Custom Industrial Cable Assembly Made to Last in Harsh Environments
Custom industrial cables outperform standard cables because they’re built to last long term in tough conditions.
Your needs determine the features of your custom cables. That includes voltage ratings, shielding levels, jacketing materials, bend radius and how much heat the cable can handle.
WellPCB manufactures custom industrial cables for industrial automation, OEM machinery, medical equipment, and fiber optic systems.
These fully custom cables come with high performance copper or hybrid conductors, polymer insulation and shielding to block signal noise and withstand wear.
All assemblies meet IPC/WHMA-A-620 Class 3 standards for mission-critical environments where reliability is not an option.
- Custom cable assemblies for factory systems, robots, medical devices, and automotive equipment
- Copper cables with XLPE or PVC insulation and full foil-braid shielding
- No minimum order quantity for one-off prototypes or full production runs

Custom Industrial Cable Assemblies for Demanding Applications
Custom industrial cables and wiring harness carry power, signal and data between different types of machines. They’re used in almost every industrial environment for their reliability.
We build our cable assemblies to perform trouble free under high loads, vibration and EMI. Exact specifications depend on the routing, shielding and jacket requirements for the application the cable will be used in. No extra length or unnecessary features included.
Our technicians use materials like copper cable, XLPE insulation and foil-braiding shielding so each cable will withstand temperature swings and mechanical pressure.
Looking for a custom industrial cable manufacturer you can trust? WellPCB checks all the boxes. Our products run machines in the automation, medical, automotive and aerospace industries, proving their strength and performance. Every cable comes with test data to prove it’s been tested for real world use.
Our Industrial Cable Manufacturing Capabilities
WellPCB makes every industrial cable and industrial cable assembly from your technical drawings, samples or specifications. Our manufacturing process is controlled to meet all mechanical, electrical and dimensional requirements, and we can provide full traceability to prove it.
We support low voltage power cables (12V to 48V), multicore signal cables, LVDS interconnects, micro coax, and hybrid round-to-FFC lines.
Depending on layout and insulation type, we can handle conductor counts from 2 to 64 and OD sizing from 2.5 mm to 18 mm.
Every material in your custom industrial cables is sourced to your specs. We offer a choice of Class 5 or 6 flexible stranded copper cable conductors.
Our XPLE insulation is -40 °F to 257 °F (-40 °C to 125 °C). PVC options are -14 °F to 194 °F (-10 °C to 90 °C).
If you choose a halogen free jacket, each one meets UL VW-1 and IEC 60332-3-24 flammability ratings. They’re also tested for Shore A hardness per ASTM D2240.
Your cable’s shielding configuration can be 100% aluminum foil, 90 to 96% tinned copper braid, or a hybrid of both.
If you’re ordering a triaxial or fiber optic cable, we can add steel braid or drain wire structures.
All shielding is tested to <5 mΩ loop resistance and ≥90 dB attenuation across 10 MHz to 1 GHz to make sure they can handle EMI.
We can source any connector you prefer including ACES, JST, DF9, IPEX and open flying leads. Crimping, soldering and IDC application depends on your spec.
Once built, we’ll verify them against your original pin map using multichannel continuity testing. Our processes follow IPC-A-620 Class 3 visual and mechanical inspection rules.
We do full-length inkjet jacket printing, heat-shrink tags, serial markings, and barcoded sleeves.
All custom wire and cable markings meet UL (≤24 in intervals) and ANSI/EIA-455-95A abrasion requirements.
If you want part-level tracking or brand-specific identifiers, let us know upfront, and we’ll arrange it.
To add abrasion, impact and tension protection we offer Kevlar overbraid (1500 to 3500 denier), flame-barrier sleeving (UL rated) and corrugated steel armor with ≥1,000 lb/in² radial strength.
Once applied, we’ll test the cable to ensure it meets pull-force thresholds and bend radius (minimum 5× OD) as specified in your spec.
We test milliohm resistance, continuity and dielectric to withstand (1500 VDC at ≤1 mA leakage).
For high frequency cable assemblies, we use TDR (rise time <250 ps). We also do flex cycle, crush and tensile testing.
If you want the test results included with your delivery, we can send you job records with your custom industrial cables.
We handle prototype quantities (as low as 5 units) and mass production up to 50,000 or more units.
As a high-capacity industrial cable manufacturer, our production process uses automated jacket preparation, cutting, stripping, and crimping machines, and inline verification tools.
We keep dimensional tolerances to IPC requirements, with serialized job tracking throughout all manufacturing processes.

Custom Industrial Cables Client Feedback
As an R&D manager, I have had an outstanding experience working with WELL-PCB. For many years, our company has entrusted them with the production, assembly, and programming of the boards developed in our R&D unit, and they have consistently exceeded our expectations.
Hamid Reza Moshayedi
R&D Manager
Their work is very impressively perfect. Today, when they check our company PCB board after assemble. They found a fake short point which many engineers has never found in the past years. But that is just designed so. The PCB board quality is excellent. Their service is also excellent.
MikeZ
My friend introduced WellPCB to me, the first try, a little look forward to. I ordered a 47*72 10ps PCB, and I can’t wait to receive my PCB. So I used expedited service and received my PCB in three days. I tested and soldered the PCB, Quality is really good, silkscreen, plating also great.

Custom Industrial Cables Manufacturer FAQs
What are industrial cables?
Industrial cables are electrical products used to distribute power, data, or control signals between machines or systems. Manufacturers create these cables for high reliability in environments with temperature changes, high levels of vibration, mechanical stress, or electromagnetic interference (EMI).
What are custom industrial cables used for?
Manufacturers recommend custom industrial cables when standard cables won’t be good enough for harsh conditions. Products in the automotive, robotics, energy, and medical industries need extra strength.
Why choose a custom industrial cable over a standard one?
Custom cables meet the exact performance and installation specs you need, so they include everything you need and nothing you don’t. This improves fit and function, and also reduces failure rates over time.
How do you handle component obsolescence for long-life custom cables?
Our technicians constantly monitor the availability of connectors, jackets, and wire and cable material. If any component becomes unavailable, we’ll provide a backward-compatible match with validation data.
Do you offer custom cables with integrated active or smart features?
We don’t stock cables with these features or help you design cables with these features. We can, however, build custom industrial cables with these features, as long as the active components are supplied by the customer.
