Product Description:

The RL2-563KBB belongs to the RL2 Motor Power Cables series manufactured by Bosch Rexroth Indramat for second-generation servo motors. As a member of the Rexroth Cable product group, this basic-design lead carries three power conductors and four auxiliary cores identified as TP1, TP2, BD+ and BD-. It supplies drive-end power and feedback signals between motor and controller while withstanding industrial environments that require continuous flexing and fixed routing.

The copper conductors have a cross section of 25.0 mm², equivalent to an American wire gauge size of 4, so the cable can deliver up to 93.9 A without overheating when installed correctly. For line supply compatibility, the power cores are rated at 600/1000 V; this voltage window matches standard inverter outputs used in Rexroth motion systems. When permanently fixed, the conductor insulation tolerates temperatures up to 90 °C, allowing cabinet-side connections near warm drive electronics. The PUR outer jacket in Orange RAL 2003 shields the bundle from oil and abrasion, and its smooth surface eases drag-chain installation.

Control pairs inside the same sheath are isolated for logic levels at 450/750 V so analogue or digital signals remain stable alongside the high-energy phases. Dynamic applications can follow a minimum bend radius of 7.5 × D, whereas static layouts may tighten to 5 × D without conductor damage. A threaded M58 connector mates directly with Rexroth motor receptacles, eliminating field crimping. The jacket material is PUR (Orange RAL 2003), chosen for flexibility down to 80 °C conductor limits during motion. Together, these parameters support rapid axis moves in second-generation motors while maintaining insulation integrity, voltage margins and mechanical life across repeated machine cycles.
