Product Description:

The RKG0020 encoder cable is produced by Bosch Rexroth Indramat within the RKG Encoder Cables series. It links motor feedback devices to drive controllers, carrying position signals while resisting mechanical stress typical of moving axes in automated machinery. By combining robust shielding with drag-chain compatible construction, the cable preserves encoder accuracy and secures closed-loop control in packaging lines, gantry systems, and robotics. The specified RKG build combines fine-stranded cores with individual foil screens to minimize capacitance and preserve high-resolution signals over several metres.

Mechanical service life is a primary feature: the cable endures 5,000,000 bending cycles when routed in energy chains, and minimum flex radii stay within 7.5 × D to avoid conductor fatigue. On the controller side a D-Sub 15-pin plug provides quick mating to Rexroth drives, while the motor end uses a 10-pin clamp terminal for field wiring. The orange RAL 2003 sheath is formed from PUR that is adhesion-free and matt, giving abrasion resistance and easy chain travel. Overall cross-section remains compact with an outer diameter of 8.8 mm, helping dense routing inside cable trays.

Electrical characteristics complement the mechanical design. Control conductors are rated for 300 V and withstand a fixed-installation conductor temperature of 90 °C. Four shielded data channels are organized as 4x(2x0.25 mm²) twisted pairs, while two 0.5 mm² supply wires carry encoder power. A Total shield of tinned copper braid surrounds all cores, rejecting EMI that can corrupt sine-cosine or digital feedback lines. Because use in drag chains is permitted, the PUR jacket resists oil and coolant ingress during continuous motion.

Wake Industrial stocks this cable and can arrange same-day shipping when production schedules are tight. Every purchase includes a 1-year warranty covering workmanship and component integrity.
