Product Description:
The RKL4341 motor power cable is produced by Bosch Rexroth Indramat within the RKL Motor Power Cables series. It carries three-phase drive power and protective earth between an IndraDrive inverter and a synchronous servo motor, making it a dedicated component for automated axes that require high current and continuous flexing. Preassembled connectors and optimized jacket compounds simplify installation and help keep electromagnetic emissions within permissible industrial limits.
The cable includes three finely stranded copper power cores with a cross-sectional area of 25.0 mm² and a control core with a cross-sectional area of 1.5 mm² for auxiliary functions such as brake actuation. These conductors are crimped to an angled RLS1301 plug on the motor side and a straight RLS1302 plug on the cabinet side. Both interfaces use the compact C25 housing, which locks with a quarter turn. The cable is rated for 5,000,000 flex cycles in energy chains, allowing it to follow fast linear gantries during repetitive motion. Its high strand count, tinned surfaces, and tight-pitch shielding minimize resistive losses and reduce electrical noise near the high-power phase conductors.
The underlying bulk cable, referenced as INK0607, has a polyurethane sheath that withstands coolants and lubricants while remaining flexible. For moving runs, the cable must maintain a minimum bend radius of 7.5 × D, while static cabinet routing permits a minimum bend radius of 5 × D without stressing the insulation. The operating temperature range extends from -30 °C to 80 °C, permitting year-round service in unheated plants and operation in machines with elevated enclosure temperatures. A striped green-and-yellow protective-earth conductor provides standardized grounding. Molded strain relief at each connector prevents the jacket from creeping, helping the clamped contacts maintain consistent crimp resistance throughout the cable’s range of motion.
