RKG0041 by Bosch Rexroth Indramat

The RKG0041 encoder cable is produced by Bosch Rexroth Indramat and belongs to the RKG Encoder Cables series. It is supplied as a finished assembly for connecting axis-mounted encoders to compatible Rexroth drive controllers in industrial automation systems. By preserving signal quality across the full cable length, it supports accurate transfer of position data for closed-loop motion control. This makes it suitable for packaging equipment, pick-and-place gantries, and other machines that depend on stable encoder feedback during repeated movement.

The cable has a ready-made construction, so its terminations are already crimped and molded and no field wiring is required. It carries the product level Basic, indicating a standard shielding and jacket arrangement for general-purpose routing in energy chains. On the feedback side, the assembly uses connector INS0753/C01, while the drive side uses connector RGS0001/K01. It is designated as an encoder cable, which means the conductor layout supports differential feedback signals, and the keyed connector bodies help prevent mismating during installation. During motion, the cable can flex repeatedly through moving cable carriers without placing excessive strain on the conductors when routing follows the required bend limits.

At rest, the cable allows a bending radius of 4 × D, which helps with compact routing inside cabinets and machine frames. The jacket and insulation are rated for 5,000,000 flex cycles, supporting long service life in applications with constant travel. Its operating temperature range extends from -20 °C to 80 °C, while storage is permitted down to -40 °C. These limits support use in factory environments where cables are exposed to repeated motion, changing ambient conditions, and extended idle periods before installation.
