Are You Tired of “Ghost” Signals and Expensive Downtime?
Imagine this. Your factory floor is running smoothly. Then, out of nowhere, a critical sensor stops working. The PLC shows an error, but the wire looks fine. You check the connections, but everything seems tight. The real problem isn’t visible—it’s happening inside the cable.Cheap cables act like antennas. They pick up noise from motors, VFDs (Variable Frequency Drives), and welding equipment. This noise creates “ghost” signals. Your system reads false data. Machines stop. Production lines halt. You lose money every minute.You need a cable that doesn’t just carry data. You need a cable that defends it. You need the precision of Japanese engineering. We bring you the Kobelco 6-Core 22 AWG Double Shielded Cable. It is not just a wire. It is a fortress for your data. Built in Japan to exacting standards, this cable solves interference problems before they start. It is the ultimate solution for harsh industrial environments where reliability is not optional—it is mandatory.
What Makes This Kobelco Cable Different?
You might see many “22 AWG shielded cables” online. But most of them cut corners. They use thin copper, cheap foil, and weak jackets. This Kobelco cable is different. It is built to Japanese Industrial Standards (JIS).
The “Heart” of the Cable: Pure Copper Conductors
At the center, you have 6 cores of pure, high-conductivity copper. We specify 22 AWG, which equals 0.34 mm² cross-section. Why does this matter?
- Low Resistance: The loop resistance is tight, usually under 110 Ohms/km. This means your signal travels far without losing strength.
- Stranded Flexibility: The conductors are stranded (Class 5 flexibility). They are not stiff solid wires that snap when you bend them. You can route this cable through tight cable chains (drag chains) without breaking the copper inside.
- Oxygen-Free Quality: Japanese manufacturing often uses high-purity copper. It resists corrosion better than standard copper. This ensures a stable connection for 10 or 20 years.
Twisted Pair Geometry: The Secret Weapon Against Noise
This isn’t just 6 random wires. It is a Twisted Pair design. The wires are twisted together in specific lay lengths.
- Cancellation: When wires twist, they create a magnetic field that cancels out external noise. If a motor creates interference, it hits both wires equally. The receiver subtracts the noise, leaving only the clean signal.
- Impedance Control: The twisting keeps the characteristic impedance stable (around 135-165 Ohms for data cables). This is critical for high-speed protocols like PROFIBUS DP or EtherNet/IP. If the impedance jumps, data packets get lost.
Double Shielding: The Ultimate Armor
This is where cheap cables fail. They have one weak foil shield. This Kobelco cable features Double Shielding:
- Individual Pair Shield: Each twisted pair has its own shield (often a Beldfoil or copper braid). This stops crosstalk between the pairs inside the same cable.
- Overall Shield: A second shield wraps around the whole bundle. We use a combination of copper braid and aluminum foil.
- Coverage: The shielding coverage is high (often >90%).
- Drain Wire: Every shield has a tinned copper drain wire. This makes grounding easy and effective. You don’t have to scrape insulation to ground the shield. Just connect the drain wire, and the shield works instantly.
The Jacket: Built for the Real World
The outer diameter is 7.5mm. It feels substantial. The jacket is usually PVC, PUR (Polyurethane), or LSZH (Low Smoke Zero Halogen), depending on your need.
- Oil & Chemical Resistance: In a factory, cables touch coolants, oils, and cleaning agents. This jacket resists swelling and cracking.
- Crush Resistance: The 7.5mm diameter includes a strong inner sheath. It can handle being stepped on or pinched by machine guards.
- UV Protection: If you use this outdoors, the black jacket resists sunlight degradation.

Where Should You Use This Cable?
You shouldn’t waste this premium cable on a simple LED light. This is for critical data and control systems. Here are the best use cases:
1. Industrial Automation & PLC Networks
If you are setting up a PROFIBUS DP or PROFINET network, this is the gold standard. The 150 Ohm impedance matches the bus requirements perfectly. You won’t get signal reflections that crash the network. It handles the high-frequency signals of modern PLCs (like Siemens, Allen Bradley, or Mitsubishi).
