Industrial high flexibility shielded network cables ensure stable signal transmission in frequently bent industrial dynamic environments through a dual mechanism of "physical structure anti-interference+material flexibility design". The core working principle is as follows:
1. Electromagnetic shielding principle (anti-interference core)
Using metal conductors to construct Faraday cage effect, blocking external electromagnetic interference (EMI/RFI) and preventing internal signal leakage.
Reflection and absorption: The inner aluminum foil shielding layer (with a thickness of about 0.025mm) utilizes the skin effect to efficiently reflect high-frequency electromagnetic waves (>1MHz); The outer copper woven mesh absorbs and cancels out low-frequency magnetic field interference (such as 50Hz power frequency and harmonics generated by frequency converters and motors) through eddy current effect.
Differential cancellation basis: The internal four sets of twisted pair cables generate in-phase noise on the two wires through precise calculation of the twisting distance, and the receiving end cancels it out through differential signal processing. The shielding layer further introduces residual interference into the ground.
Grounding discharge: The shielding layer must be reliably grounded at one or more points through an RJ45 metal casing or a dedicated grounding wire, guiding the induced current into the ground and forming a complete electromagnetic protection loop. ‌‌
2. High flexibility mechanical principle (dynamic durable core)
For frequent motion scenarios such as drag chains and robotic arms, traditional cable breakage problems are solved through material microstructure optimization.

Stranded conductor with multiple strands of fine wire: solid copper wire is discarded, and multiple strands of ultra-fine oxygen free copper wire (such as 7/0.19mm or finer) are tightly twisted. When bending, stress is dispersed to a single thin wire to avoid metal fatigue fracture caused by stress concentration, and can withstand tens of thousands or even millions of bending cycles.
Special insulation and sheath: The insulation layer and outer sheath are made of TPU (thermoplastic polyurethane) or modified TPEE material, which has high elastic memory function. These materials are resistant to oil, wear, and low temperatures, and can quickly recover to their original state after repeated stretching and compression, preventing impedance changes caused by misalignment of internal wire pairs. ‌‌
3. Double layered collaborative protective structure
Industrial grade products often use composite shielding structures (such as S/FTP or SF/UTP) to achieve full frequency protection.
Inner aluminum foil: tightly adheres to wire pairs, isolates crosstalk and high-frequency radiation between wire pairs.
Outer woven mesh: provides mechanical protection and shields low-frequency strong magnetic fields, with a weaving density typically ≥ 85% to ensure shielding effectiveness.
Independent Drain Line: Some high-end models include an independent grounding wire to ensure good electrical connectivity of the shielding layer during dynamic bending, avoiding grounding failure caused by shielding layer breakage. ‌‌
Key Tip: Shielding effectiveness is highly dependent on proper grounding. If the grounding potential difference between the two ends is too large, the shielding layer will instead become an interference source; In long-distance or complex industrial environments, it is necessary to strictly follow grounding regulations to ensure that the shielding layer is terminated 360 degrees
