8BCH0009.1111A-0 by B & R Automation

The 8BCH0009.1111A-0 cable from B & R Automation belongs to the CM16 Motor Cables series. It is a hybrid power-and-signal lead intended to connect CM16 synchronous motors to the corresponding servo drives, supplying three-phase power, auxiliary supply lines, and encoder feedback in automated machinery. Within an installation, the cable supports dynamic routing in drag chains so motion axes can move while maintaining uninterrupted electrical connectivity.

With a total length of 9 m, the assembly suits medium-reach axes in gantries and material-handling robots. Its external diameter of 13 mm ± 0.4 mm permits routing through standard energy-chain separators while still accommodating four power cores with a 1.5 mm² cross section and additional signal pairs. The copper conductors can carry up to 20.2 A when the cable is mounted on a wall, and every core has PVC-free insulation verified to withstand 4 kV wire-to-wire test voltage. For high-cycle applications, the cable is approved for continuous travel at 300 m/min in drag chains without exceeding thermal limits. A braided tinned-copper screen that covers at least 85 % of the circumference provides EMC suppression, while the PUR jacket resists oil and coolant exposure.

Dynamic bending is controlled by a minimum moving radius of 100 mm, preventing conductor fatigue during repetitive cycles. Even at elevated ambient humidity, the insulation maintains a resistivity of 200 M?·km, limiting leakage currents to safe levels. When the 13-pin female SpeedTec hybrid connector is mated, the interface achieves an ingress-protection rating of IP66/67, so wash-down spray will not penetrate the shells. The complete cable weighs 2.2 kg. Separate auxiliary supply wires use a 0.75 mm² cross section for control voltage, supporting encoder circuits in decentralized drive layouts.
