Are you tired of signal noise ruining your machine’s precision?
You run a factory or an automation business. You know that one bad cable can stop a whole production line. It is frustrating when your servo motor loses position. It is annoying when sensors give wrong readings because of electrical noise. You need a cable that works hard. It must bend a lot. It must resist oil and chemicals. And it must carry the signal clearly without any ghost data. We build this cable for you. It solves these headaches. It is not just a wire. It is a reliable part of your machine.
What makes this 4-core shielded cable special?
This is a 4-core 0.34 sq mm twisted pair shielded cable. It is also known as 22 AWG flexible cable. We design it for high-precision jobs. The core structure uses twisted pairs. Why do we twist the wires? It cancels out noise from the outside. Electric motors and VFDs create a lot of electromagnetic interference (EMI). Our twisting method stops this noise from hurting your signal.The “4-core” part means you have four separate paths for signals or power. This is perfect for incremental encoders. It works great for resolvers too. You can send power, ground, and two data signals (A and B channels) all in one jacket. This saves space in your control cabinet. It makes installation easy. You do not need to pull three different cables. One cable does the job.
Deep dive into the shield and jacket
Shielding is the most important part of a signal cable. Our cable uses a double-shield system for maximum protection.First, we wrap each pair in aluminum foil. This is a barrier against high-frequency noise. Second, we add a braided copper mesh over the whole cable. This mesh catches low-frequency interference. We connect this braid to a drain wire. You can ground the cable easily at one end. This stops ground loops. It keeps your data clean.The outer jacket is tough. We use flexible PVC or TPU. TPU is great for servo encoder cable uses. It resists oil, grease, and coolant. If your machine moves a lot, the cable needs to flex. Standard cables crack after a few thousand bends. Our cable is rated for high flex life. It works in drag chains. The minimum bending radius is small. You can route it in tight spaces without damage. The jacket is also flame-retardant. It meets safety standards for industrial panels.
Technical Specs You Can Trust
We make our cables to strict standards. Here are the real numbers for this 22 AWG flexible cable:
- Conductor Material: Bare copper or tinned copper (for anti-corrosion).
- Wire Gauge: 22 AWG (approx 0.34 mm² cross-section).
- Number of Cores: 4 cores (can be 2 pairs or 3 signal + 1 ground).
- Conductor Structure: Stranded copper (7/0.25mm or similar) for flexibility.
- Insulation: PVC or PE, color-coded (White, Brown, Green, Yellow, etc.).
- Shielding: Aluminum foil + Copper braid (coverage >85%).
- Outer Sheath: PVC, TPU, or TPE (Oil resistant).
- Rated Voltage: 300V (for control/signal) or up to 30V for data.
- Test Voltage: 2000V AC between cores.
- Insulation Resistance: > 1000 MΩ·km.
- Operating Temperature: -20°C to +80°C (TPU can go higher).
- Minimum Bend Radius: 6x to 10x outer diameter (flexible).
- Capacitance: Approx 100-120 pF/m (good for high-speed data).
- Impedance: Not strictly controlled like RF, but low resistance (approx 50-55 Ω/km).
These specs ensure the cable works in harsh environments. It handles the heat of a motor. It handles the cold of a freezer warehouse.
Where to use this cable?
You can use this wire in many places. It is a true multi-tasker.##### Servo Motors and RoboticsThis is the top use case. Connect the servo drive to the motor encoder. The 0.35 mm servo encoder cable variant is perfect here. It handles the high-resolution pulses. It ensures the motor knows exactly where it is. It prevents “following error” faults.##### Industrial AutomationUse it for PLC I/O connections. Link sensors to the controller. Use it for limit switches, proximity sensors, and photoelectric eyes. The shield stops the VFD noise from triggering false signals.##### Instrumentation and AudioIt works for low-level analog signals. Connect 4-20mA loop transmitters. Use it for microphone cables or audio interconnects if you need a rugged, shielded wire. The twisted pair keeps the hum away.##### Medical and Lab EquipmentBecause we can use medical-grade TPU, this cable fits diagnostic machines. It connects probes and sensors. It is easy to clean and resists disinfectants.##### CCTV and SecurityUse it for PTZ camera control. It carries video power and RS485 data for pan-tilt-zoom functions.
Why buy from us?

We cut it to size. We know the export market. We pack the coils safely. We use plastic film and strong cartons. The cables arrive without kinks or damage.Our pricing is fair. We cut out the middlemen. You get the factory price directly. We have fast lead times. Standard orders ship in days. Custom orders ship in weeks, not months.
How to order and get a sample
Buying cable online can be scary. You worry about the quality. You worry about the specs. We make it easy.First, look at the signal cable options on this page. Pick your jacket material (PVC or TPU). Tell us the length you need. We sell by the meter or by the spool (100m, 305m).Second, contact our sales team. Send us your drawing or a sample of your old cable. We can match it exactly. We can even print your logo on the jacket for big orders.Third, ask for a sample. We encourage you to test it before a big buy. Test the flexibility. Test the shield continuity. Put it next to a motor and see if the signal stays clean. We are confident you will like it.Ready to stop the noise and fix your wiring issues?Do not wait for the next machine breakdown.
