Product Description:

The RLC1-127ECB is a motor power cable produced by Bosch Rexroth Indramat within the RLC1 Motor Power Cables series. It serves as the dedicated link between a drive controller and its associated servo or spindle motor, carrying phase current, protective grounding, and optional sensor conductors through a single jacketed line. The cable is intended for continuously moving machine sections such as gantry axes, pick-and-place arms, and linear transfer stations where repeatable energy delivery and mechanical longevity are required.

The conductor pack has a cross-sectional area of 2.5 mm², so the voltage drop remains low over typical machine lengths while allowing a compact outer diameter. When routed through drag chains, the cable can flex to a dynamic bend radius of 7.5 × D; this flexibility limits copper strain during high-speed reciprocation. The cable can withstand 5,000,000 cycles of reciprocal motion, making it suitable for continuously operating production equipment. At the motor end, an M23 power connector provides a keyed, shielded interface that locks with a single quarter-turn, helping prevent wiring errors during installation. The jacket compounds tolerate conductor temperatures up to 80 °C, allowing the assembly to operate near warm servo housings or inside ventilated enclosures without accelerated aging.

The cable remains pliable down to -30 °C, so machine starts in unheated facilities do not cause the sheath to crack. A direct motor-to-drive connection eliminates the need for intermediate terminal boxes, reducing contact resistance and assembly time. During fixed installation or in cabinet slack loops, the sheath can rest at a static bend radius of 5 × D without damaging the conductors. The cable may be stored at temperatures as high as 80 °C without loss of dielectric strength or jacket integrity.
