Is Signal Interference Ruining Your Work?
Do you hate it when your machines stop working because of bad cables? Does your DB37 serial connection lose data when near power lines or motors? We know how frustrating this is. You need a cable that stays strong in tough places. Our 37-core shielded cable fixes these problems. It blocks noise. It keeps signals clean. It works when you need it most.
Why This Cable Is Different
This is not a normal cable. It has two shields. One shield is aluminum foil. The other is a copper braid. This double shield stops EMI and RFI. EMI is electromagnetic interference. RFI is radio frequency interference. They come from motors, welders, and power lines. These noises break your data signals. Our cable stops them. The shields connect to ground. This sends noise away from your signals. If the shield is not grounded, it acts like an antenna. That makes interference worse. Our cable comes with a drain wire. This makes grounding easy. You get stable signals every time.
Technical Specs You Can Trust
Here are the real numbers for this cable:
- Cores: 37 cores. All are shielded together and individually.
- Wire Size: 0.14 square millimeters. This is 26 AWG. It is the best size for data and power mix.
- Conductor: Stranded copper. It is tin-plated. Tin stops rust. It makes soldering easy.
- Shielding: Double shield. Aluminum foil + copper braid. Coverage is over 90%.
- Jacket: PVC or LSZH. PVC is tough. LSZH is fire-safe. It does not make toxic smoke.
- Temperature: -40°C to +85°C. It works in freezers and hot factories.
- Voltage: 300V. It handles most control signals.
- Impedance: 50 ohms. It matches most serial devices.
- Flexibility: Bend radius is 10 times the cable diameter. It fits in tight spaces.
- Color: Black is standard. We can do gray, blue, or custom colors.
- Length: Any length. We cut it to your size.
Where to Use This Cable
This cable fits many places. You need it where there is noise or long runs.
Industrial Automation
Use it for CNC machines. Use it for PLCs. Use it for robot arms. Factories have big motors. They make a lot of noise. This cable keeps control signals safe. It stops the machine from making errors. It works with Siemens, Allen-Bradley, and Fanuc systems.
Medical Devices
Use it for MRI and CT scanners. These machines need clean data. A bad cable ruins the image. Our cable is safe for patients. It meets medical standards. It does not leak current.
Data Centers & Servers
Use it for serial consoles. Use it for rack management. Data centers have many cables. They get hot. Our cable resists heat. It stops crosstalk between cables.
Military & Aerospace
Use it for field radios. Use it for vehicle systems. These places are rough. The cable resists vibration and shock. It works in extreme cold and heat.
Audio & Video Broadcast
Use it for professional audio racks. Use it for lighting control. It stops hum and buzz in audio signals.
Easy to Install and Use
We make installation simple. You can order it with DB37 connectors. We put them on both ends. We use gold-plated pins. They do not rust. The connectors have screws. You can tighten them by hand. No special tools are needed. The jacket strips easily. It does not tear. You can use standard crimp tools. If you need to ground it, use the drain wire. Connect it to the chassis. This takes seconds. We can print labels on the cable. This helps you organize your wires.
Quality Control and Testing
We test every cable. We do not guess. We use professional testers.
- Continuity Test: We check all 37 wires. We make sure none are broken.
- Shield Test: We check the shield connection. It must have low resistance.
- Hi-Pot Test: We apply high voltage. We check for shorts.
- Burn-In: We test some cables at high heat. We make sure they last.
Our factory follows strict rules. We use ISO 9001 standards. We check the raw copper. We check the plastic. We check the final product. You get a cable that works for years.
