 0.75 mm² signal wires arranged as 4x L + 4x 0.75 mm². Repeated motion is supported by a dynamic bending radius of 7.5xD, allowing tight loops without conductor fatigue. Endurance is further demonstrated by a rating of 5,000,000 bending cycles, making the cable suitable for high-duty robotic wrists and linear slides. The design remains flexible from –30 °C up to the application-specific thermal limits of its conductors.
When routing in static trays, a minimum bend of 5xD is sufficient, and reliable operation is maintained down to -30 °C ambient as well as up to 80 °C in the machine envelope. Fixed routing can tolerate conductor temperatures reaching 90 °C, permitting higher continuous currents under cabinet ventilation. Power cores are insulated for a nominal 600/1000 V, while the separate signal elements carry control feedback at 450/750 V. A keyed M23 (Plug U) connector terminates the motor end, ensuring quick exchange without rewiring and preserving shielding continuity across the drive system.
