Veriflex Profinet Type A Cable

What is Veriflex Profinet Type A Cable?

The Veriflex Profinet Type A Cable is a 300V industrial-grade, double-shielded, 2-pair Ethernet fieldbus cable specifically designed for fixed installation and occasional flexing in automated manufacturing systems operating on Profinet and industrial TCP/IP protocols. Built in strict compliance with IEC/EN 61156-2, IEC/EN 50288-1, and EN 50396, it connects programmable logic controllers (PLCs), industrial PCs, distributed I/O modules, and drive controllers across modern industrial plants.

Unlike standard commercial Category cables, Profinet Type A features solid 22/1 AWG (0.34 mm²) conductors designed to preserve physical symmetry and channel balance along permanent runs. It incorporates an advanced double-screening configuration—Al/PET tape foil combined with a heavy-duty tinned copper wire braid (TCWB)—which guarantees high active and passive noise immunity against electrical noise generated by variable frequency drives (VFDs) and heavy plant machinery. Furthermore, its LABS-free (paint-wetting impairment substance-free) formulation and low smoke zero halogen (LSZH) insulation and jacket make it safe for automotive paint-shop environments as well as public facilities requiring zero halogen acid gas emissions.

Veriflex Profinet Type A Cable Construction

• Conductor: Class 1 solid plain bare copper conductors, 22/1 AWG (nominal cross-sectional area 0.34 mm²) providing low DC resistance and permanent physical stability.
• Insulation: Thermoplastic Low Smoke Zero Halogen (LSZH) compound extruded over conductors to a nominal diameter of 1.43 mm.
• Core Identification: 4 cores (2 pairs) color-coded per industrial Profinet standards: White, Blue, Yellow, Orange.
• Inner Bedding: Extruded Low Smoke Zero Halogen (LSZH) bedding layer with a nominal diameter of 4.2 mm, maintaining core roundness and facilitating rapid mechanical stripping.
• Screen 1 (Foil): Helically applied Aluminium/Polyester tape (Al/PET) delivering 100% electrostatic shielding against high-frequency capacitive noise.
• Screen 2 (Braid): Heavy-duty Tinned Copper Wire Braid (TCWB) providing low transfer impedance and shielding against low-frequency electromagnetic fields.
• Outer Sheath: Rugged Low Smoke Zero Halogen (LSZH) compound, flame retardant and resistant to mechanical wear.
• Sheath Colour: Standard industrial Profinet Green.
• Special Feature: LABS-free (free from silicone and paint-wetting disruptive substances).

Applications

Veriflex Profinet Type A LSZH Cables are engineered for fixed industrial Ethernet infrastructure and machine backbone communication links:

• Profinet IO & Industrial Ethernet Networks: Backbone cabling between main automation controllers, edge gateways, and field devices using standard TCP/IP protocol.
• Automotive Manufacturing & Paint Shops: Certified LABS-free construction ensures zero cratering or finish defects when installed adjacent to robotic painting lines.
• Fixed Cable Trays & Wireways: Stationary cable runs in conduits, enclosed trunking, and open ladders inside industrial processing facilities.
• Public & Enclosed Facilities: Data communication infrastructure in airports, railway hubs, and cleanrooms where zero-halogen fire safety (LSZH) is mandatory.

Specifications & Dimensions

The standard Veriflex Profinet Type A cable is supplied under part number VBUPNA04G5LSGNO in a 2-pair configuration (2P × 22/1 AWG / 0.34 mm²), with an inner bedding diameter of 4.2 mm, a nominal outer diameter of 6.5 mm, and a nominal weight of 74 kg/km.

Frequently Asked Questions

Q: What is the defining characteristic of a Profinet “Type A” cable?
A: Profinet Type A cables are designed specifically for fixed installations and feature solid copper conductors (Class 1, 22/1 AWG) to ensure long-term physical stability, low signal attenuation, and structural alignment, unlike Type B (flexible stranded) or Type C (continuous flexing/torsional) cables.

Q: What does “LABS-free” mean, and why is it important in industrial manufacturing?
A: LABS-free signifies that the cable materials contain no paint-wetting disruptive substances (such as silicones or specific lubricants) that could emit volatile compounds and compromise paint adhesion in automotive body shops and coating facilities.

Q: How does the double screening system protect against electromagnetic interference?
A: The inner Al/PET tape foil provides 100% optical coverage against high-frequency capacitive noise, while the outer tinned copper wire braid provides low transfer impedance against low-frequency inductive fields generated by motors and switchgear.

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.
