Product Description:

The RLC1-121BGB is a ready-made motor power cable manufactured by Bosch Rexroth Indramat and assigned to the RLC1 Motor Power Cables series. It routes three-phase supply conductors and protective earth in automated machinery where repeated motion requires a flexible yet robust power link. Factory-terminated ends with molded strain relief reduce wiring errors, accelerate commissioning, and help maintain electromagnetic compatibility within moving energy-chain applications.

Mechanical endurance is defined by a flex life of 5,000,000 double strokes, so the jacket material and strain relief can withstand long operating periods in cable tracks. Motion planning is aided by a minimum dynamic routing radius of 7.5xD, where D is the outer diameter, preventing conductor fatigue when machines cycle at high speed. Inside the sheath, 4 fine-strand copper cores each measure 0.75 mm²; this cross-section offers a calculated voltage drop suitable for low-power linear motors. The cable can transmit up to 10.4 A continuously without exceeding permissible temperature rise, allowing the drive to deliver nominal motor current while still meeting insulation class limits. A direct connection layout eliminates intermediate terminal blocks, thereby minimizing contact resistance and simplifying maintenance.

The cable is explicitly qualified for IndraDrive servo inverters, ensuring impedance matching and reliable fault monitoring over its full length. On the motor side it connects to ML3 linear modules through an M23 (double clamping) plug that grips both shield braid and jacket against vibration. When laid permanently, the bend limit relaxes to 5xD, so tight cabinet or gantry layouts are possible without overstressing the insulation system. Supplied in the power-cable variant of the RLC1 design, the assembly delivers a basic yet dependable link for packaging lines, pick-and-place axes, and other cyclic motion stations.
