Product Description:

The RKG4201T010 is an encoder feedback cable produced by Bosch Rexroth Indramat within the RKG Encoder Cables series. It carries differential position signals and auxiliary control lines between a motor-mounted measuring system and the associated drive controller in automated machinery. By operating within the required electrical and mechanical limits, the cable helps preserve signal integrity on moving axes and withstands continual motion inside energy-chain assemblies. This makes it suitable for applications where stable feedback transmission is needed during repeated machine travel.

The cable is rated for 5,000,000 flex cycles, indicating how many repeated bends it can endure without conductor fatigue when installed in a continuously moving carrier. An outer diameter of 8.8 mm sets the clamping range for strain-relief glands and guides, while each control core has a cross-section of 0.25 mm² to support encoder-level currents without adding unnecessary bulk. For drag-chain layouts, the minimum loop is 7.5xD, while at rest the cable may be laid with a tighter 5xD bend inside cabinets. A chemically resistant PUR jacket shields the cores from oils and abrasion, and the assembly remains functional from −40 °C to 80 °C in typical operating conditions.

Signal consistency is supported by the low-capacitance geometry of the INK0448 bulk cable used for this model. Factory terminations use an angled RGS1001 plug on the encoder side and a straight RGS1002 plug on the controller side, which helps keep the connection layout clear and reduces the chance of mismatched pin assignments. The orange sheath improves visibility in cable tracks and other dense routing areas where multiple moving leads are installed together. The cable is intended for drag-chain use, and the same temperature range also applies during storage, so spare assemblies can be kept in unheated warehouse areas without material degradation.
