Veriflex DeviceNet Thick LSZH Cable

What is Veriflex DeviceNet Thick LSZH Cable?

The Veriflex DeviceNet Thick LSZH Cable is an industrial-grade, double-shielded, flame-retardant hybrid bus cable rated at a maximum operating voltage of 300V, specifically designed for fixed and occasional flexing indoor applications in CAN-based DeviceNet automation networks. It integrates a dedicated high-frequency data pair and a high-ampacity power supply pair under a single protective violet Low Smoke Zero Halogen (LSZH) outer sheath complying with EN 50575 CPR and IEC/EN 60332-1-2 standards.

Commonly employed as the primary trunk cable in DeviceNet fieldbus topologies, it delivers reliable end-to-end communication between central PLCs, variable frequency drives, motor control centers, and distributed field devices. Its multi-layer shielding architecture—combining individual AL/PET tape screens on each pair with an overall tinned copper wire braid (TCWB)—achieves high electromagnetic compatibility (EMC), suppressing cross-talk between the DC power line and sensitive data signals while blocking external interference with a transfer impedance of ≤15 mΩ/m at 10 MHz. Furthermore, its halogen-free LSZH sheath releases zero acidic fumes and minimal smoke under fire conditions, safeguarding personnel and delicate control room circuitry.

Veriflex DeviceNet Thick LSZH Cable Construction

• Data Pair Conductor: 18/19 AWG (nominal cross-sectional area 0.93 mm²) stranded tinned copper wires offering high conductivity, flexibility, and oxidation resistance.
• Power Supply Pair Conductor: 15/19 AWG (nominal cross-sectional area 1.93 mm²) stranded tinned copper wires engineered for low-resistance DC power delivery.
• Data Pair Insulation: Foam-Skin Polyethylene delivering low dielectric loss, stable 120-ohm characteristic impedance, and a low mutual capacitance of 40 nF/km at 800 Hz.
• Power Pair Insulation: Solid Polyethylene compound providing mechanical toughness and electrical insulation.
• Individual Pair Shield: Aluminium/Polyester tape (AL/PET) applied over each pair to prevent internal inductive and capacitive cross-talk.
• Drain Wire: Continuous tinned copper drain wire in direct contact with the aluminum foil for convenient, low-impedance grounding.
• Separation Layer: Helically wrapped Polyester (PET) tape providing structural binding and dielectric isolation.
• Overall Shield: Heavy-duty Tinned Copper Wire Braid (TCWB) delivering superior low-frequency magnetic shielding and high tensile strength.
• Outer Sheath: Thermoplastic Low Smoke Zero Halogen (LSZH) compound, flame-retardant per IEC/EN 60332-1-2.
• Core Identification: Data Pair: White and Blue; Power Supply Pair: Black and Red.
• Sheath Colour: Standard industrial Violet.

Applications

Veriflex DeviceNet Thick LSZH Cables are engineered for critical communication backbones and data-power links across automated manufacturing lines and processing plants:

Frequently Asked Questions

Q: What is the difference between DeviceNet “Thick” trunk cable and “Thin” drop cable?
A: DeviceNet Thick cable utilizes heavier conductor gauges (18 AWG data, 15 AWG power) and double shielding to serve as the main high-capacity trunk line for distances up to 500 meters with minimal signal loss. DeviceNet Thin cable uses lighter conductors (typically 24 AWG data, 22 AWG power) and higher flexibility, specifically suited for shorter drop links (up to 6 meters) connecting individual devices to the trunk.

Q: What are the functional advantages of Foam-Skin Polyethylene insulation on the data pair?
A: The microcellular cellular structure of Foam-Skin PE lowers the dielectric constant, ensuring reduced mutual capacitance (40 nF/km) and low attenuation across high frequencies (1.25 dB/100m at 1 MHz). The solid skin layer provides crush resistance, preserving precise conductor spacing and stable 120-ohm impedance.

Q: Why does the cable incorporate both individual pair screens and an overall braid?
A: The individual AL/PET foil screens prevent internal cross-talk between the DC power supply lines and high-speed data pairs. The overall tinned copper wire braid (TCWB) protects against external industrial low-frequency electromagnetic fields, achieving a low transfer impedance of 15 mΩ/m at 10 MHz.

Q: What international payment terms does Huadong Cable accept for automation project orders?
A: We accept standard international commercial payment terms, including Telegraphic Transfer (T/T, with 30% advance deposit and 70% against shipping documents) and 100% Irrevocable Letter of Credit (L/C) at sight.
