RL2-010CBT by Bosch Rexroth Indramat

The RL2-010CBT is a motor power cable produced by Bosch Rexroth Indramat for the RL2 Motor Power Cables series. It connects drive controllers to second-generation servo motors in automated machinery and carries both power and feedback conductors in one molded assembly. This arrangement helps reduce cable bulk on moving axes where routing space is limited. It is suited for industrial installations that require dependable electrical continuity during repeated machine motion.

The cable uses a Torsion design, so the conductors can tolerate repeated twisting around the cable axis during operation. A compact M17 connector mates directly with the corresponding motor receptacle and keeps the connection compact. Each copper core has a cross-section of 1.0 mm², which supports current flow appropriate for servo applications. The outer jacket is made of PUR (Orange RAL 2003), providing resistance to abrasion and common cutting oils while remaining flexible. The power conductors have a nominal insulation rating of 600/1000 V, making the cable suitable for common DC-link voltages used with synchronous drive systems.

Signal pairs inside the same sheath carry encoder data and have a 450/750 V insulation rating, which helps maintain separation between power and feedback circuits. In fixed installation, the copper strands may reach 90 °C, while continuous motion limits the conductor temperature to 80 °C to reduce thermal aging. The minimum bend radius is 5 × D for static laying and 7.5 × D for dynamic routing, helping protect the insulation during installation and movement. Insulation resistance is rated at 20 M?/km at 20 °C, which supports stable signal transmission over the cable length. The internal conductor arrangement matches second-generation motor connector pinouts, so the cable can be connected to compatible Rexroth drive systems without additional adapters.
