Electro-Static Discharge (ESD) arises from friction and material separation, a common physical phenomenon. Humans can perceive static electricity starting at 3500V, yet for semiconductor precision electronic components, static electricity as low as 35V can cause irreversible permanent damage. Such ESD damage is highly concealed: it produces no sound and leaves no visible marks throughout production, even though internal component failure has already occurred. This triggers a chain of consequences: frequent equipment and system malfunctions, degraded product quality, higher scrap rates, increased maintenance costs, along with risks of customer complaints and claims.
Conclusion: ESD protection is not an optional upgrade for production lines handling sensitive components, but a fundamental manufacturing requirement.
Many production lines prioritize ESD control on workbenches, floors and work garments, yet frequently overlook cable chains — critical components undergoing continuous reciprocating motion within automated production lines. Per IEC specifications, cable chains fall under the category of “other surfaces (non-working surfaces)”, with a maximum allowable surface resistance of 10¹¹Ω.
| Material Category | Surface Resistance Range | Static Characteristics |
|---|---|---|
| Conductor | ＜10⁵Ω | Rapid charge dissipation with risk of sparking |
| Dissipative Semiconductor | 10⁵~10¹¹Ω | Enables controlled, gradual static discharge within the safe range |
| Insulator | ＞10¹¹Ω | Prone to charge accumulation, high risk of electrostatic breakdown |
DURAMOV® ESD Cable Chains adopt engineering plastic base material homogeneously blended with conductive modifiers. The entire link structure delivers stable anti-static performance, with surface resistance consistently below 10⁹Ω, falling within the safe static dissipation range. The products comply with IEC 61340-5-1 ESD protection standard. They steadily dissipate static charges generated by friction during reciprocating movement of cables, preventing damage to chips and precision electronic components caused by weak static electricity as low as 35V. Suitable for high-cleanliness, ESD-controlled automated working environments including semiconductors, display panels, lithium batteries and precision inspection.

Miniature motion units in confined spaces → C01E
Confined spaces requiring frequent cable replacement and maintenance → C21E / C31E
Medium-to-long travel, heavy load, multi-cable/hose bundles requiring separation → C02E
All E-series ESD cable chains feature bulk modified anti-static technology. Unlike coated anti-static cable chains, they will not lose anti-static capability under continuous friction and wear.
Conventional insulating cable chains have surface resistance above 10¹¹Ω. Static charges continuously accumulate during reciprocating motion, which easily leads to latent ESD breakdown of electronic components. DURAMOV®-E Series ESD cable chains achieve controlled static dissipation, eliminate electrostatic hazards originating from moving cables, protect precision electronic components and stabilize production yield.
