Product Description:
The RKL4344 is a motor-power cable produced by Bosch Rexroth Indramat for its RKL Motor Power Cables series. Designed as the energy link between Indramat drives and synchronous motors, the assembly combines power conductors and paired control cores within a flexible yet abrasion-resistant PUR jacket to support dynamic routing in automated handling systems and transfer lines.
The cable has a life rating of 5 million flex cycles when routed within its mechanical limits. For permanently installed runs the minimum bend is 5 x D, while moving cable chains require a larger radius of 7.5 x D; both limits help prevent conductor fatigue. A bulk designation of INK0606 identifies the core insulation and screen structure used across the series. Overall diameter is 25.5 mm, giving panel builders a clear reference for gland and chain sizing. A matte, adhesion-free PUR sheath in RAL 2003 safeguards the bundle against oils and weld spatter without sticking to adjacent hoses during motion.
Power is carried on a 4x16 mm² bundle, and two shielded control pairs (2x(2x1.5 mm²) StC) handle temperature or brake signals. Loop resistance is limited to 1.21 Ω/km, keeping voltage drop low on long axes. Drive-end termination is supplied with an RLS0721/K16 connector, while the motor side uses an RLS1301/C16 plug, simplifying field replacement without crimp tools. Charging of the drive output stage is moderated by a line-to-shield capacitance of 1.2 nF/m, a value selected to maintain EMC compliance alongside fast-switching IGBTs.
Wake Industrial stocks this cable, can arrange same-day shipping on qualifying orders, and issues quotations that remain valid for 30 days.
