2.8mm 1-Core 0.2mm² Shielded Cable for Signal Integrity in Constrained Installations

Intermittent sensor faults and ghost signals on the factory floor often trace back to one overlooked component. Low-voltage data lines running next to VFD motor cables pick up noise. The result is scrapped batches and hours lost to diagnostics. This 2.8mm single-core shielded cable stops electromagnetic interference right at the physical layer. Clean signal transmission means fewer production halts and lower total cost of ownership in high-density control cabinets.

Core Engineering Highlights

Concentrated Single-Core Shielding
– Feature: 0.2mm² stranded conductor wrapped in an aluminium/polyester foil tape with a tinned copper drain wire.
– Advantage: Provides 100% optical coverage against radiated EMI, keeping the signal path isolated.
– Benefit: Prevents false triggering on proximity sensors and encoders. Your PLC receives uncorrupted data, cutting waste from misreads.

Aggressively Compact 2.8mm OD
– Feature: Finished outer diameter held to 2.8 mm ±0.15 mm.
– Advantage: Slides through crowded cable glands and narrow machine-frame channels without requiring conduit modification.
– Benefit: Makes retrofit jobs on legacy bottling or packaging lines faster. No need to drill out existing entry points.

Stranded Copper Conductor for Flex Zones
– Feature: Bare copper or tinned copper stranding optimized for 0.2mm² cross-section.
– Advantage: Combines the conductivity needed for analog signals with the flexibility to survive continuous movement.
– Benefit: Works inside cable carriers on robotic pick-and-place units without developing hard-fail open circuits. Field replacement rates drop measurably.

Robust Yet Lightweight Jacket
– Feature: PVC compound with good oil resistance; optional PUR for tougher conditions.
– Advantage: Resists incidental contact with cutting fluids and hydraulic oil, plus light mechanical abrasion.
– Benefit: Extends service intervals in CNC machining centers where cables get splashed daily. Reduced cable swaps mean more uptime.

Industry Applications & Scenario Validation

• Industrial Automation: Carries 4-20 mA analog signals from pressure transmitters to junction boxes inside noisy motor control centers. The foil shield blocks stray VFD noise that would otherwise skew sensor readings.
• Weighing & Load Cell Systems: Links strain gauge bridges to summing boxes. Low DC resistance and solid shielding keep millivolt excitation signals stable, ensuring metrological accuracy for batching and filling.
• HVAC & Building Management: Routes through shared trunking with mains wiring for temperature probes and IAQ sensors. Compact diameter simplifies pulling through existing conduits in retro-commissioning projects.
• Test Benches & Data Logging: Connects thermocouple extension leads to DAQ modules. Static and flex ratings suit test rigs that reconfigure frequently, where thick cables are a nuisance.
• Medical Diagnostic Devices: Fits tight enclosures of bench-top analyzers where signal integrity is essential for patient result accuracy. PVC jacket stands up to alcohol-based cleaning agents.

Frequently Asked Questions

For a 2.8mm shielded single-core, what is the minimum bend radius in a moving cable chain?
We recommend a dynamic bend radius no tighter than 15× the outer diameter. That puts you at roughly 42 mm. Staying above this prevents the foil from tearing and the drain wire from snapping under repeated flex cycles. For purely static routing, 8× is acceptable. Always clamp the cable at the chain entry to relieve strain.

Do you supply this cable with a tinned copper braid shield instead of foil?
Yes. While the standard foil construction keeps the weight and diameter low, a tinned copper braid version offers lower shield DC resistance and far superior flex life. Braid makes sense in high-vibration machine tools or when you’re fighting low-frequency magnetic fields. Minimum order quantities apply for custom build. We can send a braided sample on request.

How do you guarantee the conductor coverage stays at 0.2mm² across every reel?
Inline laser diameter micrometers and continuous AC spark testing monitor every meter during extrusion. Statistical process control logs are kept for all batches. This means the resistance stays around 92 Ω/km on copper, which prevents the gain drift in long signal runs that frustrates commissioning engineers.
