Product Description:
The RKG0021 encoder cable is produced by Bosch Rexroth Indramat within the RKG Encoder Cables series. It links high-resolution feedback devices to drive controllers, carrying differential signals alongside auxiliary supply cores so that closed-loop motion axes maintain positional accuracy in industrial automation. By combining twisted signal pairs with separate power conductors, the cable is engineered for continual flexing inside handling robots, portals, and other equipment where uninterrupted encoder communication is critical.
Its mechanical life reaches 5,000,000 bending cycles, supporting sustained operation in dynamic tracks. The conductor set defined as 4x2x0.25 mm² + 2x0.5 mm² separates data and power, reducing crosstalk while feeding the sensor. A drive-side plug in the form of a M23 10-pin connector mates directly with Rexroth drives, whereas the opposite end relies on a 10-pin clamp terminal for panel integration. Control cores can switch up to 300 V, enabling brake or reference signals without extra cabling. Despite the compact 8.8 mm outer diameter, the PUR jacket resists oil, coolants, and abrasion encountered on automated lines.
The cable endures rapid carrier motion because it tolerates a peak linear acceleration of 10 m/s² without shielding fatigue. Installation guidelines specify a minimum static bend radius of 5 × D and a dynamic value of 7.5 × D, allowing tight routing through drag chains while protecting the cores. The sheath material, marked as PUR, is halogen-free to prevent corrosive emissions during fire and appears in RAL 2003 orange for quick identification. Drag-chain compatibility, the halogen-free formulation, and the quick clamp termination on the encoder side shorten maintenance time while meeting safety policies in automated production cells.
