Is Your Signal Weak or Noisy? Here is the Fix.
Do you have a problem with your equipment? Maybe the signal is weak. Or maybe there is too much noise in the line. You see errors in your data. You see ghosting on your screens. This is frustrating. It wastes your time. It costs you money.Most cables are the problem. They are cheap. They use low-quality materials. They do not have good shielding. Noise gets in. The signal leaks out. The cable breaks when you bend it. You need a better solution. You need a cable that works every time. You need the Sumitomo 1.5D-EXLLTA.This is not a normal cable. It comes from Japan. Sumitomo Electric is a top brand. They have over 120 years of experience. They make cables for the toughest jobs. This cable is built for high speed. It is built for precision. It solves your noise problems. It fixes your signal loss. Let us look at why this cable is the best choice for your project.
What Makes the 1.5D-EXLLTA Special?
This cable is a single-core coaxial wire. It has a multi-strand structure. This means it is not stiff. It moves easily. It is great for tight spaces. The “0.2 sq mm” size is small. But it carries a lot of power and data.The most important part is the shielding. It uses a dual-screen design. This is a game changer. The first screen is a foil shield. It covers the core 100%. The second screen is a braided copper wire. This double layer stops noise. It keeps your signal clean. It is a 50-ohm cable. This is the standard for high-frequency work. It matches your equipment perfectly.
Dual-Screen Shielding: The Armor Against Noise
Noise is everywhere. Motors, lights, and other wires create it. They mess up your signal. This is called EMI (Electromagnetic Interference). You need to stop it. The 1.5D-EXLLTA has the answer.
The First Layer: Aluminum Foil
The inside layer is an aluminum foil. It wraps tightly around the core. It blocks high-frequency noise. It stops the signal from leaking out. It also stops outside noise from getting in.
The Second Layer: Copper Braid
The outside layer is a copper braid. It is woven like a net. It blocks low-frequency noise. It is very strong. It protects the foil inside. It also grounds the cable. This dual system is better than single-shield cables. It gives you -90dB or better shielding effectiveness. This is a huge number. It means almost zero noise gets through.
High-Frequency Performance: Fast and Stable
You need speed. This cable is made for high frequencies. It works up to the GHz range. It has low attenuation. Attenuation is the loss of signal over distance. With this cable, the loss is very low.For example, at 1 GHz, the loss is about 0.2 dB per meter. This is very good. Cheap cables might be 0.5 dB or more. With Sumitomo, you can run longer cables. You do not need amplifiers. You save money. You save space.The impedance is 50 ohms. It is very stable. It does not change with temperature or bending. This is vital for RF (Radio Frequency) signals. It is vital for medical imaging. It is vital for industrial sensors. If the impedance jumps, your system fails. This cable keeps it steady at 50 ohms.
The Build: Materials and Structure
Sumitomo uses top-tier materials. They do not cut corners. Let us look inside the cable.
The Conductor (Core)
The core is made of copper. It is not just solid wire. It is multi-strand. This means many tiny wires twisted together. This makes it flexible. It resists breaking from vibration. The size is 0.2 square millimeters. It is thin but strong. It carries the current well.
The Insulation
Around the core is the dielectric. This is the insulation. It uses special PE (Polyethylene) or XLPE. This material has low dielectric constant. This is key for speed. It keeps the signal fast. It also resists heat. It can handle up to 120 degrees Celsius. This is hot. Most cables fail at 80 degrees. This one keeps working.
The Jacket
The outside skin is the jacket. It is PVC or a special Halogen-Free material. It is tough. It resists oil. It resists chemicals. It does not crack easily. If you need a special color, Sumitomo can make it. They can add a luminous jacket. This glows in the dark. It helps you find the cable in the dark.

Where to Use This Cable? (Use Cases)
This cable fits many places. It is not just for one thing. It is versatile.
Medical Equipment
Hospitals use it. It is for MRI machines. It is for CT scanners. It is for ultrasound probes. These machines need clean signals. They cannot have noise. The dual shield keeps the images clear.
Industrial Automation
Factories use it. It connects sensors to PLCs. It works with servo motors. It handles encoder feedback. Factories have heavy motors. They create a lot of noise. This cable ignores the noise. It keeps the production line running.
Automotive and EVs
New cars are computers on wheels. They use high-speed data. This cable is for infotainment. It is for ADAS (driver assist). It is for battery management systems (BMS) in EVs. It is lightweight. The aluminum or copper braid is lighter than steel. It helps the car go further.
Audio and Broadcast
Studios use it. It is for SDI video cables. It is for high-end audio patch bays. It stops “hum” and “buzz” in the audio. It keeps the video signal sharp.
Aerospace and Defense
Planes and drones use it. Weight is critical. The cable is light. It is also strong. It handles vibration well. It is reliable in extreme conditions.
Why Buy Imported from Japan?
You might ask, “Why not buy local?” or “Why not buy from China?”The answer is consistency. Japanese manufacturing is strict. Sumitomo has a “Zero Defect” policy. Every meter of cable is tested. The tolerance is tight. The copper purity is high. The foaming of the insulation is even.With cheap cables, one batch is good. The next batch is bad. The diameter changes. The shielding is loose. This causes big problems for you. You have to re-calibrate your machines. You have to re-test your products.With Sumitomo 1.5D-EXLLTA, it is the same every time. You buy it once. It works. You buy it again. It works the same. This saves you headaches. It saves you QA costs. It is “Invisible Quality.” You do not see it, but you feel the difference.
Flexibility and Installation
Installing cable is hard work. You do not want a stiff cable. It breaks. It is hard to route. The 1.5D-EXLLTA is flexible. The multi-strand core bends easily. The jacket slides well.You can pull it through conduit. You can route it around corners. It has a minimum bend radius of about 10 times the diameter. This is very tight. You can use it in small devices. You can use it in robot arms that move all day. It will not crack. It will not break the conductor inside.
Customization Options
Sumitomo is not rigid. They can change things for you.
- Length: You need 50m? 100m? 500m? They can cut it.
- Connectors: You need a BNC on one end? An SMA? They can attach them. Or you can buy the cable and crimp them yourself.
- Jacket: You need a specific color? Blue for water lines? Red for power? They can do it. You need a fire-retardant jacket (LSZH)? They have it. You need a jacket that resists oil? They have special PUR jackets.
- Stripping: They can pre-strip the ends for you. This saves labor time in your factory.
Competitive Pricing and Value
Is it expensive? Yes, it costs more than a generic cable. But look at the Total Cost of Ownership (TCO).
- Less Scrap: Fewer failed tests.
- Less Downtime: Machines do not stop working.
- Less Warranty Claims: Your customers are happy.
- Longer Life: The cable lasts 10 years, not 1 year.
The price per meter is higher. The cost per successful unit is lower. This is smart buying. You are buying insurance for your product quality.
