Is Your Cable Too Stiff? Are You Losing Signal Data?
You know the struggle. You are installing a new sensor network in a factory. The wires are stiff and hard to bend. You force them into the conduit, and the insulation cracks. Or maybe you are working on a robot arm. The cable moves back and forth. After a few weeks, the wire breaks inside the jacket, and the machine stops. Worst of all, electrical noise from nearby motors messes up your data. Your sensor readings jump up and down for no reason. This costs you time and money. You need a wire that bends easily, blocks noise, and lasts a long time. You need a cable built for real-world movement and weak signals.
What Is This 5-Core Ultra-Soft RVV Cable?
This is not a standard stiff wire. This is a special 5-core 0.25mm² cable designed for sensitive jobs. It is an RVV type cable. That means it has a soft PVC jacket and flexible copper wires inside. We made it “ultra-soft” on purpose. It uses very thin copper strands twisted together. This lets the cable bend in tight spaces without damage.It is a sensor signal cable. It is also an instrument connection cable. We add shielding to stop outside noise. This shield is like a guard for your data. It keeps the electrical signals clean. You can use it for control signals, sensor data, and low-voltage power. It works perfectly in automation, robotics, and car electronics. It is flexible, strong, and ready for hard work.
Key Technical Specifications
Here are the hard numbers you need to know. This cable is built to meet high standards.
Conductor and Core Details
- Cores: 5 Cores (5 wires inside one jacket).
- Conductor Material: Bare copper or tinned copper strands. We use high-purity copper for best conductivity.
- Conductor Structure: Class 5 flexible stranding. This means many thin wires twisted together. It is not a single solid rod.
- Cross-Sectional Area: 0.25 square millimeters (mm²). This is about 24 AWG. It is small but perfect for signals.
- Resistance: The resistance is low. This ensures your signal travels far without losing power.
Insulation and Sheath
- Insulation Material: PVC (Polyvinyl Chloride). It is color-coded for easy identification.
- Sheath Material: PVC or Special Soft PVC/TPE. The outer jacket is very flexible and resistant to oil and water.
- Shielding: Aluminum foil shield + tinned copper drain wire. This is crucial for stopping EMI (Electromagnetic Interference).
- Armor: Unarmored. This keeps the cable light and easy to bend. If you need armor for underground use, ask us.
Electrical and Physical Properties
- Rated Voltage: 300V / 500V. It handles low to medium voltage well.
- Test Voltage: 2000V for 5 minutes. We test every batch to ensure safety.
- Operating Temperature: Fixed installation: -30°C to +70°C. Moving installation: -5°C to +70°C.
- Bending Radius: 6 times the cable outer diameter. It can bend very sharply.
- Flame Retardant: Meets IEC 60332-1 standards. It does not burn easily.
Where Should You Use This Cable?
This cable is a chameleon. It fits many jobs. But it shines where flexibility and signal purity matter.
Industrial Automation and Robotics
Factories are full of moving parts. Robot arms, conveyor belts, and CNC machines need cables that move millions of times. Standard wires crack. This ultra-soft cable survives. Use it for:
- Encoder connections on servo motors.
- Limit switches and proximity sensors.
- Control panels for PLC (Programmable Logic Controller) systems.
- Data transmission between machines.
Instrument and Sensor Networks
Sensors pick up tiny changes in temperature, pressure, or flow. These signals are weak. Noise can ruin them. This shielded cable protects the data. Use it for:
- Thermocouple and RTD extensions (with the right alloy).
- 4-20mA current loop transmitters.
- 0-10V analog signal sensors.
- Laboratory testing equipment.
- Building management systems (HVAC, fire alarms).
Automotive and Transportation
Cars have tight spaces and constant vibration. This cable is small and tough. It is great for:
- ADAS (Advanced Driver Assistance Systems) sensors.
- Infotainment system internal wiring.
- Door and window control modules.
- GPS and camera connections.
Audio, Video, and DIY
Because it is soft and easy to strip, hobbyists love it.
- Internal wiring for 3D printers.
- Stage lighting control (DMX).
- Custom electronics projects.
- Security camera (CCTV) installations in tight corners.
Why Is “Ultra-Soft” Better for You?
You might ask, “Why not just use a cheap standard wire?” Here is the truth.
Easier Installation
Stiff wires fight you. You need more force to pull them. You need bigger bends. This soft cable glides through pipes. It fits into small cable chains (drag chains). Your electricians finish the job faster. You save on labor costs.
Longer Lifespan
Stiff wires break from vibration. The copper fatigues. Our flexible stranding distributes the stress. The cable can handle 10 million bend cycles or more. It stays working when stiff wires fail. This means less downtime for your machines.
Better Signal Quality
We use twisted pairs inside the shield. This cancels out noise from nearby power cables. If you run this cable next to a 110V power line, your signal stays clean. Cheap unshielded cables act like antennas. They pick up buzz and static. This causes errors in your control system.
Safety First
The PVC jacket is flame retardant. It resists oil and sunlight. It is safe for indoor and outdoor use (if protected from direct sun long-term). It meets CE and CCC safety standards. You get a product that is safe for your workers and equipment.
Frequently Asked Questions About This Cable
Can I use this for power and signals in the same cable?
Yes, but be careful. This cable is rated for low power (like 24V DC or 110V AC). Do not use it for high-power mains electricity (like 220V AC for a heater). It is designed for control circuits and instrumentation.
Is the shielding 100% coverage?
We use an aluminum foil shield with a drain wire. It provides excellent coverage (around 85-95%) for high-frequency noise. For extreme noise environments, we can double-shield it.
How do I strip the jacket?
It is very easy. Because the PVC is soft, a standard wire stripper works perfectly. You will not damage the copper strands easily.
What colors are available?
The standard jacket color is Black (RAL 9005) or Grey (RAL 7001). We can do white or orange for specific runs, but black is best for hiding dirt in industrial settings. The inner cores are colored (Brown, Blue, Black, White/Blue, Green/Yellow) for easy ID.
What is the minimum order quantity?
We are a factory. We support small samples for testing. We also support bulk orders by the kilometer. We can put it in 100m or 500m drums.
