Product Description:

8BCM0009.3111A-0 is supplied by B&R Automation as a hybrid motor cable in the 8BC ACOPOS Cables series. The assembly combines power and feedback lines in a single sheath, and it connects ACOPOS servo drives to matching motors within automated machinery. By routing both energy and encoder conductors through one cable, installation time is reduced and cabinet space is conserved while maintaining deterministic signal integrity.

The cable core layout is 4 × 1.5 mm² + 2 × 2 × 0.75 mm², indicating four conductors sized for phase power and two twisted signal pairs for encoder channels. When fully mated with its 8-pin female speedtec motor connector, size 1, the assembly achieves a protection level of IP66/67 when connected, so washdown liquids or airborne dust do not penetrate the interface. Copper power conductors present a maximum loop resistance of ≤13.7 Ω/km, limiting voltage drop along extended machine axes. Under fixed routing on a mounting panel, the cable may carry 15.2 A, allowing standard ACOPOS drive ratings to reach the motor without thermal overload. Continuous motion is supported between -20 °C and +80 °C, so the cable can travel through typical ambient and machine-generated temperature zones.

Electrical durability is established by a 4 kV wire-to-wire test, confirming insulation strength between adjacent cores during transient overvoltage events. Longitudinal leakage remains low, with an insulation resistance of ≥100 MΩ·km that helps preserve encoder accuracy on high-impedance inputs. For differential feedback conductors, a loop resistance of ≤26.7 Ω/km helps maintain signal amplitude at the drive input over the full catalog length. The PVC outer jacket resists mineral oils and conventional coolants, and the cable shielding is bonded to the connector housing to divert noise toward the drive ground plane.
