Is Your Cable Breaking in the Drag Chain? Stop the Downtime Now.
You know the feeling. Your production line is running fast. The robots are moving. The CNC machine is cutting. Then, suddenly, the system stops. You check the control panel. Error code. You trace the wire. Again. The cable inside the drag chain is cracked. The copper is exposed. The signal is gone.This happens because you are using standard cable. It is too stiff. It cannot handle the constant movement. Every time the machine moves back and forth, the wire fights against the chain. It gets pinched. It gets twisted. Over time, the insulation wears out. The shield breaks. Noise gets into your signal. Your sensors give wrong data. Your expensive machine sits idle while you wait for a replacement.You need a cable that moves like a snake, not a stick. You need a cable built for “high cycle” flexing. You need a cable that resists oil, cuts, and abrasion. We have the solution. It is the Japanese imported 24-core 0.3 square millimeter twisted pair shielded cable. It is not just a wire. It is a lifeline for your automated systems.
What Makes This Cable Special?
This is not a generic wire from the local market. This is a precision-engineered product designed for the toughest industrial environments. It combines Japanese material science with strict manufacturing standards. The result is a cable that lasts 10 times longer than standard PVC wires in moving applications.It uses a special mixed elastomer insulation. This material is not just soft. It is tough. It resists wear. It resists tearing. It handles temperature swings from -40°C to 105°C. Whether your factory is freezing cold or hot like an oven, this cable keeps working.The “0.3 square millimeter” size is the sweet spot. It is roughly 23AWG. It carries enough power for sensors and control signals. But it is thin enough to stay flexible. We use fine-stranded copper. This means the wire inside is made of many tiny threads, not one thick solid rod. This allows the cable to bend without breaking the metal inside.
Technical Specifications You Can Trust
We believe in transparency. You need to know exactly what you are buying. Here are the hard numbers for this 24-core shielded cable.
Conductor Details
The core of the cable is pure copper. We use tinned copper for corrosion resistance in humid areas.
- Cores: 24 Cores (12 Twisted Pairs)
- Cross-Section: 0.3 mm² (Approx. 23 AWG)
- Construction: Fine-stranded (Class 5 or 6 flexibility)
- Material: Bare Copper or Tinned Copper
- Stranding: 30/0.08 mm or similar fine stranding for max flexibility
Insulation and Twisting
We do not just run wires parallel. We twist them.
- Twisting Pitch: Short lay length. This reduces stress during bending.
- Insulation Material: Special PVC or PE (Polyethylene) blend.
- Insulation Color: Standard colors (Black, White, Red, Green, Blue, etc.) for easy identification.
- Pair Layout: 12 pairs twisted together. Each pair has a different twist rate to stop them from tangling.
Shielding Performance
Noise is the enemy of data. This cable fights noise with a double shield.
- Inner Shield: Aluminum Mylar foil. It covers 100% of the cores.
- Outer Shield: Tinned Copper Braid.
- Coverage: 85% to 95% coverage.
- Effectiveness: Stops EMI (Electromagnetic Interference) and RFI (Radio Frequency Interference). Your signals stay clean even near heavy motors.
Jacket and Outer Dimensions
The outside skin protects everything inside.
- Jacket Material: PVC, PUR (Polyurethane), or TPE.
- PVC is good for general use and cost-effective.
- PUR/TPE is best for oil resistance and heavy abrasion.
- Outer Diameter: Approx. 10.5 mm to 11.5 mm (depending on jacket thickness).
- Color: Black (standard), Orange, or customized.
- Print: White ink printing with core numbers and brand logo.
Mechanical Limits
- Minimum Bending Radius: 10x Outer Diameter (Dynamic). 5x Outer Diameter (Static).
- Tensile Strength: High resistance to pulling forces.
- Flex Life: Rated for over 5 million cycles (depending on bend radius).
- Oil/Chemical Resistance: Resistant to coolants, lubricants, and cutting oils.
Where Should You Use This Cable?
This cable is a workhorse. You will find it in places where movement happens. It is perfect for “cable chains” (also called drag chains or energy chains).
CNC Machines and Machining Centers
CNC machines move fast. The tool changer needs to move. The axis needs to move. Standard cables snap in these tight spaces. Our 24-core cable fits in small drag chains. It carries signals to the servo motors and feedback from the encoders. It resists the metal chips and coolant oil.
Industrial Robots and Robotic Arms
Robots have elbows and wrists. The cables inside the arm bend constantly. If the cable is stiff, the robot moves slower to protect the wire. With our high-flex cable, the robot can move at full speed. It increases your cycle time. It is also great for end-of-arm tooling (EOAT) sensors.
Automated Assembly Lines
Conveyor belts, pick-and-place machines, and packaging lines use drag chains. These chains move for 12 or 24 hours a day. A weak cable will fail in a month. Our Japanese imported cable lasts for years. It keeps your assembly line running without surprise stops.
Cranes and Hoists
In heavy industry, cranes move loads. The control cable for the crane hoist swings and twists. It needs a strong jacket. It needs a strong shield. Our cable handles the vibration and the weight. It is also flame retardant (CMR/CMP options available) for safety in public buildings.
Fire Protection and Security Systems
Because it is shielded and has a tough jacket, it works well for fire alarms and security cameras in harsh environments. It does not need a separate conduit pipe. You can run it exposed in cable trays or chains.
Why Choose “Japanese Imported” Quality?
You might ask, “Why pay for this specific cable?” The answer is in the details. Japanese cable manufacturers set the global standard for flexibility.They use a different mixing process for the PVC/PUR jacket. It stays soft in the cold. It does not get sticky in the heat. The stranding machine creates a “bunchy” stranding technique. This means the copper strands support each other when bent. They do not create micro-cracks.The shielding is applied tightly. In cheap cables, the braid is loose. It snags on the chain. It breaks. Our cable has a smooth jacket surface. It slides inside the chain links. It does not get stuck.Also, the electrical performance is better. The impedance is controlled. This means for high-speed data (like Ethernet or high-frequency servo drives), you get less signal loss. You get fewer errors. You get higher precision in your manufacturing.
Frequently Asked Questions About This Product
Can I use this for Ethernet or Cat5e?
This cable is primarily for control signals, power, and analog data. While it has excellent shielding, it is not rated as a Category cable (like Cat5e or Cat6) for high-speed LAN networks unless specifically certified. For standard industrial Ethernet (Profinet, EtherCAT) at lower speeds, it often works fine. For 1 Gigabit speeds, we recommend our specific Cat5e/Cat6 F/UTP or S/FTP drag chain cables.
Is the cable oil resistant?
Yes. If you choose the PUR (Polyurethane) or TPE jacket option, it is highly resistant to oils, greases, and coolants. If you choose standard PVC, it has some resistance but is not recommended for direct immersion in oil.
What is the minimum bending radius?
For dynamic movement (in a drag chain), do not bend it tighter than 10 times the outer diameter. For example, if the cable is 11mm thick, the bend radius should be at least 110mm (about 4.3 inches). If you bend it tighter, you will damage the conductor over time.
Do you have 24 cores in stock?
Yes. We keep 24-core, 12-core, 10-core, and 8-core configurations in stock. We can also customize the core count from 2 to 60 cores depending on your needs.
How do I ground the shield?
The shield must be grounded at one end only (usually the control panel side) to avoid ground loops. We include a drain wire (tinned copper) inside the cable to make grounding easy.
