Product Description:
The RL2-025CBB is a motor power cable produced by Bosch Rexroth Indramat for the RL2 Motor Power Cables series. It belongs to the Rexroth Cable product group and uses the Basic cable design intended for moving-axis energy chains. The assembly carries power and auxiliary signals from the drive to a second-generation motor through a direct connection layout, eliminating intermediate terminals and accommodating the limited space common in automated handling and packaging cells.
The cable is rated for 5,000,000 bending cycles, allowing repetitive travel in drag chains without premature conductor fatigue during long production runs. A conductor cross-section of 1.0 mm² supports the current requirements of standard servo applications, while the power cores can carry up to 600/1000 V between the drive inverter and motor terminals. For continuous movement, the dynamic bending radius must remain at or above 7.5 × D to protect the conductor strands from excessive mechanical stress. Fixed installations use a separate minimum bending radius because the cable is not exposed to repeated flexing in a stationary routing channel. Under static mounting conditions, the copper can reach a maximum temperature of +90 °C without exceeding the insulation limit, accommodating elevated cabinet temperatures during high-duty operation.
A PUR outer jacket in Orange RAL 2003 shields the conductors against abrasion and exposure to coolants while making the cable easy to identify inside machinery. During continuous movement, the conductor temperature must remain below +80 °C to prevent thermal softening of the elastomeric insulation. Encoder or brake pairs share the same sheath but operate at a reduced voltage of 450/750 V, providing suitable insulation for auxiliary circuits alongside the higher-voltage power conductors. The static bending radius of 5 × D applies to fixed cable-tray segments and permits compact routing in crowded cabinets. The direct connection arrangement reduces the number of connection points between the drive and motor, while the shared sheath keeps power and auxiliary wiring within one flexible assembly.
