Product Description:

The RL2-066KBB is a motor power cable assembled by Bosch Rexroth Indramat for the RL2 Motor Power Cables series. It links second-generation synchronous motors to Rexroth drive controllers, transferring three-phase power and auxiliary signals in automated equipment such as packaging lines and transfer modules. The cable maintains electrical integrity while withstanding repeated flexing inside energy chains, making it suitable for industrial motion systems that use moving motor connections.

The cable is rated for 5,000,000 bending cycles, supporting continuous motion in cable carriers used on pick-and-place equipment and gantry axes. A conductor cross section of 25.0 mm² provides low resistance for high peak currents. The threaded motor connector uses the large M58 size with A/B keying to prevent mismating during installation. The power cores have a rated voltage of 600/1000 V, making them suitable for common 400 V AC drive systems. The maximum conductor temperature is 90 °C when the cable is installed in fixed routing. Stationary routing permits a minimum bend radius of 5 × D without damaging the outer jacket or placing excessive stress on the internal conductors.

The signal pair within the wiring harness has a voltage rating of 450/750 V, separating the auxiliary circuits from the higher-energy power cores. The cable can operate at temperatures as low as -30 °C, allowing machinery to start in unheated facilities. During repeated movement, the cable must maintain a minimum dynamic bend radius of 7.5 × D to limit conductor fatigue. A wear-resistant PUR outer jacket in RAL 2003 orange protects the conductor bundle from oil, abrasion, and weld spatter while improving visibility inside machinery. In moving applications, the conductor temperature must not exceed 80 °C, which helps preserve the insulation and jacket during continuous flexing. Proper routing within an energy chain also prevents twisting and localized pressure that could shorten the cable’s service life.
