Product Description:
The RKL0012 motor power cable is produced by Bosch Rexroth Indramat for the RKL Motor Power Cables series. It links an IndraDrive controller to a synchronous servo motor and carries phase power together with auxiliary sensor or brake lines, allowing coordinated motion in automated machinery and material-handling stations. The cable is intended for installations that require dynamic routing through cable tracks, providing electrical continuity between the drive cabinet and moving axis while resisting mechanical fatigue.
The cable contains power cores with a cross-sectional area of 4.0 mm², allowing them to carry standard servo currents with limited voltage drop over typical axis lengths. Additional auxiliary bundles are arranged as 2 × 1.0 mm² plus 2 × 1.5 mm² to carry encoder reference or holding-brake feeds without interference. A durable PUR outer sheath protects the conductor bundle from oil and coolants. The circular profile has an overall diameter of 17.0 mm, allowing the cable to fit common drag-chain separators. Stationary sections require a minimum bend radius of 5 × D, while moving sections require a minimum bend radius of 7.5 × D to prevent conductor corkscrewing or shield damage. These bend requirements help preserve electrical continuity when the cable is routed between fixed and moving machine sections.
The cable is rated for up to 5,000,000 bending cycles in drag-chain applications without an insulation breach. A keyed RLS0721 connector mates with the controller, while an RLS1201 connector locks onto the motor housing to maintain secure electrical connections during repeated movement. The sheath has a highly visible RAL 2003 orange finish, making the cable easier to identify along machine frames. Its drag-chain compatibility allows routing through long-travel carriers when the auxiliary conductor pairings and braided shield remain within their permitted load limits. The jacket also protects the internal conductors from routine exposure to industrial fluids while maintaining the flexibility needed for moving-axis applications.
