Product Description:
The RKL4349 is a motor power cable produced by Bosch Rexroth Indramat within the RKL Motor Power Cables series. Serving as the power link between a Rexroth drive controller and its matched servomotor, the cable carries three-phase supply conductors along with paired signal cores for auxiliary functions in industrial automation equipment. By embedding these elements in one shielded bundle, it streamlines installation and supports coordinated motion on assembly lines, packaging cells, and robotic axes.
In dynamic applications the cable endures 5,000,000 flex cycles, so repeated motion in carriers does not weaken the conductors. A minimum bend radius of 7.5xD during movement and 5xD when fixed prevents jacket cracking. The layered design 4x16 mm² + 2x(2x1.5 mm²)StC groups power and twisted control pairs under one braid, while the overall jacket measures 25.5 mm in diameter. It is suitable for drag-chain installation and uses halogen-free insulation to limit corrosive gas release; this geometry supports continuous guidance within energy chains on pick-and-place gantries.
Electrical performance is defined by a conductor resistance of 1.21 Ω/km, keeping voltage drop low on extended travel axes, and a mutual capacitance of 1.2 nF/m, which drives sizing of output filters in high-frequency inverters. The power cores each provide 16.0 mm² of copper for current transfer, while every paired control core is 1.5 mm², allowing temperature sensors or brakes to share the same run. Factory-moulded terminations use the RLS0724/K16 connector on the controller side and the RLS1301/C16 connector on the motor side, supplying keyed, vibration-resistant interfaces for plug-and-play assembly.