2. EtherNet/IP and Industrial Ethernet
With CAT5e and CAT6 prices fluctuating, sometimes you need a ruggedized alternative for short runs inside a cabinet or between machines. The double shielding prevents the high-frequency Ethernet signals from leaking out or being corrupted by nearby heavy machinery.
3. Sensor and RTD/Thermocouple Wiring
This cable is perfect for connecting temperature sensors (Pt100, Type K thermocouples).
- Duplex Elements: You can run two sensors in one cable (using 4 or 6 cores).
- Noise Immunity: Temperature signals are very weak (millivolts). Noise can look like a temperature change. The shielding ensures the temperature reading is accurate.
- Compatibility: It fits standard spring-loaded terminal heads (TE Connectivity style) and M12 connectors.
4. Servo Motors and Drives
Servo systems are noisy. The motor cables generate massive electromagnetic interference (EMI). If your feedback cable (encoder) is near a servo power cable, you need heavy-duty shielding. This Kobelco cable keeps the encoder signal clean, ensuring the motor stops exactly where it should.
5. Audio/Video and Broadcast (Studio Use)
While it’s an “industrial” cable, audiophiles and broadcast engineers love Japanese cable for its low noise floor. It works great for balanced audio lines (XLR) or SDI video runs in environments with lots of RF interference.
Why Buy “Japanese Imported”? The Quality Difference
You might ask, “Why not buy a local cable?” The difference is in the tolerances and the raw materials.
- Consistency: When you buy 1000 meters of Kobelco cable, the first meter is exactly the same as the last meter. The copper diameter doesn’t vary. The insulation thickness is perfect. Cheap cables get thinner halfway through the spool to save money.
- The “Feel”: Pick up a Kobelco cable. It feels dense. The copper is heavy. The jacket is smooth but tough. It doesn’t smell like cheap plasticizers (which evaporate and make the cable brittle).
- Longevity: We have clients using Kobelco cables installed in the 1990s that are still working. They don’t crack in the cold. They don’t melt in the heat. They are an investment, not an expense.
- Testing: Japanese factories test every batch for capacitance, resistance, and shielding effectiveness (transfer impedance). You get a Certificate of Conformity (CoC) with every shipment.
Installation Tips for Best Performance
Even the best cable can fail if installed wrong. Here is how to get the most out of this Kobelco wire:
- Ground the Shield Correctly: This is rule #1. Connect the drain wire to the ground. But do it at one end only usually, to avoid ground loops. If you have high-frequency noise, ground both ends using a capacitor or a special grounding kit.
- Don’t Kink It: Even though it’s flexible, don’t bend it sharper than 75mm radius. A kink changes the impedance and breaks the shield.
- Separate Power and Signal: Don’t run this signal cable in the same tray as 480V power cables. If you must cross them, cross at 90 degrees. Keep at least 300mm distance if possible.
- Use Proper Glands: When the cable enters a control panel, use an EMC cable gland. This clamps the shield to the metal enclosure, creating a 360-degree connection. Don’t just poke the wire through a hole.
Frequently Asked Questions (FAQ)
Q: Is this cable suitable for outdoor burial?A: Yes, if you choose the PE (Polyethylene) jacket option. Standard PVC is for indoor/conduit use. PE is UV resistant and moisture proof.Q: Can I crimp M12 connectors on this 22 AWG wire?A: Yes, but 22 AWG is on the thinner side for field-crimped M12s. It is easier to use pre-molded cables or solder the pins. If crimping, use high-quality tools (like Astro or Weidmuller) designed for fine strand wire.Q: What is the maximum length for a data run?A: For PROFIBUS DP, you can go up to 1200 meters at 9.6 kbps. For EtherNet/IP (100 Mbps), you are limited to 100 meters, just like standard LAN cables, because of the physics of high speed.Q: Do you have 4-core or 12-core versions?A: Yes. Kobelco makes a whole family of these cables. We can source 2-core, 4-core, 8-core, 12-core, and up to 50-pair telephone/data hybrids. The 7.5mm diameter is specific to the 6-core version with double shield, but other core counts will have slightly different diameters.Q: Why is the price higher than Chinese generic brands?A: You are paying for metallurgy and precision. The copper is purer. The shielding coverage is higher. The machine that makes it costs millions of dollars. It’s like comparing a Toyota to a Lexus—both drive, but one is built for perfection.
