34-Core 0.1mm² Shielded Cable
In cramped control cabinets and dense cable trays, the margin between stable data transmission and intermittent failure is often measured in fractions of a millimeter. Signal crosstalk, electromagnetic interference, and conductor fatigue turn multi-conductor runs into a liability. The 34-core 0.1mm² shielded cable eliminates that trade-off. It packs high-density signal routing into a single, flexible assembly. The braided shield layer rejects ambient EMI. The result is cleaner signal integrity and reduced callbacks on sensitive control and instrumentation loops.
Conductor Build & Flex Life
High-density multi-strand copper conductors don’t just carry current. They survive the repeated torsion and vibration common in automated equipment. We use oxygen-free copper strands with a finely controlled lay length. This geometry distributes bending stress evenly across the core bundle.
That matters in cable tracks. Solid or coarse-stranded alternatives work-harden fast. Cracks propagate. Resistance spikes. Your commissioning checklist becomes a troubleshooting marathon. These conductors remain compliant over millions of low-radius flex cycles. We’ve tested this.
Shield Coverage & EMI Rejection
A tinned copper braid with minimum 85% optical coverage wraps the core bundle. This isn’t foil. Braid offers lower DC resistance, a reliable drain path, and survives connector backshell terminations without tearing. The mechanical toughness matters as much as the shielding math.
In a factory floor environment, VFD drives and switching relays inject broadband noise into adjacent cables. A loose foil wrap with a flimsy drain wire invites ground loops. The braid here provides a circumferential ground reference. Differential signals stay clean. 4-20mA readings don’t wander. Encoder counts remain accurate.
Jacket Compound Selection
The outer jacket carries the most practical burden. We default to a matte PVC compound with a durometer selected for industrial routing—flexible enough to dress neatly, tough enough to resist cut-through from cable tie tension. For wet bays or outdoor junction boxes, specify a polyurethane jacket. It laughs off mineral oil, cutting fluid, and UV exposure.
Markings are meter-indexed and permanent. No inkjet smudges that disappear after three months and a few splashes of cleaning solvent. Procurement teams auditing installations six months later can still read every character.
Strip Length & Assembly Efficiency
Each core uses a distinct color and sequential numeric coding. No pairs share ambiguous stripe patterns. Termination errors drop when the assembler isn’t squinting at faded magenta versus faded violet.
A thin, tough insulation wall lets you strip all 34 conductors in a single operation with a properly set rotary stripper. Cycle time per connector drops. That compound effect across a 500-unit production run pays for the cable.

Industry Applications
- Industrial Automation & Robotic Cells. Signal umbilicals on moving gantries and robot arms where continuous flex and electrical noise immunity are non-negotiable. The compact OD leaves more tray space for power cables.
- Test & Measurement Instrumentation. Multi-channel data acquisition systems routing thermocouple compensation signals, strain gauge bridge outputs, or low-voltage analog sensor data back to a DAQ chassis without introducing stray EMF.
- Railway Signaling & On-Board Systems. Inside rolling stock control cabinets where fire performance to EN 45545-2 may be required. Low-smoke, zero-halogen jacket formulations can be applied on request.
- Medical Diagnostic Equipment. Patient-connected monitoring carts and scanning tables that demand high conductor density in a lightweight, flexible cable with reliable shielding.
- Semiconductor Fabrication Tools. Cleanroom robotics and wafer handling modules where outgassing limits and particle-shedding constraints dictate jacket material and surface finish.

FAQ
You offer this as a custom manufacturer. Can you adjust the core count, wire gauge, or jacket material for a specific project?
Yes. The 34-core configuration here is a frequently requested baseline. We regularly modify conductor size (down to 0.05mm² or up to 0.35mm²), add supplementary shielding layers, or switch to PUR, FEP, or LSZH jacketing. Minimum order quantities adjust based on the BOM novelty. For a fully custom build, we submit a first-article sample and full compliance datasheet for your sign-off before production ramp.
What’s the minimum bending radius I should design for in a moving cable track?
Under dynamic conditions, maintain a minimum bend radius of 12 times the outer cable diameter. For a cable with a nominal 8mm OD, that gives you roughly a 96mm bend radius. Tighter bends accelerate conductor strand fatigue even if the jacket shows no immediate damage. We also recommend a strain-relief layer inside the jacket for high-acceleration, short-stroke trajectories. Ask our engineers to review your track layout.
Can this cable be pre-terminated with D-sub, M12, or custom over-molded connectors?
We provide pigtail stripping and tinning as standard for users who terminate in-house. Pre-terminated assemblies with high-density D-sub connectors (37-pin or 50-pin), ring-style, or custom over-molded multi-connector fan-outs are available. Send us your pin-out table. We return a build drawing within 48 hours for confirmation. This saves your techs hours per panel and eliminates cross-wiring rework.
Request a Production Sample
Spec sheets only take a conversation so far. We recommend placing a pre-production sample order against your target mechanical and electrical requirements.
Tell us your jacket preference, expected bend radius, ambient temperature range, and any regulatory standards that must appear on the test certificate. We ship a meter-indexed sample with a full dimensional report.
