RKL0102 by Bosch Rexroth Indramat

The RKL0102 motor power cable is produced by Bosch Rexroth Indramat within the RKL Motor Power Cables series. Designed for fixed installation between an IndraDrive servo amplifier and a synchronous motor, the cable delivers phase power and protective earth in automated machinery that operates with repetitive motion. Its molded connectors and shielded conductors support straightforward installation and maintain the electromagnetic compatibility required for dynamic drive axes. By packaging the conductors in a continuous shield, it also limits radiated emissions that could interfere with adjacent sensors.

The cable is specified for 5,000,000 flex cycles in a drag-chain environment, indicating the jacket and conductor insulation endure frequent reciprocating motion without cracking. It tolerates combined bending and torsion of ±180°/30 cm, so a half-turn twist over a 300 mm segment can be applied at each stroke. Dynamic travel loops require a minimum curve of 7.5 x D, where D is the outer diameter, while static routing may tighten to 5 x D when the machine is idle. Because it is delivered as a Ready-Made assembly, no field crimping or potting is needed, and the over-molded construction helps maintain ingress protection along the full stroke.

At each end, the RKL0102 carries coded circular plugs; the motor side uses RLS1108 and the drive side terminates with RLS0746, ensuring polarity consistency across the series. Continuous service is allowed from -30 °C up to 80 °C, so the same harness can operate in refrigerated zones or near enclosure heaters. The identical storage range helps prevent insulation embrittlement during warehousing. Classified as a power cable variant, the conductors carry three motor phases plus protective earth, and the braided copper shield maintains low-impedance grounding for high-frequency switching edges.
