Product Description:
The RL2-166MBB is a motor power cable produced by Bosch Rexroth Indramat for the RL2 Motor Power Cables series. It is intended for routing power between Rexroth second-generation servo motors and their drive controllers in automated cells, where continuous flexing and torsion are expected during axis motion.
The mechanical endurance of the cable is rated for 5,000,000 bending cycles, allowing installation in energy-chain or robotic applications. A copper conductor area of AWG1/0 cross-section supports high current flow at a maximum operating potential of 600/1000 V on the power cores. Dynamic handling is aided by a torsional limit of ±30 °/m torsion and a minimum dynamic bend radius of 7.5 × D dynamic bend radius. The design is classified as Basic, and the four power lines are paired with four 0.75 mm² signal leads to separate feedback circuits from motor phases. Polypropylene insulation surrounds each conductor, while the PUR outer sheath carries the orange RAL 2003 color for quick identification. Rated signal voltage is 450/750 V, and static routing may follow a 4 × D minimum bend guideline.
The internal core arrangement is described as 4x L + 4x 0.75 mm², terminated through a factory-molded M50 connector that allows direct connection to the motor without junction boxes. A tough PUR jacket resists oils and weld spatter, maintaining at least 20 MΩ/km insulation resistance at 20 °C to limit leakage currents. Connection to the cabinet side is direct, which shortens installation time and reduces contact points. The product belongs to the Rexroth Cable group and may operate under combined bending and torsion while remaining within its 2nd motor generation dimensional standards.
