BECKHOFF ZB7101-0100 Câble chaîne porte-câbles EtherCAT P PUR

Product Overview

The ZB7101-0100 (ZB71010100) represents a critical advancement in One Cable Automation (OCA) technology, specifically engineered for the EtherCAT P ecosystem. By integrating high-speed data transmission and 24 VDC peripheral power into a single, compact jacket, this cable eliminates the need for separate power lines, drastically reducing wiring complexity in distributed I/O architectures. Designed for high-flex applications such as robotic arms and CNC pick-and-place systems, its PUR construction ensures long-term resilience against mechanical stress and chemical exposure. In demanding sectors like automotive assembly and semiconductor manufacturing, the ZB7101-0100 serves as a backbone component that minimizes installation footprints while maximizing system uptime through superior signal integrity.

Technical Configuration

The ZB7101-0100 utilizes a specialized hybrid internal structure designed for EtherCAT P (Power + EtherCAT). It features a 4-core Ethernet element (1 x 4 x 0.34 mm) optimized for 100 Mbps communication, alongside two dedicated power cores (2 x 0.75 mm) for Us (system and sensor supply) and Up (peripheral voltage for actuators). To facilitate rapid field identification, the outer PUR jacket is finished in black with a distinctive yellow stripe, conforming to the EtherCAT P coding standard. The "no overall shield" design, combined with its drag-chain suitability, provides the necessary flexibility for high-cycle industrial motion without the risk of internal shielding fatigue or breakage over millions of bending cycles.

Technical Specifications

Technical FAQs

How does the ZB7101-0100 differ from standard EtherCAT cables?

The ZB7101-0100 is an EtherCAT P cable, meaning it carries both data and two independent 24 VDC power supplies. Standard EtherCAT cables only carry data. You must use EtherCAT P specific connectors and junctions with this cable to prevent hardware damage.

What is the significance of the yellow stripe on the jacket?

The yellow stripe is the industry-standard visual identifier for EtherCAT P. It allows technicians to quickly distinguish between standard Ethernet/EtherCAT lines and Power-integrated lines during installation and maintenance.

Is this cable suitable for continuous motion in a cable carrier?

Yes. The PUR jacket and internal stranding are specifically designed for drag-chain applications. It maintains structural integrity under constant bending and high acceleration common in automated production lines.

What is the maximum transmission distance for this cable type?

Following the 100Base-TX standard, the maximum segment length is 100 meters between two EtherCAT P devices. However, voltage drop on the power cores (AWG 18) should be calculated based on your total load to ensure peripheral devices receive sufficient power.

Engineering & Installation Guide

• Bending Radius Management: When installing the ZB7101-0100 within a drag chain, ensure the minimum bending radius of 10 x outer diameter (approximately 90 mm) is strictly maintained. Exceeding this limit will cause premature fatigue of the AWG 22 data cores, leading to intermittent communication CRC errors.

• Strain Relief and Torsion: Ensure proper strain relief at both ends of the cable carrier. The cable must be laid "tension-free" within the chain. Avoid any torsional (twisting) forces during installation, as the hybrid core structure is sensitive to axial rotation which can cause the power and data cores to migrate out of position.

• Environmental Compatibility: The PUR jacket provides excellent resistance to mineral oils, greases, and many industrial chemicals. However, if using in environments with heavy weld spatter or extreme UV exposure, verify additional shielding or protective conduit requirements to prevent jacket degradation.
