DURAMOV® provides a full‑range plastic drag‑chain portfolio covering miniature, general‑purpose, high‑speed clean‑room and medium‑to‑large heavy‑duty grades, meeting cable guidance requirements from compact precision instruments to large‑scale automation equipment. C01, C11 and C21 belong to the miniature family with compact dimensions. C01 and C11 are non‑open one‑piece types; C21 supports double‑sided opening for confined installation spaces, widely adopted in small automation equipment, medical devices and precision testing instruments, with E‑suffix ESD anti‑static options available. C02 is the mainstream general‑purpose series, the most widely‑used model for industrial automation. It supports inner‑side, outer‑side and double‑sided opening modes for easy cabling and maintenance, with maximum operating speed of 20 m/s, suitable for most machine tools and standard automated production lines. C06 is dedicated for high‑speed clean‑room environments. Its short‑pitch elastic structure minimizes vibration and noise, with built‑in separators for clean‑room production, commonly used in semiconductor and optical equipment. C03 and reinforced heavy‑duty C03H are medium‑to‑large heavy‑duty drag‑chains with large inner cavities and customizable wide inner widths for large manipulators and big‑size processing machines. The suffix ‑E stands for ESD anti‑static modification with surface resistance below 10⁹ Ω for semiconductor, lithium‑battery manufacturing and explosion‑proof equipment. Series selection shall comprehensively consider travel stroke, running speed, total cable weight, anti‑static requirement and clean‑room specifications.
