Product Description:

The RKL4589 is a motor power cable manufactured by Bosch Rexroth Indramat for the RKL Motor Power Cables series. It delivers three-phase power and auxiliary control signals to servomotors in automated machinery while withstanding continuous flexing inside drag-chain assemblies. This type of cable is commonly used where a drive cabinet must route power and auxiliary lines through moving carriers to a motor on a reciprocating axis. The cable uses shielding and durable jacket materials to reduce electrical noise and mechanical wear in high-cycle production environments where uninterrupted motion control is required.

The cable is rated for a service life of 5,000,000 bending cycles in drag-chain operation, making it suitable for repeated movement over long operating periods. A minimum bend radius of 5 × D applies to fixed routing, while a larger 7.5 × D radius is required during motion to reduce conductor stress. It supports system accelerations up to 10 m/s² and travel velocities up to 5 m/s. The adhesion-free matte jacket helps reduce abrasion against guide channels, and the cable is approved for drag-chain use in dynamic energy-supply systems. These motion limits are useful in gantries, transfer units, and other automated handling equipment that cycle continuously throughout the day.

The control cores are insulated for up to 300 V, and the power conductors can handle up to 600 V AC in the same cable run. An outer jacket in RAL 2003 makes the cable easy to identify, while the PUR compound resists coolants and cutting oils commonly found around machine tools. The cable is halogen-free to reduce toxic emissions during a fire. Braided and foil shielding helps limit electromagnetic interference with nearby feedback lines and sensors. That combination supports cleaner signal transmission when motor power wiring is installed alongside encoder or control wiring in compact machine layouts.
