Is electrical noise ruining your expensive equipment?
You have a big problem. Your machines are acting weird. Sensors give wrong readings. The audio has a buzzing sound. Or your control panel keeps showing errors for no reason. This happens because of electromagnetic interference (EMI). Cheap cables act like antennas. They pick up noise from motors, power lines, and other machines. This noise ruins your signal. It stops production. It costs money. You need a cable that blocks this noise. You need a cable that is flexible but strong. You need a cable made to Japanese industrial standards.We have the solution. This is not a cheap generic cable. This is a high-quality, 6-core shielded control cable. It is built to the “VCTF” standard. It uses pure copper wire. It has a special shield to stop interference. It is perfect for control panels, audio systems, and even high-end electronic pianos like Kawai. It works hard so you don’t have to worry.
What makes this 6-core shielded cable special?
This cable is designed for tough jobs. It has six separate wires inside one jacket. This means you can send power and multiple signals in one cable. It saves space. It makes installation easy.Here is the technical breakdown:
- Conductor Material: Pure Copper (Oxygen-Free). Why copper? Because it conducts electricity best. It does not heat up easily. It lasts a long time.
- Conductor Size: 1.25 sq mm (approx 16 AWG). This is the “Goldilocks” size. It is thick enough to carry power for small motors or heavy sensors. It is thin enough to stay flexible.
- Shielding: Aluminum Foil + Copper Braid. Some cables only have foil. Some only have braid. This cable uses both. The foil blocks high-frequency noise. The braid blocks low-frequency noise. It covers all bases.
- Jacket Material: PVC (Polyvinyl Chloride). It is oil-resistant. It is flame-retardant. It is flexible in cold weather and tough in hot weather.
- Standard: JIS C 3306 / VCTF. This is the Japanese standard for flexible cords. It is stricter than many other standards. It ensures safety and durability.
- Voltage Rating: 300V. Safe for most low-voltage industrial and commercial use.
- Temperature Range: -20°C to 75°C (flexible use). It won’t crack in a cold warehouse. It won’t melt near a hot motor.
Where should you use this cable?
You can use this cable in many places. It is a “multi-core” cable. This means it does many jobs. Here are the best uses:
Industrial Control and PLC Systems
This is the most common use. Factories use Programmable Logic Controllers (PLCs). These computers need to talk to sensors. They need to talk to motor drives. If the signal is weak, the machine stops. This 6-core cable is perfect for I/O (Input/Output) bundles. You can run power, ground, and four signal lines in one go. It keeps the factory running smooth.
HVAC and Building Automation
Heating and cooling systems use complex controls. Thermostats, dampers, and actuators all need wires. These wires run through walls and ceilings. They are often near high-voltage power lines. The shield in this cable stops the power lines from messing up the thermostat signal. It ensures the room temperature is correct.
Audio and Intercom Systems
Audio engineers hate “hum” and “buzz.” A bad cable ruins a good speaker. This cable has a tight copper braid shield. It keeps radio frequency (RF) noise out. It is great for connecting PA systems, intercoms, and mixing boards. It keeps the sound clean and clear.
Musical Instruments and Special Electronics
High-end digital pianos, like the Kawai K-500 or BS-2A series, use complex internal wiring. They need stable power for the soundboard and sensors for the keys. A standard cable might cause “ground loop” noise in the audio output. This VCTF cable solves that. It is also great for pedal connections (like the Kawai Pedal Cable No. 1). It provides a clean, noise-free connection for the sustain pedal.
How to install it the right way
A good cable can fail if you install it wrong. Follow these simple rules to get years of trouble-free use.1. Respect the Bend RadiusDo not kink the cable. The datasheet says the minimum bend radius is usually 4 to 6 times the cable diameter. If you bend it too sharp, you ruin the internal geometry. The shield breaks. The wires stretch. Keep it curved, not folded.2. Avoid Parallel Runs with Power CablesDo not run this signal cable right next to a high-current power cable for a long distance. If you must cross them, cross at a 90-degree angle (right angle). This minimizes interference.3. Terminate the Shield CorrectlyThis is very important. The shield must connect to the earth (ground). But do not make a “pigtail” (a long unconnected wire). Fold the shield back neatly. Use a proper connector or ferrule. Attach the drain wire to the chassis ground. A bad shield connection makes interference worse, not better.4. Use Strain ReliefWhen the cable enters a cabinet or a machine, use a cable gland or clamp. Do not let the weight of the cable hang on the electrical connections. This pulls the wires loose over time.5. Label Both EndsAlways put a tag on both ends. Write the core IDs (Core 1, Core 2, etc.). Write the cable part number. If a wire breaks in five years, the next technician will thank you. It makes maintenance fast.
Why buy “Imported from Japan” quality?
Japan has strict safety rules. The PSE (Product Safety Electrical Appliance) certification is mandatory. You cannot sell electrical goods in Japan without it. This cable meets those standards.When you buy this cable, you are buying peace of mind.
- Copper Purity: We use high-grade copper. Cheap cables use Copper Clad Aluminum (CCA). CCA breaks easily and has high resistance. Our copper is real. It is heavy. It works better.
- Jacket Quality: The PVC is premium. It does not get sticky in the sun. It does not get brittle in the frost.
- Consistency: Every meter is tested. The diameter is exact. The shielding coverage is over 85%.
For mission-critical jobs, we recommend a sample test. Order a short reel (like 5 or 10 meters). Do a bench test. Flex it. Terminate it. Put it in your machine. If it works, order the bulk. Buy for duty, not just for price. A cheap cable costs more in the long run because of downtime.

Frequently Asked Questions
Q: Is this cable suitable for outdoor use?A: The standard PVC jacket is good for wet locations and sunlight (UV resistant), but for direct burial or extreme sun exposure, we recommend the LSZH (Low Smoke Zero Halogen) or special UV-resistant black PE jacket version. Contact us for details.Q: Can I use this for a 110V or 220V power line?A: This cable is rated for 300V. It is fine for 110V or 220V control power. However, do not use it for high-current main power lines (like a heater or large motor feed). Use it for the control signal to the motor starter, not the power to the motor itself.Q: What connectors fit this cable?A: Because the core is 1.25 sq mm, you need ferrules (bootlace ferrules) for the ends. You can use screw terminals, spring terminals, or solder them to PCBs. For audio/data, you can crimp RJ45 or XLR connectors if the core count matches.Q: Do you have the Kawai specific plug for the pedal?A: We provide the bulk cable. For the specific 5-pin Mini-DIN plug for Kawai pedals, you would need to crimp it yourself or buy the connector separately. We can supply the cable with the 5-pin connector molded on if you order a custom assembly.Q: What is the minimum order quantity (MOQ)?A: For standard black/white PVC jackets in stock, we can ship from 100 meters. For custom colors or printed jackets, the MOQ is usually 500 to 1000 meters per color. We are flexible for trial orders.
