Stop Losing Signals and Wasting Time on Stiff Cables
You know the feeling. You are setting up a new production line or fixing a sensor network. Everything looks good on paper. But once you turn the power on, the data jumps around. The screen shows errors. The audio has a buzz. You check the connections, and the wires are tangled like spaghetti. You try to bend the cable to fit into a tight space, and it kinks. You force it, and the insulation cracks. Now you have a short circuit.This is not just annoying. It costs money. Every minute of downtime in a factory costs cash. Every returned product because of a loose connection hurts your reputation. You need a wire that works the first time. You need a wire that fits in small spaces without breaking. You need a wire that blocks noise so your data stays clean.We built this cable to solve those exact problems. It is not just a piece of copper. It is a solution for messy, noisy, and tight environments.
What Makes This 3-Core Shielded Cable Special?
This is a 3-core 0.13 sq mm shielded signal cable. Let’s break that down. “3-core” means it has three separate wires inside. This lets you send power, ground, and a signal all in one line. Or you can use it for balanced audio or differential data signals.The “0.13 sq mm” and “26 AWG” tell you the size. It is thin, but not too thin. It carries enough current for sensors and small electronics without being bulky. The “shielded” part is the most important. We wrap the inner wires in a foil shield and a copper braid. This acts like a guard. It stops outside noise—like from motors, fluorescent lights, or other machines—from messing up your signal.The “3.2mm outer diameter” is about the size of a standard pencil lead. It is slim. It fits into small cable chains and tight connectors. And the jacket? It is soft, durable, and gray. It does not get stiff in the cold. It resists oil and abrasion. You can drag it through machine parts, and it will not crack.
Technical Specs You Can Trust
We do not hide the details. Here is exactly what you get when you buy this cable. We make it strict so you know it works.
Conductor Details
The core of the cable is the metal. We use high-quality tin-plated copper. Why tin? It stops the copper from rusting. It also makes the wire easier to solder.
- Material: Tinned Copper (Bare copper is also an option)
- Gauge: 26 AWG (0.13 sq mm)
- Structure: 7 strands of 0.15mm wire twisted together. This makes the wire flexible. It does not snap if you bend it.
- Resistance: About 59.4 Ohms per kilometer at 20°C. This is low, so you do not lose voltage over long runs.
Insulation and Twisting
We do not just put wires side by side. We twist them. This cancels out noise.
- Insulation Material: HDPE (High-Density Polyethylene) or PVC. HDPE is great for high-speed data. PVC is flexible and tough.
- Colors: We use standard colors. White-Blue, White-Orange, White-Green, or just solid colors. You pick.
- Twist Rate: Precise twisting ensures consistent impedance.
Shielding Performance
Noise is the enemy. Our shield fights it.
- Shield Type: Aluminum Mylar Foil + Tinned Copper Braid.
- Coverage: 85% to 95% coverage. This means almost no noise gets in.
- Drain Wire: We include a tinned copper drain wire. It makes grounding the shield easy. You just connect one wire to the chassis.
Jacket and Outer Size
The outside protects the inside.
- Outer Diameter: 3.2mm ± 0.2mm. It is consistent. It fits 20mm conduit pipes easily.
- Jacket Material: Soft PVC or LSZH (Low Smoke Zero Halogen). LSZH is for places with strict fire rules, like tunnels or airports.
- Color: Gray (RAL 7001). It hides dirt and looks professional. Black is also available.
- Temperature: Works from -20°C to +80°C. It handles hot factory floors and cold freezers.
Electrical Limits
- Voltage: 300V / 500V. Safe for low-voltage control circuits.
- Capacitance: Less than 55 pF/inch. This keeps your signal fast and sharp.
- Impedance: Not strictly controlled like coax, but typically low for signal use.
Where Should You Use This Cable?
You can use this wire in many places. It is a workhorse. Here are the best spots for it.
Industrial Automation and PLCs
Factories use Programmable Logic Controllers (PLCs). These brains need to talk to sensors. A 3-core shielded cable is perfect for 4-20mA current loops. You send power on one core, ground on another, and the signal on the third. The shield stops the big motors from making the sensor readings jump. It fits into drag chains perfectly because it is only 3.2mm thick.
Audio and Video Systems
Do you need balanced audio lines? Use two cores for the signal (positive and negative) and one for the shield drain. The twisted pair rejects hum from power lines. It is great for connecting microphones to mixers or speakers to amps in noisy clubs or conference rooms.
Medical and Lab Equipment
Hospitals have a lot of electronic noise. MRI machines, X-rays, and pumps all create waves. Our cable protects sensitive data. The gray jacket looks clean in a lab. The soft jacket means it does not kink when nurses move equipment around. It is also compatible with ISO 13485 standards if you need medical-grade wire.
Security and CCTV
Security cameras need power and video. Sometimes they use RS485 for control. This cable can handle it. It is small enough to hide in walls or ceilings. The shield stops the video signal from getting “snowy” or distorted by nearby elevators or electric locks.
Automotive and Robotics
Cars and robots vibrate. Wires rub against metal. A standard wire would wear through in a week. Our PVC jacket is abrasion-resistant. The tinned copper resists battery acid and road salt. It is a great choice for wiring sensors inside a robotic arm or under the dashboard of a vehicle.
Why Buy From Us? We Know Cable
There are many cable sellers. But we are a factory. We make this wire ourselves.
We Control the Quality
We check the copper purity. We test the shielding coverage. We measure the outer diameter on every batch. If it says 3.2mm, it is 3.2mm. We do not cut corners. We have ISO 9001 and other certificates. You get a product that lasts.
We Can Customize It
Need a different color? We can do red, blue, or yellow. Need a longer length? We can cut it to 100m or 500m drums. Need a special connector on the end? We can crimp RJ45, DB9, or M8/M12 connectors for you. Just tell us what you need.
We Offer Competitive Prices
Because we are the source, you skip the middlemen. You get factory-direct pricing. For bulk orders, we can offer discounts. We also offer free samples so you can test the flexibility and quality before you place a big order.
