Product Description:
The RKG0031 is an encoder feedback cable manufactured by Bosch Rexroth Indramat for the RKG Encoder Cables series. It transmits position data and auxiliary sensor power between servo motors and drive controllers, supporting closed-loop motion control in industrial automation cells. The assembly ships with INS0451/C01 on the motor end and INS0761/L01 on the cabinet end, so it mates directly with standard Indramat encoder and controller connectors. This layout allows the cable to carry feedback signals and support lines in one assembly, which helps keep routing compact around moving axes.
The cable is rated for 5 million bending cycles, indicating how many flex motions it can withstand before conductor fatigue becomes critical in continuously moving applications. It is produced from bulk cable type INK0280, a cable designation used for the insulation wall thickness, shielding, and conductor strand count needed for noise-resistant signal transmission. The conductor set follows a mixed-gauge layout of 3x0.25 + 3x(2x0.25)StC + 2x1.0 mm². This arrangement separates feedback pairs from power pairs while maintaining a compact outer profile. Each 0.25 mm² signal core exhibits a loop resistance of 83.0 ohm/km, which helps limit voltage drop over longer runs and supports accurate interpretation of low-level differential signals. The control cores can carry up to 300 V, providing margin for typical encoder supply and auxiliary status lines.
Continuous movement is supported by a dynamic flex limit of 7.5 x D, while fixed routing requires only 5 x D, so separate bend allowances can be used for travel and stationary sections. The outer jacket is colored RAL 2003 (orange) for quick visual identification and is molded from PUR, which resists oil, abrasion, and welding sparks. The construction is halogen-free to reduce toxic emissions during a fire. It is also suitable for drag-chain use, where stable flexibility and low jacket wear are important during repeated motion.
