The Real Problem: Signal Noise Costs You Money
You know how frustrating it is when a new car’s sensor gives a false error code. Or when the reverse camera screen glitches for a split second. These small issues often come from one big cause: bad cables. Cheap cables act like antennas. They pick up noise from the engine and other wires. This is called Electromagnetic Interference (EMI). In modern cars, data moves fast. If the signal is weak or noisy, the system fails. You get warranty claims, returns, and angry customers. You need a cable that stops the noise before it starts. You need a cable built for the harsh environment inside a vehicle.
Why This German Dacar® Cable Is the Solution
This is not just a generic wire. This is a genuine LEONI Dacar® product imported from Germany. LEONI is the world leader in automotive cables. They make cables for top brands in Europe and North America. This specific cable is designed for high-speed data. It uses a special construction to kill noise. It has two layers of protection. We call this “double-shielded.” The first layer is a foil shield. The second layer is a copper wire braid. This combination blocks noise from getting in and signal from leaking out. It ensures your data reaches the control unit perfectly, every time.
Technical Specs Made Simple
You don’t need a PhD to understand these numbers. Here is exactly what you get, broken down simply:
Core Construction Details
- Cores: 4 individual copper wires.
- Cross-Section: 0.14 square millimeters (mm²). This is the perfect size for data signals. It is thin enough to bend easily but thick enough to carry power and data together.
- Stranding: The copper is made of many tiny wires twisted together. This makes the cable very flexible. It is “highly flexible.” You can route it around tight corners in the dashboard without breaking it.
- Shielding: Double shield. Foil shield (Code B) + Copper wire braid (Code C). This is the heavy-duty protection against noise.
- Plating: The copper is tin-plated (Code SN). Why? Because tin does not rust. Copper oxidizes over time, which kills the signal. Tin keeps the connection strong for years, even in humid or salty environments.
- Cable Type: Star quad construction. The 4 cores are twisted in pairs in a special star shape. This cancels out interference from neighboring pairs.
Performance Data
- NEXT (Near-End Crosstalk): This measures how much signal leaks to other wires at the start of the cable. Our cable has very low NEXT. It keeps signals separate.
- FEXT (Far-End Crosstalk): This measures interference at the receiving end. Again, this cable scores very high marks.
- Impedance: Matched for high-frequency data transmission (typically 100 Ohm for twisted pairs). This prevents signal reflection (ghosting).
Where to Use This Cable (Real World Scenarios)
This cable is a workhorse. You can use it almost anywhere in the vehicle that needs clean data. Here are the top use cases:
ADAS and Safety Systems
Advanced Driver Assistance Systems (ADAS) need perfect data. Lane keeping assist, automatic braking, and blind-spot detection rely on sensors. If the cable picks up engine noise, the system might disable itself. Use this 4-core 0.14mm² cable for:
- Radar sensors.
- Lidar units.
- Camera modules (especially 360-degree surround view).
- Ultrasonic parking sensors.
Infotainment and Navigation
Modern dashboards are full of screens. HDMI, LVDS, and Ethernet signals need to travel from the main computer to the display. This cable handles the high bandwidth. It stops the video from stuttering. It is great for:
- GPS navigation units.
- Rear-seat entertainment screens.
- Digital instrument clusters (the screen behind the steering wheel).
OBD and Diagnostic Ports
When a mechanic plugs in a diagnostic tool, they need a stable connection. A bad cable means “Communication Error.” This cable ensures the tool reads the error codes correctly on the first try. It is robust enough to handle the frequent plugging and unplugging at the OBD port.
Industrial and Heavy Machinery
It is not just for cars. This cable is great for:
- Agricultural machinery (tractors, harvesters).
- Construction equipment (excavators, cranes).
- Mining vehicles.These machines have huge electric motors that create massive interference. The double shield is essential here.
The “Tin-Plated” Advantage: Why It Matters for Export
You are doing international business. Your products might sit in a shipping container for weeks. Or they might be installed in cars in coastal areas with salty air. Bare copper turns green and corrodes quickly. This increases resistance and kills the data signal. Our cable uses tin-plated copper (SN). Tin is resistant to corrosion. It acts like a shield for the copper itself. This means:
- Longer Shelf Life: You can stock it without worrying about it degrading.
- Better Resale Value: Your customers see “German Quality” and “Tin-Plated” and trust the product more.
- Fewer Returns: No corrosion means no connectivity issues a year down the road.
Why Buy From Us? (The Business Case)
You might find cheaper cables from local factories. But remember the pain of returns. A 0.50savingonacablecancostyou50 in warranty claims. We offer:

Frequently Asked Questions (Quick Answers)
Is this cable flexible enough for tight spaces?Yes. It uses highly flexible stranded copper (Class 5 or 6 stranding). It bends easily around frames and pillars.Can I use this for both power and data?Yes, but check the amperage. For 0.14mm², it is best for low-current data lines (up to 2-3 amps). If you need high power (like 10 amps for a motor), you need a thicker cable (like 1.5mm² or 2.5mm²).What is the difference between “Foil” and “Braid” shielding?Foil is 100% coverage and blocks high-frequency noise. Braid is a mesh that blocks low-frequency magnetic fields. Having both (Double Shield) gives you the best protection possible.Do you have the datasheet (PDF)?Yes. We have the full LEONI Dacar® datasheet in English, German, and Chinese. It includes the NEXT/FEXT charts and dimension drawings. Contact us to download it.
