Product Description:
B&R Automation manufactures the 8CE035.12-1, a pre-assembled hybrid feedback and power lead in the 8BC ACOPOS Cables series. The assembly links ACOPOS servo drives to EnDat encoders and associated motors within enclosed machine frames. By combining servo feedback, supply, and shielding in one harness, the cable streamlines routing and helps maintain signal integrity between the controller and moving axis hardware. It is intended for servo systems that need both motor supply and encoder communication in a single routed assembly.
At a fixed length of 35 m, the harness reaches across large gantries without intermediate junctions that could introduce impedance changes. The mixed-diameter core bundle follows the 5x2x0.14 mm² + 1x2x0.50 mm² layout, separating fine signal pairs from the heavier supply duo to balance flexibility with current capacity. Its outer sheath is formed from PUR, giving abrasion resistance and stable bending behavior in cable chains. Toward the drive, the male 15-pin DSUB connector has a protection rating of IP20, matching standard cabinet environments, while the encoder side carries a 17-pin female Intercontec plug rated at IP66/67 so washdown spray or dust ingress does not affect feedback channels. This connector arrangement supports transitions between enclosed control hardware and more exposed motor-side mounting points.
The internal geometry assigns separate paths to logic and power. The cable uses 10 signal conductors arranged in shielded pairs to minimize crosstalk in incremental and absolute position data, while the supply section uses 2 larger cores for sensor voltage. This separation helps the feedback channels remain stable when adjacent motor-related conductors carry switching currents from the drive. Insulation spacing supports a wire-to-wire dielectric withstand of 1 kV, and the braid-to-core barrier withstands 0.8 kV during wire-to-shield tests. Controlled pair twist and individual foil shields help suppress common-mode noise and preserve encoder accuracy through the full motion range.
