40-Core 0.1mm² PLC Cable

Reliable Signal Routing When Panel Space and Time Are Running Out

When a control cabinet starts to look like a bowl of spaghetti, the real cost isn’t the cable. It’s the hours of tracing, the miswired I/O, and the intermittent fault that shuts down a line at 2 a.m. Most of those headaches trace back to cables never designed for dense point-to-point logic wiring. This 40-core 0.1mm² PLC cable strips that risk out of the panel. It packs 40 discrete signal paths into a single, manageable outer jacket, slashing installation time and cutting the scatter-gun of individual control wires that turns commissioning into a forensic job.

Engineers specifying for PLC, DCS, and sensor marshalling cabinets use it to turn cable routing into a repeatable, documented step instead of a source of ongoing uncertainty. The result is faster build, cleaner airflow inside the enclosure, and a far simpler fault-finding path when something eventually needs attention. Not because the cable is magic. Because it was built specifically for high-density low-voltage signal wiring, not borrowed from power distribution.

Why Routing 40 Signals Through One Jacket Changes the Panel Build

40 individual 0.1mm² conductors in a single control cable
A cable like this replaces eight 5-core cables, or four 10-core cables, in a single pull. That means fewer cable entry points, fewer gland plates to drill, and a significant drop in the physical clutter that blocks cooling airflow. For a panel shop, the advantage translates into fewer terminations per signal, which directly lowers the build-hours per cabinet. For the end user, it means a wiring layout that a maintenance electrician can actually read three years later without the original schematic in one hand and a torch in the other.

Compact cross-section designed for 0.1mm² logic-level circuits
0.1mm² copper is more than sufficient for PLC I/O cards drawing a handful of milliamps, but only if voltage drop is kept in check over the real trunk length. By keeping the conductor sizing precise and the insulation wall thin, this cable preserves signal integrity without adding bulk that wastes DIN-rail space. Benefit to the project: more I/O density inside the same enclosure footprint, and no need to upsize enclosures just to accommodate cabling that is over-gauged for the electrical load.

Standardised colour-coded cores with sequential numbering
No one wants to ring out 40 cores by hand after a tight deadline. Factory-printed numbers on each conductor, combined with a repeatable colour sequence, let termination teams work straight from a wire schedule. Setup errors drop, ring-out time collapses, and the panel sign-off moves faster. In multi-panel projects where dozens of identical cabinets are built, this kind of repeatability is a hard cost saving that shows up on the margin.

Flexible strand construction for pull-in and routing
A stiff cable in a cramped wireway forces installers to fight every bend, and that fight leaves bruises on the insulation. Fine-stranded copper, combined with a jacket that stays pliable at workshop temperatures, makes the difference between a cable that routes cleanly around duct corners and one that kinks. Less physical strain on the terminations, fewer latent failures that only appear after thermal cycling.

Strippable outer jacket that doesn’t fuse to the underlying bundle
The minute you apply heat or a blunt stripping tool to a jacket that has bonded to the cores, you lose time and risk nicking conductors. A designed-in layer separation ensures clean jacket removal over any stripping length, whether the cable enters a terminal box or a trunking channel. Benefit: zero time wasted on re-stripping, and a measurable reduction in scrap length at each termination.

Technical Specifications

The table above reflects the common configuration. For detailed electrical, mechanical, and environmental specifications, refer to the official product datasheet. Values such as capacitance, inductance, and jacket dimensions vary with shielding and insulation choices. We supply the full datasheet ahead of sampling so you can verify suitability before physical testing.

Where This Cable Earns Its Keep

• PLC and DCS marshalling cabinets – When dozens of 4–20 mA or discrete signals need to travel between field terminal blocks and the I/O card, the 40-core cable reduces the number of individual pulls and simplifies cabinet wiring schedules.
• Sensor and transmitter wiring in process skids – Oil & gas and chemical skids frequently cram temperature transmitters, pressure switches, and limit switches into tight junction boxes. A single multi-core cable keeps the wiring orderly and speeds up FAT (Factory Acceptance Testing).
• CNC machine and robotic cell control panels – Inside control enclosures subject to vibration and limited space, flexible fine-stranded construction prevents fatigue failures that plague solid-conductor control wiring.
• Building automation and HVAC control panels – Large commercial buildings often run hundreds of low-power digital I/O points from centralised PLCs. A multi-core solution drastically cuts the number of trunk cables pulled through risers and ceiling trays.
• Water/wastewater treatment telemetry cabinets – Panels exposed to humidity and occasional chemical mist benefit from a cable engineered with a clean-stripping jacket and optional moisture-resistant insulation, helping avoid degradation at the termination points.

FAQ

How far can a 0.1mm² conductor carry a 4–20 mA signal before voltage drop becomes a concern?
It depends entirely on the loop resistance and the minimum operating voltage of the field device. With a 0.1mm² conductor, expect a loop resistance around 180–200 Ω/km at 20°C. For a typical 24V-powered transmitter requiring at least 12V at the terminals, you can run several hundred metres before dropping into marginal territory. We provide the exact resistance per km on the data sheet so your electrical engineer can plug the numbers directly into the loop calculation instead of guessing.

Can you supply the cable with an overall shield, and is the drain wire included?
Yes. The braided shield option uses tinned-copper strands at ≥85% coverage and comes with a continuous drain wire for easy termination. Shielded versions are particularly useful when routing low-level analog signals through areas with variable-frequency drives or where the cabling runs parallel to motor power circuits. Let us know the EMI environment during inquiry, and we will recommend whether foil, braid, or both makes sense.

What is the typical production lead time for a 500-metre custom order?
For standard PVC-jacketed 40-core 0.1mm² cable without shielding, we typically hold inventory and can ship within 5–7 working days. Shielded versions or special jacket materials (PUR, LSZH) may require 2–3 weeks depending on current backlog. We are transparent about slot availability before you issue the PO—no optimistic dates given just to win the order.

Do the cores follow a DIN 47100 colour code or a different standard?
Standard production follows a number-printed identification system combined with a base colour sequence. If you need a specific national code (such as DIN 47100, NF C 32-070, or a custom colour table to match your in-house drawings), we can accommodate that with a small MOQ adjustment. The earlier we know, the easier it is to fit in the production schedule.
