The Problem: Signal Loss and Noise in Critical Systems
You have a high-tech device. It needs to send data fast. It needs to be precise. But you keep seeing errors. The signal drops out. The image on the screen has static. You test the device, and it works fine in the lab. But in the real world, it fails. Why?Most cables are the weak link. They act like antennas. They pick up noise from motors, power lines, and other electronics. This noise corrupts your data. For high-frequency signals, even a tiny bit of interference is a disaster. You need a cable that blocks noise completely. You need a cable that does not lose signal strength over distance. You need a cable built for extreme precision. If you use cheap wire, you risk the whole system failing. That costs money and reputation.
The Solution: Sumitomo 1.5D-EXLLTA Imported from Japan
We bring you the solution directly from Japan. This is the Sumitomo 1.5D-EXLLTA single-core shielded cable. It is not just a wire. It is a precision tool for data transmission. Sumitomo Electric has over 120 years of history. They started making cables in 1897. They know how to build wires that last and perform.This specific cable is designed for the toughest jobs. It is a 0.2 sq mm multi-strand coaxial cable. It has dual screening. It maintains a strict 50-ohm impedance. This means your high-frequency signals travel clean and fast. There is no data loss. There is no ghosting. Just pure, reliable performance. Whether it is for a flying drone or a surgery robot, this cable handles the job.
Technical Specifications Breakdown
Let’s look at what makes this wire special. We use simple terms so you know exactly what you get.Conductor CoreThe inside of the cable is the conductor. It carries the electricity and data.
- Type: Multi-strand bare copper or tinned copper.
- Size: 0.2 square millimeters.
- Why it matters: Multi-strand means the wire is flexible. It bends easily without breaking. This is vital for moving parts like robotic arms or drone gimbals. Solid wire cracks when you move it. This wire moves with your machine.
InsulationThe conductor is covered in insulation. This keeps the electricity inside.
- Material: High-quality polymer (like PE or XLPE).
- Function: It stops the signal from leaking out. It also protects against heat and chemicals.
Shielding (The Most Important Part)This is where the 1.5D-EXLLTA shines. It has a “dual-screen” setup.
- First Layer: Aluminum foil or copper tape. It wraps 100% around the insulation. It blocks high-frequency noise.
- Second Layer: Tinned copper braid. It covers the foil. It blocks low-frequency magnetic interference.
- Result: You get a “Faraday cage” effect. No outside noise gets in. No inside signal gets out. This is critical for 50-ohm high-frequency lines.
Outer Jacket (Sheath)The final layer protects everything.
- Material: PVC, LSZH (Low Smoke Zero Halogen), or specialized TPE.
- Features: Flame retardant, oil resistant, and abrasion resistant.
- Diameter: The “1.5D” in the name often refers to the outer diameter (approx 1.5mm to 2.0mm range). It is thin and light. Perfect for weight-sensitive designs.
Electrical Performance
- Impedance: 50 Ohms ± tolerance. Matched perfectly for RF and data.
- Frequency Range: Designed for high frequencies (up to GHz range).
- Attenuation: Very low signal loss per meter.
Key Features and Benefits
Ultra-High Shielding Effectiveness
The dual-screen design is not just marketing. It works. In environments with heavy electromagnetic interference (EMI), like near heavy motors or radio towers, this cable keeps the signal clean. You do not need to worry about data corruption. The braid coverage is usually above 85% or even 95%. This ensures a solid ground connection and blocks noise effectively.
Flexibility and Durability
The 0.2 sq mm multi-strand core is incredibly flexible. You can route this cable through tight spaces in a control panel or inside a robotic joint. It has a long flex-life. It can bend thousands of times without the copper strands snapping. The outer jacket resists oil and chemicals. If you spill hydraulic fluid on it, the cable survives.
Precision Impedance Control
For high-speed data (like USB4 or Thunderbolt protocols), impedance matching is key. If the impedance jumps around, signals reflect back and cause errors. Sumitomo’s manufacturing precision keeps the impedance steady at 50 ohms. This ensures maximum power transfer and clear signal integrity. It supports stable transmission for radar systems and high-speed communication.
Lightweight Design
The “1.5D” series is known for being thin and light. In aerospace and drone manufacturing, every gram counts. This cable saves weight compared to standard shielded wires. It helps your device fly longer or use less battery.
Application Scenarios
Where should you use this specific Sumitomo cable?Aerospace and DronesDrones face vibration and space limits. They need lightweight cables that carry video and control signals without noise. This cable is perfect for connecting cameras, GPS modules, and flight controllers. It handles the vibration of takeoff and landing.Medical EquipmentHospitals need reliable equipment. Surgery assistance robots and ultrasonic diagnostic machines cannot afford signal errors. This cable is used inside medical devices where precision is a matter of life and death. It is also biocompatible and safe for use near patients.Industrial AutomationFactories are noisy places. Servo motors and welding machines create massive electromagnetic fields. Standard cables pick up this noise and cause machine errors. The 1.5D-EXLLTA cable ignores the noise. It keeps the factory running smoothly. It is great for encoder cables and sensor lines.High-Speed Data and TelecomFor 5G infrastructure, radar systems, and satellite communication, you need 50-ohm coaxial performance. This cable supports the high frequencies needed for modern data transmission. It is also used in test and measurement equipment.Automotive (EV and Hybrids)Electric vehicles have complex wiring. Sensors, infotainment, and battery management systems all need shielded lines. This cable resists the heat and electrical noise inside an electric car engine bay.
Why Choose Sumitomo Electric?
Sumitomo is not a new player. They have been around since the 1800s. They made Japan’s first high-voltage underground cable. They made the world’s longest submarine cable. They have a reputation for “monozukuri” (the art of making things).When you buy this cable, you are buying peace of mind. You know the copper is pure. You know the shielding is applied evenly. You know the quality control is strict. Sumitomo cables often meet JIS (Japanese Industrial Standards), UL (US standards), and RoHS (environmental safety).
Installation and Handling Tips
Installing this cable is easy if you follow basic rules.
- Cut Clean: Use a sharp wire cutter. A crushed end ruins the shield connection.
- Strip Carefully: Do not nick the conductor or the braid. If you cut the braid, the shield stops working.
- Connectors: Use proper 50-ohm connectors (like SMA, BNC, or custom board-to-board). Crimp them tightly.
- Bend Radius: Do not bend the cable too sharply. Keep the bend radius at least 5 times the cable diameter.
- Grounding: Connect the drain wire or braid to the metal chassis. This completes the shield. If you do not ground it, the shield does not work.
Frequently Asked Questions (FAQ)
Is this cable suitable for outdoor use?Yes, with the right jacket (like PE or UV-resistant PVC). It resists water and sunlight.Can I use this for audio?Technically yes, but it is overkill for audio. It is designed for high-frequency data (MHz/GHz), not audio frequencies (Hz/kHz). It will work, but it might be stiff and expensive for simple audio.What is the minimum order quantity?As an imported specialty item, we usually sell by the roll or meter. We can discuss small sample orders for testing.Does it come with connectors?We sell the cable by the meter or roll. You can crimp your own connectors, or we can help source compatible connectors.How fast can you ship?Since this is an import item, lead times depend on stock in our warehouse. Contact us for current stock levels. We ship worldwide via air or sea freight.
