Are you tired of signal noise ruining your industrial equipment? Do your sensors keep failing because of interference from heavy machines? You spend a lot of money on high-tech control systems. But if your cables are bad, the whole system fails. Signal loss, data errors, and system downtime cost you time and profit. You need a cable that blocks noise and lasts a long time. You need a cable that works perfectly in tough environments. This is not just a wire. It is a solution for your signal problems. We bring you the HITACHI Japan 20 AWG twisted-pair shielded cable. It is built for stability, durability, and peace of mind.
Why Signal Noise Is Your Biggest Enemy
Imagine a busy factory floor. Big motors run. Welding sparks fly. Radio waves fill the air. This is electromagnetic interference (EMI). It is everywhere. If your signal cable does not have good protection, this noise gets into your data lines. Your sensors send wrong signals. Your PLC stops working. You have to stop production to find the error. This is a nightmare for any engineer or maintenance manager. Standard unshielded cables cannot handle this. They act like antennas. They pick up all the bad signals. You need a shield. You need a barrier between your clean signal and the dirty environment. This cable has that barrier. It uses a braided shield to stop noise. It keeps your signals clean and your machines running smooth.
Technical Specifications That Matter
We know you need exact numbers for your project. Here are the hard facts about this cable. It meets strict industrial standards. You can trust these numbers for your design.
- Brand: HITACHI (Japan Quality)
- Conductor: 2 Cores (2-pair)
- Wire Gauge: 20 AWG (Approx. 0.5 sq mm)
- Stranding: Stranded Tinned Copper (Flexible and anti-rust)
- Insulation: PVC (Polyvinyl Chloride)
- Shielding: Braided Shield (Tinned Copper Drain Wire)
- Jacket: PVC, Grey or Black (Sunlight and Oil Resistant)
- Voltage Rating: 300V Max
- Temperature Range: -20°C to 105°C
- Certifications: RoHS, UL Style 2464 Compliant
This is not cheap wire. This is industrial-grade cable. The 20 AWG size is perfect for control signals. It is thick enough to carry power to a sensor but thin enough to be flexible. The tinned copper means it will not corrode in humid or wet places. The PVC jacket protects against oil and chemicals. If you are looking for a 2 core 0.5 sq mm shielded cable for a security system or an intercom, this is the right choice.
How The Twisted Pair Design Works
You might ask, why is it “twisted”? This is not just for looks. The twisting is a smart engineering trick. When two wires run parallel, they create a loop. Magnetic fields pass through this loop and create noise. By twisting the wires, the loop orientation changes constantly. The noise picked up in one twist is cancelled out by the next twist. It is called differential signaling. It is very effective.But twisting alone is not enough for heavy industry. That is why we add the shield. The braid surrounds the twisted wires. It acts like a cage. It catches any outside noise and sends it to the ground. The drain wire makes grounding easy. You connect it once, and the shield works. This combination of twisting and shielding gives you the best protection. It ensures low capacitance and high signal integrity. For long cable runs, this is critical. You do not want your signal to fade away before it reaches the controller. This cable keeps the signal strong over long distances.
Real-World Applications: Where To Use It
This cable is very versatile. We sell it to many different industries. Here are the top ways our customers use it. You might see your project in this list.
Industrial Automation and PLCs
Factories use Programmable Logic Controllers (PLCs) to run assembly lines. These systems need reliable data cables. If the cable fails, the line stops. Our customers use this 20 AWG cable for I/O modules, proximity sensors, and servo motor feedback. It handles the vibration and electrical noise of the factory floor.
Security and CCTV Systems
Security cameras need power and video signal. Sometimes they need audio too. This 2-core cable is great for analog CCTV. It is also perfect for access control systems. Electric door locks and card readers use low voltage signals. This cable protects those signals from being jammed or interfered with. It ensures the door opens when it should.
Audio and Intercom Systems
Have you ever heard a buzz in a speaker or intercom? That is ground loop noise. The braided shield in this cable stops that buzz. It is ideal for public address (PA) systems, office intercoms, and background music systems. The twisted pair keeps the audio clear. The flexible jacket makes it easy to route through walls and ceilings.
Medical and Lab Equipment
Hospitals have a lot of sensitive electronic equipment. They need cables that do not emit noise and are easy to clean. The PVC jacket is resistant to cleaning agents. The low smoke zero halogen (LSZH) options are available for indoor safety. While this specific model is PVC, it meets the flammability standards for many commercial buildings.

Check our price list. You will see that we beat the big brands on cost but match them on quality.
Installation Tips for Best Performance
To get the most out of this cable, follow these simple rules. Good installation saves you headaches later.
- Ground the Shield: This is the most important step. Connect the drain wire to a good earth ground at one end only. Usually, this is the control panel end. If you ground both ends, you can create a ground loop. This causes noise. So, ground one end.
- Avoid Sharp Bends: All cables have a bend radius. Do not bend this cable sharper than 10 times its diameter. If you kink it, the impedance changes. This reflects the signal and causes errors.
- Separate from Power Lines: Do not run this signal cable right next to a high-voltage power cable. Keep at least 6 inches of distance. If you must cross them, cross at a 90-degree angle. This minimizes induction.
- Use Proper Connectors: Use shielded connectors. If you use a cheap metal connector that does not cover the whole jacket, the shield is broken. Make sure the connector clamps the shield properly.
Frequently Asked Questions
Is this cable suitable for outdoor use?Yes, the PVC jacket is sunlight resistant. It can handle UV rays. However, for direct burial or extreme weather, we recommend a PE (Polyethylene) jacket version. Contact us for details.Can I use this for audio speakers?It is not designed for high-power speaker lines (like 110V). It is for low-voltage signals (under 30V). It is perfect for microphone lines or intercom audio, but not for driving large speaker cones.What is the minimum order quantity?We are flexible. We can ship samples. For bulk production, the price breaks start at 1,000 meters. The more you buy, the cheaper it gets. Check our FOB price list for current rates.Does it come with a warranty?Yes.
