Is electrical noise ruining your signal? Do your cables break easily when bent?
You work with sensitive machines, audio systems, or control panels. You know the problem. A motor starts nearby, and suddenly your data screen glitches. Or you try to pull a cable through a tight conduit, and the jacket cracks. Cheap cables cause downtime. They pick up interference (EMI/RFI). They are stiff and hard to install. You need a wire that protects the signal and lasts a long time. You need a cable built to German industrial standards.This is not just a wire. It is a precision tool for your equipment. We are talking about the LiYCY 4×0.25mm² shielded cable. It is the industry standard for low-frequency data and signal control. It solves the noise problem. It solves the durability problem. It is made for real-world factories and installations.
What makes this LiYCY 4×0.25 cable special?
This cable follows the strict DIN VDE standards from Germany. It is designed for data transmission in the low-frequency range. Think of it as a shield for your electrical signals.The core of the cable is made of bare copper. We use fine-wire stranding (Class 5 flexibility). This means the copper is not one solid stick. It is many tiny wires twisted together. This makes the cable very flexible. You can bend it around corners without damaging it. The minimum bending radius is 10 times the outer diameter when moving. For fixed installation, it is only 5 times the diameter.The insulation is PVC (Polyvinyl Chloride). It is robust and resistant to oil and chemicals. The outer sheath is grey (RAL 7032). It is flame retardant according to IEC 60332-1. If there is a fire, the cable does not spread the flame. It is also self-extinguishing.The most important part is the shield. We use a tinned copper braid. The coverage is high (around 85% or more). This braid acts like a cage. It stops outside electromagnetic waves from messing up your data. It also stops your signal from leaking out. The braid is tin-plated. This prevents corrosion. It keeps the shield working even in damp or wet spaces.

Where should you use this 4-core shielded wire?
This cable is a workhorse. It fits in many places because it is compact and strong. You can use it for fixed installation or occasional movement. But do not use it in open air with direct sunlight (UV). It needs to be in pipes, trays, or inside machines.Here are the top use cases:##### Machine Tools and ManufacturingThis is the home turf for LiYCY. Use it for CNC machines, robot arms, and assembly lines. It connects sensors to PLCs. It transmits control signals to motors. The small 5mm diameter saves space in cable chains (drag chains).##### Audio and Broadcast SystemsYou can use this for professional audio. It works for microphones, speakers, and mixers. The shield stops the “hum” or “buzz” from power lines. It keeps your audio clean. It is great for paging systems and conference systems.##### CCTV and SecurityConnect your analog cameras. Use it for PTZ (Pan-Tilt-Zoom) dome cameras. The 4 cores allow you to send video, power, and control data in one cable (depending on the setup). It is reliable for video door phones and access control readers.##### Computers and Data BusesIt is perfect for RS-232 serial ports. It works for process control instrumentation. If you have a devicenet or profibus setup (with specific bus cables), this is a good general I/O cable.##### Dry and Damp EnvironmentsThe PVC jacket resists moisture. You can use it in basements, outdoor cabling ducts, or washing down areas (if not high-pressure jet). It handles oil and coolant splashes well in workshops.
Why choose this over a generic shielded cable?
You have choices. You can buy cheap generic cable. But you get what you pay for.##### Quality You Can TrustWe source high-purity copper. Cheap cables use recycled copper with high resistance. Our cable has a max conductor resistance of 79 Ohm/km. This means less voltage drop. Your equipment gets the power and signal it needs.##### Better ShieldingSome cheap cables have a foil shield only. Foil tears easily. Our braid is tough. It handles vibration. It provides better grounding. This is critical for safety and signal accuracy.##### StandardizationThe DIN 47100 color code means you always know which wire is which. Blue, Brown, Black, Grey. No guessing. This speeds up installation and reduces mistakes.##### Safety FirstThe cable is flame retardant. In a fire, safety is key. It does not emit toxic smoke easily. It meets EU CPR (Construction Products Regulation) standards.
