Custom 50-Core 0.14mm² Shielded Cable
Precision Signal Transmission in High-Density Installations
Multi-core signal cables fail for predictable reasons. Crosstalk corrupts data. Flex fatigue breaks conductors inside cable chains. Bulk resistance drifts when inferior copper oxidises under heat. Each failure costs you more than the cable itself—it costs you unplanned downtime, diagnostic hours, and replacements scoped months too early. The 50-core 0.14mm² shielded cable eliminates these failure modes by combining dense conductor packing with a consistent shielding geometry that keeps signal integrity stable across the entire service interval. The result is a lighter cable loom, fewer connector terminations, and a bill of materials that refuses to inflate quarter after quarter.
Dense Core Packing Reduces Installed Volume
50 colour-coded 0.14mm² conductors in a compact cross-section.
We strand each core with 18 strands of 0.10mm bare copper—enough to meet the 0.14mm² nominal section without overfilling the jacket diameter. The payoff shows up in drag-chain carriers and robotic dress packs: you route 50 signals through a single cable where competitors would force you into two 25-core assemblies. Less volume means smaller bend radii, lighter e-chains, and fewer cable entry points to seal against washdown.
Aluminised Polyester Tape + Tinned Copper Braid Shielding
A dual-layer shield that blocks both EMI and RFI across industrial frequency bands.
The inner foil wrap provides 100% optical coverage, catching high-frequency noise that spiral shields miss. A tinned copper braid with 85% minimum coverage handles low-frequency magnetic interference and gives you a low-impedance path to ground. For drives cabinets or VFD-heavy plants, this combination keeps 4–20mA analogue signals readable and encoder pulse trains free of ghost counts. You stop chasing noise-induced offsets.
Defined Low Capacitance Between Cores
Core-to-core capacitance held to ≤120pF/m under standard test conditions.
When 50 conductors run parallel, capacitance builds fast. Unmanaged, it rounds off square-wave edges and introduces channel-to-channel delay. Our extrusion process controls the insulation wall thickness uniformly, and the foil shield creates a fixed dielectric reference plane. This keeps propagation delay consistent, which matters when you’re clocking data across 18-metre gantry spans or synchronising multiple servo drives.
Jacket Formulations Matched to the Operating Environment
Standard PVC for dry interiors. PUR for abrasion and oil resistance. LSZH for enclosed public spaces.
No single jacket works everywhere. We offer three material streams so you don’t over-specify or under-protect. The PUR version survives 5 million flex cycles at a 10× cable-diameter bend radius—tested on a TüV-style rolling bend rig. The LSZH jacket meets IEC 60754 halogen-content limits and low-smoke criteria, keeping your rail-signalling or tunnel-lighting projects inside the fire-safety envelope.
Made-to-Length Deliveries, Factory-Terminated on Request
Standard cut lengths from your drawings. Pre-stripped, crimped, or overmoulded assemblies as an option.
Procurement teams that buy fixed reels always pay for scrap. We ship by the metre, to your exact production-run lengths. If your workforce spends more time prepping cables than installing them, ask for terminated assemblies. We strip jacket, foil, and braid; ring solder drain wires; and apply ferrules, D-subs, or M12 connectors on either end. Plug-and-install straight out of the shipping tube.

Industry Applications
- Robotics & Automated Motion – Supplies sensor feedback and control signals along 7-axis robot arms and Cartesian gantries. The dual shield eliminates encoder count errors induced by nearby VFD motor cables.
- Packaging & Food-Beverage Machinery – Withstands continuous high-speed cycling in filling, sealing, and labelling lines. The PUR jacket resists washdown chemicals, synthetic ester greases, and mechanical abrasion from cable chains.
- Power Plant Instrumentation – Carries thermocouple extension signals, RTD inputs, and low-level DC analogue loops inside turbine skids and burner management panels. Low inter-core capacitance prevents signal slope distortion over 30-metre cable runs.
- Rail & Rolling Stock Systems – Connects door control units, passenger information displays, and brake monitoring circuits. LSZH jacket variants meet the smoke-density and toxicity limits required by EN 45545-2.

FAQ
Can you supply terminated assemblies with D-sub or circular connectors attached?
Yes. We have an in-house wire-harness department that strips the jacket, terminates the braid and drain, and moulds or assembles connectors to your pinout schedule. Standard connector types include DB50, HD D-sub, M12, M23, and industrial rectangular connectors. You receive a ready-to-install loom, individually tested for continuity and hipot before packing.
What is the typical minimum order quantity (MOQ), and can we order samples with our own wire colour scheme?
MOQ for standard 50-core PVC cable starts at 300 metres. For PUR or LSZH jackets, MOQ is 500 metres. Engineered samples with a customer-defined colour code usually require a 100-metre trial run. We routinely produce trial batches for functional prototype builds and provide strippability data along with the samples.
How do you control shielding performance in such a high core-count cable?
The key is maintaining a concentric core bundle under the foil wrap. We use a lay-length optimised for bending stiffness, then add a binder tape before applying the aluminium/polyester foil. This prevents core migration and wrinkles that would open gaps in the foil. After braiding, transfer impedance is measured on a network analyser up to 1 GHz. Typical results hold below 10 mΩ/m at 30 MHz, which is sufficient for most serial communication protocols and analogue signals in factory settings.
