Product Description:

The RKG0016 is an encoder feedback cable manufactured by Bosch Rexroth Indramat and supplied within the RKG Encoder Cables series. It links an M23-style feedback device to a controller so position data can move reliably between servo axes and drive electronics in industrial automation cells. A polyurethane sheath protects the conductors from oil and abrasion while the cable maintains signal integrity over machine lengths that experience constant motion.

Mechanical durability begins with a life rating of 5,000,000 bending cycles in drag-chain applications. When routed statically, the cable must maintain a minimum bend radius of 5 × D; during continuous motion, the minimum radius increases to 7.5 × D to limit conductor fatigue. The outer diameter measures 10.0 mm, making it easy to size gland plates and energy-chain partitions. Internally, the cable uses three 0.25 mm² conductors, three twisted data pairs with 0.25 mm² conductors, and two 1.0 mm² supply cores. A jacket made of PUR offers cut resistance and flexibility, and the formulation is halogen-free to reduce the release of corrosive gases during a fire.

The cable has a control potential rating of 300 V, allowing direct connection to standard encoder power circuits. The controller end terminates in a D-Sub 15-pin socket, while the sensor end uses a field-ready M23 17-pin socket; this fixed connector pair prevents pinout mismatches. Signal lines made with 0.25 mm² copper have a resistance of 83.0 Ω/km, whereas the heavier 1.0 mm² supply cores have a resistance of only 19.3 Ω/km, minimizing voltage drop over long runs. The polyurethane insulation tolerates repeated movement while protecting the internal conductors against mechanical wear. Its halogen-free composition also limits corrosive smoke when the cable is exposed to fire. The cable can carry encoder communication in high-cycle gantries, pick-and-place arms, and other motion platforms where repetitive flexing occurs.
