Product Description:

The RKG0019 is an encoder cable produced by Bosch Rexroth Indramat within the RKG Encoder Cables series. It is designed to relay incremental or absolute position signals between drive electronics and motor feedback devices in industrial automation cells. By combining pre-assembled connectors with a flexible, shielded jacket, the cable maintains signal integrity in moving cable tracks and reduces wiring time on packaging machines, pick-and-place arms, and other systems that experience continuous motion.

A bending life of 2,000,000 strokes means the conductor bundle can flex through two million drag-chain cycles before mechanical fatigue becomes critical. The cable core follows the Bosch Rexroth INK family, identified as bulk type INK0720, so its dielectric layout and impedance match encoder transceivers. Inside the assembly, control pairs are grouped in a 3x(2x0.25) StC configuration, supplying twisted-pair symmetry that minimizes crosstalk. When installed in dynamic carriers, the minimum bending radius is 10xD, allowing tight routing without compressive damage. A vivid Orange (RAL 2003) polyurethane jacket and a total braided shield combine to offer abrasion resistance and electromagnetic suppression while keeping overall diameter compact.

The molded plug on the motor side is coded as INS0451, while the drive-controller end terminates in an INS0488 mating connector, ensuring keyed engagement and strain relief. For stationary runs, a static bending radius of 6xD is allowed, and the PUR outer jacket resists cutting fluids without halogen compounds. Conductors may reach 80 °C during peak current flow, so cabinet cooling must keep ambient rise inside limits. At only 0.13 kg/m, the assembly adds little mass to moving axes, and the separate power supply pair carries 2x1.0 mm² copper so auxiliary sensor power is delivered without voltage drop.
