RKG0058 by Bosch Rexroth Indramat

The RKG0058 is an encoder cable produced by Bosch Rexroth Indramat for the RKG Encoder Cables series. It links position transducers to drive controllers so feedback signals remain stable during continuous motion in automated machinery. Reliable signal transmission supports closed-loop speed and position control, and the cable serves as a passive connection between the feedback device and the drive. Because encoder channels carry low-level signals, cable stability helps the control system maintain accurate velocity and position feedback during axis reversals and long duty cycles.

The polymer jacket withstands up to 5 million bending cycles when routed through drag chains, and the cable tolerates accelerations of 10 m/s² without conductor fatigue. Inside the sheath, the core grouping of 4x0.5 + 5x(2x0.14) mm² separates power conductors from differential feedback pairs to reduce crosstalk. Visual identification in crowded cable trays is straightforward because the jacket color is RAL 2003 (orange). The jacket is molded from PUR, a material chosen for abrasion resistance and oil tolerance in industrial equipment. Signal loss is also kept low by an outer diameter of 10.0 mm, which supports consistent routing and compatibility with common encoder connector formats.

The halogen-free formulation limits corrosive gas release during fire, and the cable is approved for use in drag chains. Thermal performance remains stable from -40 to +80 °C during operation, storage, and transport. For static installation, the minimum bend radius is 5 × D, while dynamic motion requires 7.5 × D to protect the shield and conductors from deformation. The flexible construction supports repeated movement in compact machine layouts where encoder cables must travel beside motor power leads. This routing behavior suits linear axes, gantries, and other moving assemblies that cycle throughout the workday.
