Product Description:

The RL2-542DBB motor power cable is produced by Bosch Rexroth Indramat and belongs to the RL2 Motor Power Cables series in the Rexroth Cable product group. It is intended for wiring second-generation servo motors to their matched drives, supplying motor power along with low-level sensor connections in the dynamic drag-chain routes used in automated machinery. Its cable design combines power and signal conductors, allowing one assembly to be routed instead of separate power and sensor lines.

The cable supports up to 5,000,000 flex cycles and permits continuous movement at a minimum dynamic bend radius of 7.5 × D. When the cable is installed permanently, the minimum static bend radius is 5 × D. Internally, the cable contains four 1.5 mm² power conductors and four 0.75 mm² auxiliary conductors, providing separate paths for motor power and auxiliary signals. The copper conductors support continuous operation at temperatures up to 90 °C, allowing use at elevated cabinet temperatures before derating becomes necessary. This internal arrangement simplifies termination and helps maintain consistent electrical performance along the entire cable length.

The insulation system provides a minimum resistance of 20 MΩ/km, helping limit leakage current over long cable runs. The conductors are covered by a PUR outer jacket in RAL 2003 orange that resists cutting oils and abrasion. The power conductors have a working voltage rating of 600/1000 V, while the individual signal conductors can tolerate up to 450/750 V, allowing the connections to share the same cable tray. Service temperatures range from -30 °C to +80 °C in fixed installations and from -20 °C to +60 °C during continuous movement. The PUR jacket remains flexible throughout this temperature range, supporting repeated motion in cold-storage conveyors and warm production cells without requiring a separate protective sheath.
