19 AWG 2-Core Double Shielded Cable — Built for Signal Integrity, Supplied Direct by the Manufacturer
Signal degradation from electromagnetic interference is not a theoretical risk—it is the root cause of unplanned downtime, erratic sensor feedback, and costly rework on commissioning day. An inaccurate thermocouple reading or a dropped Modbus packet can halt an entire production line before anyone diagnoses the cable. The 19 AWG 2-Core Double Shielded Cable addresses this failure point at the physical layer. Engineered as a direct-fit solution for instrumentation, control, and data circuits, its dual barrier against noise keeps your signal path clean while factory-direct fulfillment shortens your supply chain and consolidates your compliance documentation.
How the Double-Shield Construction Protects Your Measurement Accuracy
Aluminium Foil + Tinned Copper Braid
The cable applies a bonded aluminium-polyester tape as the inner shield and a high-coverage tinned copper braid as the outer shield. This combination creates a continuous Faraday cage that absorbs low-frequency magnetic interference and reflects high-frequency radiated noise. Result: ground loops and crosstalk are suppressed before they can superimpose on your analog signal. Corrupted 4–20 mA loops become a non-issue. Your PLC reads clean values. Every scan cycle.
19 AWG Copper Conductor (0.91 mm²)
Stranded bare or tinned copper in a 19 AWG section gives you the right trade-off between tensile strength and low loop resistance. At 0.91 mm², the conductor cross-section limits voltage drop across long field runs from remote sensors to marshalling cabinets. A conservative DC resistance per kilometer means your transmitter’s terminal voltage stays within specification, removing one hidden variable from commissioning reports. Less drop. Less compensation.
Precision Twisted 2-Core Geometry
The two insulated cores maintain a controlled lay length throughout the entire spool. This mechanical consistency stabilizes characteristic impedance and optimizes common-mode noise rejection. In RS-485 networks, unstable impedance creates reflections that corrupt data frames. This cable prevents those bit errors. Your SCADA panel sees clean telemetry, and your maintenance team stops chasing ghost alarms.
Industrial Jacket Options (PVC, LSZH, PUR)
A single cable run often traverses cable trays covered in cutting oil, exposed rooftop paths under UV, and packed conduits inside control rooms. We stock standard flame-retardant PVC for general plant wiring, low-smoke zero-halogen compounds for public infrastructure, and polyurethane for continuous-flex and abrasion-intensive installations. No need to switch cable types mid-run. Your installation crew pulls one part number, and the jacket compound carries the requisite oil, UV, and flame ratings to satisfy the site safety auditor.

Industry Applications & Scenario Validation
- Process automation (chemical, food, pharma): carries 4–20 mA and HART signals from pressure transmitters and flow meters placed near VFD-controlled pumps. The double shield rejects the VFD’s conducted and radiated emissions.
- Power generation and sub-stations: connects protection relays and current transformers inside high-voltage switchyards. The high-coverage braid attenuates the 50/60 Hz magnetic field to prevent nuisance relay trips.
- Rail and tunnel infrastructure: installed in trackside signaling cabinets and ventilation control panels. LSZH jacket options meet EN 45545-2 requirements for smoke density and toxicity in confined underground spaces.
- Marine and offshore platforms: routes control signals from ballast tank level sensors to the DP control room. A PUR jacket plus tinned copper conductors withstands constant salt spray and occasional hydrocarbon contact without jacket embrittlement.
- Commercial building management: links BACnet MSTP and Modbus RTU controllers across HVAC chiller plants. Repeatable impedance means fewer retransmissions and a commissioning engineer who finishes testing ahead of schedule.

Frequently Asked Questions
Can you supply this cable with a tinned copper conductor for offshore use?
Yes. Tinned copper is a standard option and is strongly recommended for any installation where condensation or saline air is expected. The tin coating prevents galvanic corrosion at terminal blocks, which we see often when bare copper is used in marine and water treatment environments.
What bend radius should be maintained during installation?
For unarmored versions, keep the static bend radius to no less than 8 times the cable’s outer diameter. Dynamic flex installations in drag chains or festoons require a larger radius (12× OD or more) and a PUR jacket configuration. We provide the exact recommended radius on the project datasheet to prevent kinking and shield deformation.
What is the lead time, and can you provide pre-cut lengths?
Standard production lead time runs 10–15 working days for volumes under 30,000 feet. We accept trial orders with no minimum length restriction and supply pre-terminated, labelled drums ready for direct deployment on site. Inventory programs for quarterly releases are also available for routine procurement.
Request a Sample and Project Datasheet
Supply chain efficiency depends on getting the exact cable spec right before the purchase order is cut. Send us your signal type, cable length, and environmental conditions. We will return a complete datasheet, a 3-meter sample, and a landed cost estimate that accounts for your preferred incoterm. This review process eliminates wrong-part arrivals and clears the spec barrier in a single exchange.
