Product Description:
The RKG4201 is an encoder feedback lead produced by Bosch Rexroth Indramat within the RKG Encoder Cables series. The assembly links position transducers to drive controllers, carrying differential signals and supply power so that motion control loops receive accurate rotor or axis data in industrial automation cells.
For continuous motion it endures 5,000,000 bending cycles, giving predictable service life in flexing applications. During travel, the conductor bundle can bend down to 7.5×D dynamic radius without exceeding electrical or mechanical strain, where D is the outer diameter. The outer sheath measures 8.8 mm, so the minimum loop diameter under motion is about 66 mm. Inside the cable, the twisted pair layout is 4x2x0.25 mm² + 2x0.5 mm²; this segregates encoder channels from auxiliary supply leads, controlling crosstalk. The sheath consists of PUR (adhesion-free, matte), which resists oil and abrasion while preventing tack inside cable carriers. Because the jacket is smooth and drag-optimized, the model is suitable for installation in automated drag chains that require guided, repeatable flexing paths.
Terminated on one end with RGS1001 (C01) and on the other with RGS1002 (C01), the cable mates directly with Rexroth encoders and controller receptacles, removing field-crimp steps. During installation, a 5×D static radius applies, allowing routing around cabinet corners without kinking the internal pair twists. The outer covering follows RAL 2003 (orange), providing clear visual identification of feedback lines inside enclosures. RKG4201 is manufactured from bulk cable INK0448, so replacement sections share identical impedance and shielding parameters with the pre-assembled lead. Its dedicated encoder connection function keeps signal integrity from the transducer to the drive, closing the feedback loop for precise positioning without adding separate breakout boxes.
