Transmitting Clean Signals in Tight Spaces: 4-Core 0.08/0.1mm² Shielded Cable

A single intermittent signal fault in a control loop can idle an entire production line. Tracking down the source—often microscopic insulation wear or EMI coupling into an unshielded multicore—wastes engineering hours and delays commissioning. The 4-Core 0.08/0.1mm² Shielded Cable removes this risk at the physical layer. It combines a tight twist pitch, a full-coverage shield, and a compact outer diameter to secure low-current signal integrity inside junction boxes, drag chains, and instrumentation enclosures where space is limited. The result is fewer noise-induced faults, faster panel wiring, and a bill of materials that meets CE compliance without overspecifying expensive heavy-gauge control cable.

A Shield Designed for Real-World Noise Floors

Full-Pitch Spiral Shield with Drain Wire
The shield wraps at a lay length short enough to maintain coverage even when the cable bends around a 5x OD radius. This geometric consistency blocks radiated EMI from adjacent VFD cables and contactor coils. A tinned copper drain wire runs in continuous contact with the shield, allowing a single-point termination to ground in under three seconds—no foil unwrapping. The benefit shows up first during commissioning: analog 4-20 mA signals hold steady at the PLC input card, eliminating the late-stage troubleshooting that erodes project margin.

0.08/0.1mm² Stranded Conductors
The fine stranding keeps bending fatigue low inside oscillating cable tracks and across hinged control panels. With a conductor cross-section sized for sensor-level currents and LED indication circuits, the cable avoids the excess stiffness of 0.25mm² alternatives. Cabinet builders gain speed because the wire dresses into terminals cleanly without spring-back. Procurement managers see a single SKU that serves most low-power instrumentation runs, reducing the variety of cable reels sitting in stores.

Compact Four-Core Geometry
Four cores laid in a true concentric twist—not a simple planetary lay—produce a near-circular profile. The roundness matters when the cable passes through threaded cable glands and split grommets: the gland nut compresses evenly against the outer jacket, preserving the IP rating of the enclosure. Field engineers can populate crowded cable entry plates without forcing ovalized cables through undersized knockouts. Re-work on site drops.

Flame-Retardant PVC or LSZH Jacket Options
The standard jacket meets IEC 60332-1 flame propagation limits. For enclosed public infrastructure—metro signaling, tunnel ventilation actuators, hospital BMS networks—the LSZH variant emits low smoke density and zero halogen gases. Specifying the correct jacket at the design review prevents a costly re-wire if the authority having jurisdiction enforces low-smoke requirements after installation begins.

Technical Specifications

Where This Cable Is Specified

• Industrial automation panels – routes clean 24 V sensor signals past contactors and relays without letting switching noise couple onto adjacent channels.
• Building management systems (BMS) – connects damper actuators, differential pressure sensors, and valve feedback potentiometers in ceiling-level control nodes where plenum-rated jacketing may be needed.
• Rail signaling and infrastructure – supplies control logic to trackside cabinet relays; the shield blocks traction return current interference when used with single-end grounding schemes.
• Wind turbine nacelle instrumentation – survives constant low-amplitude vibration when routed through pitch control junction boxes; fine-stranded conductors resist work-hardening and breakage.
• Test and measurement racks – carries thermocouple extension signals or strain gauge excitation with a low noise floor from bench to DAQ card; easy dressing through 19-inch rack cable trays.

Frequently Asked Questions

Can you supply this cable with a polyurethane (PUR) jacket for a machine tool application exposed to cutting oil?
Yes. While PVC is the standard stock option, we run PUR-jacketed builds against a minimum order quantity. PUR handles repeated flexing and resists mineral oil degradation better than PVC. Provide your expected bend radius and chemical exposure list during RFQ, and we will confirm dielectric performance under those conditions before sampling.

Does the shield require grounding at both ends?
In most field sensor-to-PLC loops, grounding the shield at one end only—typically at the control panel earth bar—prevents ground-loop hum. The continuous drain wire makes single-end termination fast and reliable. If you are carrying high-frequency digital signals across different ground planes, a hybrid bonding approach using a capacitor at the far end can be discussed during technical review, but the standard recommendation is single-point grounding.

What is the exact outer diameter of the 0.08mm² version?
The finished diameter depends on the jacket compound and wall thickness required for the target voltage rating. We publish nominal dimensions on the final data sheet with a ±0.2 mm tolerance. Provide your gland make and model upfront; we will match the cable OD to the gland sealing range so you avoid stocking additional gland sizes.
