Product Description:
The RKG0057 encoder cable assembly is produced by Bosch Rexroth Indramat as part of the RKG Encoder Cables series. The cable links motor-mounted encoder feedback devices to drive controllers. In closed-loop industrial automation, this pre-terminated lead provides reliable signal integrity and mechanical reliability between moving axes and stationary control cabinets. The RKG0057 designation identifies a specific length and connector configuration within the family.
The conductors follow the [4×0.5 mm² + 5×(2×0.14) StC]C layout, giving separate twisted pairs for incremental channels and auxiliary functions. The cable outer sheath measures 10.0 mm in diameter and is colored RAL2003 orange for quick field identification. For dynamic routing, it tolerates continuous flexing down to a bend radius of 7.5xD, while fixed installations require only 4xD. Combined with drag-chain suitability, this geometry survives up to 5,000,000 bending cycles at axial accelerations of 50 m/s² without conductor fatigue. The halogen-free design limits corrosive gas release during a fire.
Thermal performance is defined by a maximum conductor temperature of 80 °C, allowing operation near motor housings without premature insulation aging. The outer jacket is manufactured from PUR, providing abrasion resistance when the cable glides in energy chains. Factory-molded circular connectors, type RGS1711 on the encoder side and RGS1712 at the drive interface, eliminate wiring errors and assure EMC shielding continuity. The assembly originates from bulk cable REG0011, so electrical parameters such as impedance and capacitance match the drive family’s feedback requirements. These features make the RKG0057 suitable for high-duty pick-and-place modules and gantry axes that demand precise feedback under continuous motion.
