Product Description:
The RKG0018 is an encoder feedback cable assembly produced by Bosch Rexroth Indramat for the RKG Encoder Cables series. It links motor-mounted measuring systems to the controller cabinet, carrying incremental or absolute position signals while also supplying sensor power, so it is installed wherever precise closed-loop control is required in automated machinery.
Mechanical durability is defined by 5,000,000 bending cycles, allowing repeated motion in highly dynamic cable tracks. During continuous flexing the minimum loop is 7.5 x D, while fixed installation requires only a 5 × D radius, preventing conductor fatigue. The outer sheath measures 9.7 mm in diameter, giving adequate wall thickness for abrasion resistance yet remaining compact for narrow energy chains. At the controller end a D-sub 15-pin plug with a solder socket interface mates directly to Bosch Rexroth drive cards, maintaining low-ohmic signal paths. Conductor insulation is rated for a maximum operating temperature of 80 °C, so cabinet air must stay below this threshold to keep dielectric properties stable. The cable is suitable for drag chain use, and it is halogen-free to minimise toxic emission during a fire.
Signal wiring consists of a twisted, shielded control pair with a cross-section of 3x(2x0.25 mm²) StC, limiting crosstalk and maintaining characteristic impedance for differential encoders. Power for the sensor electronics is delivered through two supply lines sized at 2x1.0 mm², supporting low-voltage drops over typical axis lengths. The jacket colour is coded RAL 2003 (Orange) for quick visual identification in mixed cable bundles, and the outer sheath is made from PUR which resists oil, coolant, and welding spatter. Assembly composition INS0701–INK0720–INS0761 indicates the individual connector, transition, and strain-relief parts that are factory-terminated to guarantee continuity and shielding performance.
