Description
Designed for demanding dynamic industrial environments, the Beckhoff ZB7210-0100 raw cable integrates high-speed EtherCAT P communication and robust auxiliary power distribution within a single wear-resistant sheath. This cable features a high-flexibility construction tailored specifically for continuous motion in drag chains and moving machine elements. By combining four Ethernet communication cores with three high-capacity power conductors, it eliminates the need for separate signal and power lines, reducing installation footprint, labor costs, and cable carrier weight in decentralized control architectures.
Features
-
Optimized for Motion: Engineered specifically for drag-chain routing with reliable torsion and bending endurance.
-
Rugged PUR Sheath: Polyurethane (PUR) outer jacket provides exceptional resistance to mineral oils, synthetic coolants, and mechanical abrasion.
-
High-Visibility Identification: Deep black jacket (similar to RAL 9005) with a distinctive red stripe (similar to RAL 3020) for instantaneous identification as an EtherCAT P line.
-
Dual-Function Core Design: Integrates a 4-core Ethernet star quad with three large-cross-section power conductors to service standard 24V DC logic and peripheral power.
Applications
- Decentralized I/O stations utilizing Beckhoff EtherCAT P EP-series box modules.
- Multi-axis robotic arms, gantries, and automated pick-and-place machinery.
- Dynamic material handling, continuous-flex packaging lines, and conveyor tracking systems.

Empirical Engineering Insights
Alternative Models & Compatibility
The ZB7210-0100 is supplied as raw bulk cable. It is fully compatible with standard Beckhoff B23 field-installable connectors. When selecting connectors, ensure you source B23 Series EtherCAT P rated connectors to maintain correct spacing and pin alignment for the AWG 14 power and AWG 22 communication lines. Do not use standard EtherCAT (non-P) connectors, as standard EtherCAT does not support integrated power lines on the communication cores.
Application Pitfalls & Engineering Notes
While the outer PUR jacket is exceptionally tough, avoid exceeding the maximum physical bending limits inside a drag chain. Torsional stress should be eliminated by ensuring the cable is laid flat without twists when first wound into the carrier. Running this cable adjacent to unshielded high-voltage AC motor drives in the same tray should be done with care; although the EtherCAT signal is highly robust, physical separation from noisy motor leads prevents coupling into the unshielded power conductors inside this cable run.
Commissioning & Wiring Tips
When stripping the outer jacket to terminate into a field-mountable connector, use specialized outer jacket strip tools calibrated for 11.1 mm outer diameters to prevent nicking the thin insulation on the 0.34 mm2 communication cores. Ensure that the red identification stripe remains visible outside the cable gland of your connector to allow field technicians to distinguish the safe EtherCAT P network run from standard Ethernet lines at a glance.
Installation Guidelines
CRITICAL WARNING: Prior to terminating, pulling, or adjusting cables, verify that all power sources supplying both communication (Us) and peripheral (Up) networks are fully de-energized. Do not plug or unplug the terminations of this cable under load, as arcing can damage internal contacts and delicate downstream PLC electronics.
1
Unroll the cable directly from the drum before installation. Do not pull the cable over the side of the spool, as this introduces structural twisting that degrades drag-chain life expectancy.
2
Lay the cable loosely in the drag chain. Ensure it occupies no more than 60 percent of the internal cross-section of the carrier cavity to allow lateral movement during high-flexion runs.
3
Secure both ends of the cable with robust strain relief brackets outside the moving sections of the drag chain. Clamp only the outer PUR jacket without compressing the internal cores.
