RKL0052 Bosch Rexroth Indramat

Product Description:

The RKL0052 cable is supplied by Bosch Rexroth Indramat as part of the RKL Motor Power Cables series. It is a preassembled motor-power interconnect that carries three-phase drive energy and auxiliary sensor lines between the servo controller and the matched Rexroth motor. Within automated machinery this cable completes the power circuit, allowing the drive to energize and monitor the motor without separate field wiring. Its molded connectors speed installation and maintain the electromagnetic compatibility required in dynamic industrial environments.

The main circuit inside the RKL0052 contains 3 power conductors, each sized at 2.5 mm², providing an adequate cross-section for typical low-to-medium power IndraDrive axes. Parallel to the power cores are 4 auxiliary conductors for brake release or thermal sensing, and these support feedback currents through a dedicated 1.0 mm² copper section. Factory-terminated plugs simplify cabinet layout: the controller end uses an RLS0749/K03 coupling, while the motor side is finished with an RLS1201/C03 plug. For inventory and replacement tracking the bulk cable is identified by code INK0602, ensuring that the sheath, shielding and conductor lay match Rexroth electrical and mechanical standards.

Continuous motion duties are addressed by a flex-rated design verified for 5,000,000 bending cycles. In dynamic drag-chain routes the cable follows a minimum bend of 7.5 × D, whereas fixed routing may employ a tighter 5 × D radius without premature jacket fatigue. Service temperatures during operation span from -30 °C up to 80 °C; the same limits apply during storage, so no special handling is needed between commissioning and installation. These mechanical and thermal capabilities align the RKL0052 with high-speed pick-and-place gantries and multi-axis transfer lines that impose frequent flex and variable ambient conditions.
