Product Description:

The RL2-104EBB cable is produced by Bosch Rexroth Indramat as part of the RL2 Motor Power Cables series. It is a motor-side power lead designed for the second-generation Rexroth servo motors, providing phase conductors and auxiliary cores in one jacket so installers can deliver power and signal return through a single routed assembly in industrial automation cells.

This basic-design cable contains a conductor set identified as 4x L + 4x 0.75 mm², and each power core features a cross-section of 2.5 mm² to carry motor currents while limiting voltage drop over distance. Insulation resistance at 20 °C is at least ≥ 20 MΩ/km, supporting insulation monitoring routines used in modern drive systems. A robust PUR outer jacket enhances abrasion and coolant resistance, making the product suitable for drag-chain layouts. The power cores are rated to 600/1000 V, whereas the smaller control pairs are specified for 450/750 V, enabling mixed-signal service in compact harnesses. All materials comply with the temperature envelope needed for +80 °C continuous service and integrate into the Rexroth Cable product group without additional termination changes.

The copper strands can operate up to +90 °C when permanently installed and up to +80 °C during flexible motion, providing thermal headroom for peak current events. Dynamic routing inside cable carriers requires a minimum bend radius of 7.5 × D, while static fastening may tighten bends down to 5 × D. Cold-store or outdoor machinery can deploy the lead to environments as low as -30 °C when fixed and –20 °C during motion, and service temperatures remain valid up to +60 °C under flexible duty. These limits, combined with 2nd-generation motor compatibility, ensure reliable torque delivery across diverse installation styles.

Wake Industrial offers a 1-year warranty on each RL2-series cable. Same-day shipping is available for qualifying orders. Written quotations remain valid for 30 days to simplify budgeting.
