Product Description:
The RKG0040 cable assembly is produced by Bosch Rexroth Indramat and belongs to the RKG Encoder Cables series. It links linear or rotary feedback devices to Rexroth drive controllers, transmitting differential encoder signals and auxiliary power within automated machinery. By combining signal pairs and supply conductors inside a single routed lead, the assembly simplifies cabinet wiring and supports continuous motion applications that rely on precise position feedback for closed-loop motor control.
The bulk conductor employed is INK0448, a construction that integrates four twisted signal pairs plus two power cores. Overall outside diameter is 8.8 mm, so carriers and glands must accommodate that size. A polyurethane sheath made of PUR resists oil, weld spatter, and abrasion encountered on moving axes. During dynamic operation the cable tolerates up to 5,000,000 bending cycles, provided the flexible routing radius is kept to 7.5 × D; tighter loops accelerate fatigue and signal degradation. These ratings mean the lead can ride in energy-chain tracks beside servo power conductors without premature jacket cracking or pair untwist.
Interface hardware is fixed at each end: the encoder side carries an INS0753/C01 plug, while the controller side terminates in an INS0769/L01 connector, eliminating field crimping and ensuring shield continuity. Internally the arrangement of 4×2×0.25 mm² + 2×0.5 mm² conductors keeps impedance balanced for high-speed incremental channels and reserves separate supply lines for encoder electronics. The orange outer jacket specified as Orange (RAL 2003) provides quick visual identification in crowded drag chains. Because the fixed installation radius is 5 × D, the cable can transition from cabinet to moving carrier without exceeding strain limits, and the 2 × 0.5 mm² supply wires deliver stable sensor voltage over typical lengths found on modular production lines.
