Product Description:

The RLC1-126ECB is a motor power cable manufactured by Bosch Rexroth Indramat within the RLC1 Motor Power Cables series. Intended for connection between IndraDrive controllers and ML-class motors, the cable transmits three-phase power while maintaining mechanical flexibility for continuously moving axes in automated machinery and robotics.

This model is rated for 5,000,000 bending cycles, indicating the number of reciprocating motions it can endure before conductor fatigue becomes critical. A conductor cross-section of 2.5 mm² balances current-carrying capacity with manageable outer diameter, making routing through energy chains straightforward. During dynamic motion the cable must follow a minimum bend of 7.5xD, so installers calculate the smallest loop radius as 7.5 times the outer diameter to avoid internal strand damage. Power reaches the motor through a shielded M23 (Double Clamping) connector that provides strain relief and reliable earth continuity. On the cabinet side, the assembly mates directly with IndraDrive amplifiers, and this compatibility is highlighted by the designation IndraDrive.

When the machine is idle the cable may rest in tighter loops down to a static radius of 5xD without compromising insulation integrity. Mechanical keying and pin assignments match the ML3 motor family, simplifying field replacement and preventing wiring errors. The overall construction follows the series’ Basic cable design, which omits extra coolant channels and thus reduces weight while retaining the necessary copper screening for EMC compliance. Drive connection is direct, eliminating intermediate terminal boxes and shortening installation time.

Wake Industrial keeps this cable in stock, offers same-day shipping when required, and supplies a 1-year warranty on every purchase; detailed quotations remain valid for 30 days to support planned maintenance budgets.
