Is Electrical Noise Killing Your Machine’s Performance?
You know the feeling. You install a new system, everything looks perfect, and then the sensors start acting weird. The data jumps around on the screen. The robot arm stops for no reason. You check the machine, but the machine is fine. The problem is invisible. It is electrical noise.In a factory, big motors and welding equipment create a storm of electromagnetic interference (EMI). If your signal cables are not protected, this noise gets into the wires. It messes up your data. It causes false alarms. It stops production. And it costs you money every minute the line is down.You also have physical problems. Conduits are tight. Bending space is small. If you use a stiff cable, it breaks. If you use a cheap cable, the jacket cracks when it rubs against metal. You need a cable that is tough on the outside but flexible on the inside. You need a cable that blocks noise and fits anywhere.
The Solution: German-Made UNITRONIC LiYCY Shielded Cable
This is not just a wire. This is a precision tool for your control systems. We bring you the UNITRONIC LiYCY series directly from Germany. It is the industry standard for low-frequency data and control signals.Why do engineers choose LiYCY? Because it works. It has a special shield that wraps around all the inner wires. This shield catches the noise and drains it to the ground. Your signals stay clean. Your data stays accurate. The “Li” stands for signal cable. The “Y” stands for PVC insulation. The “C” stands for shielded (C stands for “Cu” or copper shield in German standards). The last “Y” means PVC outer sheath. It is a code for quality.This specific product has 24 cores (12 pairs). Each core is 0.25 square millimeters (24 AWG). It is the perfect size for carrying multiple signals without taking up too much room. It is flexible, strong, and built to last.
What Makes This Cable Special?
You might see other cables that look the same. But the details matter. Let’s look at the build quality.
The Shield That Actually Works
Some cables have a cheap foil wrap. It tears easily. This cable uses a braided shield made of tinned copper wires. It is like a mesh net around the wires. It covers almost 100% of the cable. It stops radio frequency interference (RFI) and electromagnetic interference (EMI).The copper is tinned. This means it has a thin layer of tin. Why? Because tin stops the copper from rusting. If you use this cable in a damp room or a place with chemicals, the shield stays strong. It ensures grounding works for a long time.
Flexible Stranded Conductors
Look inside the gray jacket. You will find 24 wires. But they are not solid rods. They are made of many tiny copper threads twisted together. We call this “stranded.”Solid wire breaks if you bend it too much. Stranded wire bends easily. You can pull this cable through tight cable chains (drag chains) on a moving robot arm. It will not snap. It will not fatigue. The fine wires (extra fine stranding) make sure the signal travels smoothly even when the cable is moving.
The DIN 47100 Color Code
Wiring takes time. If every wire is black or white, you spend hours testing them. This cable uses the German DIN 47100 color standard.You get distinct colors for the pairs. Usually, you have a base color and a stripe color. For example, Blue/White, Orange/Black. It makes connecting to terminals and PLCs fast. You do not need a manual to find wire number 12. You just look at the color. It saves you labor hours and prevents mistakes.
Tough PVC Outer Sheath
The outside layer is Polyvinyl Chloride (PVC). It is not soft like rubber, but it is tough. It resists oil, acids, and alkalis. If a hydraulic hose leaks a little oil, this cable jacket won’t dissolve.It is also flame retardant. If there is a short circuit and a spark, the cable will not catch fire easily. It meets the VDE 0472 standard (IEC 332.1). In many countries, you are not allowed to install non-flame-retardant cable in buildings. This cable passes the test.

Where Should You Use This Cable?
This cable is a workhorse. You will find it in almost every industry. Here are the top places we sell it:
Industrial Automation and PLCs
This is the home of the LiYCY. Connect your Programmable Logic Controller (PLC) to your sensors and actuators. The shield stops the heavy machinery noise from corrupting the logic signals. It keeps the factory running 24/7.
Robotics and CNC Machines
Robot arms move constantly. Standard cables fail after a few months of twisting. The LiYCY is flexible. It handles the movement of servo motors and encoder lines. It is also great for CNC machine tool wiring where space is tight and coolant fluids are present.
Process Control and Instrumentation
Do you have a control panel with scales, flow meters, or pressure sensors? Use this cable. It is perfect for 4-20mA current loops. The twisted pairs ensure that both wires in the pair pick up the same noise, which the receiver then cancels out.
Building Technology and Audio
While it is an industrial cable, it works for low-voltage building tech. Use it for fire alarms, stage lighting control (DMX), or intercom systems. The DIN colors make it easy for electricians to wire up junction boxes.
The “LiYCY (TP)” Option
If you have very high interference, ask about the LiYCY (TP). The “TP” means Twisted Pair. In that version, the 24 cores are twisted into 12 pairs individually, and then shielded. It is even better at stopping noise. But for most general uses, the standard braided LiYCY is more than enough.
