Is Your Control System Suffering from Signal Noise or Cable Failure?
You work in a factory or an automation project. You have expensive sensors and PLCs. But the signal keeps dropping. The data is wrong. You check the wires, and they look messy. They are too stiff to fit in the tight cable chain. The insulation cracks after a few months of movement. Or maybe, electromagnetic interference (EMI) from nearby motors is ruining your data. This is a huge headache. You need a cable that is flexible, strong, and blocks noise. You need a cable that works perfectly in tight spaces and lasts for years. We have the solution. It is the imported Unitronic Liycy shielded cable. It is built for exactly these problems.
What is the Unitronic Liycy 4-Core Shielded Cable?
This is not just a normal wire. It is a professional data and signal cable. It is designed for industrial use. The “Liycy” name means it follows strict German standards (VDE). It has 4 cores inside. Each core is 0.3 square millimeters in size. This size is perfect for low-voltage signals. It is small but strong. The “Shielded” part is very important. It has a metal braid around the inner wires. This braid stops outside noise from getting in. It also stops your signal from leaking out. The cable is very flexible. You can bend it easily. It fits into small drag chains (cable carriers) without breaking. It is used in computer systems, industrial robots, and security systems. It is the go-to choice for engineers who want reliability.

Why is the “Shielded” Feature So Important for You?
Imagine a busy factory floor. There are big motors, welders, and VFDs (Variable Frequency Drives). These machines create a lot of electromagnetic noise. If your signal cable has no shield, this noise travels into your data wires. Your sensor might read “100” when it should be “50”. This causes errors. It stops the production line. The tinned copper braid in the Liycy cable acts like a Faraday cage. It catches the noise and sends it to the ground. It keeps your data clean. This is critical for process control. It is also required for safety systems like alarms or emergency stops. You cannot risk a signal failure in a safety circuit. This cable gives you that peace of mind.
Construction Details: Built for Harsh Environments
Let’s look inside the cable. It is not just one piece of plastic. It is a complex system designed for long life.
- The Conductor: It uses many tiny copper wires twisted together (stranded). This makes it flexible. A solid wire would snap if you bend it. This one can move millions of times.
- The Insulation: Each tiny wire has a PVC coating. This PVC is strong. It resists oil, acid, and chemicals. If your cable touches a little oil, it will not melt or get sticky.
- The Shield: The copper braid is tight. It does not break easily when you flex the cable. It is tinned, so it does not rust (oxidize) over time.
- The Outer Jacket: The black PVC outer layer is tough. It resists abrasion. If the cable rubs against metal, it does not wear out quickly. It is also flame retardant. If there is a fire, it does not spread the flame easily.
Perfect Applications: Where to Use This Cable
You can use this cable in many places. It is versatile. Here are the top uses:
- Industrial Automation: Connecting PLCs to I/O modules. Wiring servo motors and encoders.
- Process Control: Chemical plants, food processing, and water treatment. Where sensors send data to a central computer.
- Security Systems: CCTV cameras, access control readers, and fire alarm panels.
- Robotics: Wiring the arms of industrial robots. It fits inside the moving joints.
- Machine Tools: CNC machines, lathes, and milling machines. It handles the vibration and movement.
- Data Transmission: RS-232, RS-485, and other bus systems.
It works great in dry rooms. It also works in damp or humid places. It is even okay for areas with some oil mist.
Installation Tips for Your Team
Installing this cable is easy if you follow simple rules. Because it is flexible, you do not need huge force to pull it.
- Bending: Do not bend it too sharp. Keep the bend radius bigger than 6 times the cable width. If you bend it too much, you damage the shield.
- Stripping: Use the right stripper. Do not cut the copper strands inside.
- Grounding: This is the most important step. You must ground the shield. Connect the braid to the earth ground at one end (usually the control panel end). If you do not ground it, the shield does not work. It becomes just a useless wire.
- Routing: Keep power cables and signal cables separate. If you must cross them, do it at a 90-degree angle. Do not run them parallel for long distances.
Why Choose This Imported Unitronic Liycy Over Cheaper Options?
You can find cheap cables online. But they often fail. They might use recycled copper. The insulation might crack in cold weather. They might not have a real shield. This Unitronic Liycy cable is imported quality. It meets European VDE standards. These standards are strict. They test the cable for fire, oil, and cold.
- Longevity: It lasts 5 to 10 years in tough conditions. Cheap cables last 1 year.
- Signal Integrity: Your data is accurate. You save money on troubleshooting.
- Safety: It is fire-retardant and safe for people.
- Compliance: If you export your machine to Europe, you need VDE-certified cables. This cable has the paperwork.
The upfront cost is a little higher. But the total cost of ownership is lower. You do not have to replace it often. You do not have downtime because of wire failure.
Frequently Asked Questions About This Product
Q: Is this cable suitable for outdoor use?A: It is mainly for indoor use (dry or damp). If you use it outside, you need to put it in a conduit or UV-resistant pipe. The PVC jacket can degrade in direct sunlight after a long time.Q: Can I use this for power (electricity) instead of signal?A: No. This is a signal cable. It is not rated for high current. Do not use it to power a motor or a light. Use it only for data and low-voltage control (max 500V, but very low amps).Q: What is the difference between Liycy and Liyy?A: Liyy has no shield. Liycy has a copper braid shield. If you have noise problems, always choose Liycy.Q: How do I identify the cores?A: It uses the DIN 47100 color code. You will see colors like Black, White, Red, and Green (or Yellow/Green for ground). This makes it easy to connect to terminals.Q: Do you sell it by the meter or by the reel?A: We can cut it to the exact length you need (custom length). We also have full reels available for bulk projects.
