RL2-003CBB by Bosch Rexroth Indramat

The RL2-003CBB cable is produced by Bosch Rexroth Indramat and belongs to the RL2 Motor Power Cables series. It is a flexible motor power cable intended for connecting second-generation IndraDrive servo motors to their drive amplifiers in industrial automation lines. By carrying phase and protective conductor current while tolerating dynamic motion inside cable tracks, the assembly supports consistent motor power delivery in packaging, handling, and machining cells. It is designed for continuous drag-chain operation and supports rapid axis movements without premature insulation wear.

The cable has a bend endurance of 5,000,000 cycles, which indicates long service life in energy-chain applications. Its conductor arrangement is 4x L + 4x 0.75 mm², pairing four power conductors with four smaller conductors for functions such as brake or temperature signals. Each power core has a cross-section of 1.0 mm², which suits low-to-medium torque axes. Connection at the motor end is made through a D (M17) circular plug for quick coupling to sealed motor receptacles. Mechanical protection is provided by a PUR (Orange RAL 2003) outer jacket that resists oil and abrasion while remaining flexible. During motion, the cable must maintain a dynamic bend radius of 7.5 × D to help prevent kinking.

The cable uses a Basic design that omits shielding and is intended for short motor power leads. It is halogen-free, which helps limit toxic gas release during a fire, and it is also silicone-free, which helps prevent surface contamination in paint or food-processing areas. The materials are also CFC-free. The assembly is matched to the second motor generation so the pinout and insulation class align with newer Rexroth stators. It is part of the Rexroth Cable product group and fits standard routing accessories.
