RKG4201T007 by Bosch Rexroth Indramat

The RKG4201T007 is an encoder feedback cable produced by Bosch Rexroth Indramat within the RKG Encoder Cables series. The assembly links position transducers to drive controllers, carrying incremental or absolute signals while withstanding constant motion in handling systems, pick-and-place modules, and gantry axes. Its geometry, shielding, and molded backshells allow the cable to be routed through standard drag chains without impairing signal fidelity or exceeding permitted mechanical loads in automated equipment.

This model is rated for 5,000,000 bending cycles, a figure that indicates how many flexing actions the conductors and jacket can tolerate before fatigue becomes critical. The outer jacket is made of PUR, giving the sheath resistance to cutting oils and providing low-friction sliding against cable guides. One end is fitted with a keyed RGS1001 plug, and the opposite end terminates in a matching RGS1002 receptacle; these coded connectors prevent polarity errors during connection and maintain 360-degree shielding continuity. Internal control pairs use a cross-section of 0.25 mm², balancing conductor resistance with the need for compact bending behavior. While the cable is in motion, it must not be curved tighter than a radius of 7.5xD. This dynamic limit reduces strain on the copper strands and the drain braid.

Once routed and locked in place, the minimum stationary curve tightens to 5xD, allowing closer wiring inside cabinets without risking kinks. The jacket color follows RAL 2003, giving the orange sheath high visibility and matching Rexroth wiring color codes. Suitability for drag chain use confirms that the layered insulation, filler, and braid can endure continuous reciprocal travel, vibration, and incidental abrasion typical in energy-chain applications.
