The кабель энкодера is primarily used for connecting encoder signal transmission and feedback. It typically features a twisted-pair core wire design and includes a shielding layer to resist electromagnetic interference, ensuring the signal transmission capability and stability of the
With the widespread application of industrial automation, mobile encoder systems are also widely used in various devices or systems. The flex encoder cable that match them not only need to meet the requirements of encoder signal transmission feedback, but also need to be able to withstand the frequent reciprocating movement and bending of the drag chain components in the mobile encoder system. Therefore, кабель энкодера высокой гибкости that meet the needs of drag chain use are very important.
The material selection and structural design of shielded encoder cable that meet the requirements of drag chain operation are：
● Cable conductor: ultra-fine oxygen free bare copper wire multi strand precision twisted bundle, according to VDE 0295/CLASS 6 conductor standard;
● Cable insulation: High quality and high mechanical performance mixed elastic material/automotive material/PE/TPE and other materials are optional;
● Core wire structure: short pitch optimized twisted pair structure design;
● Filling: The filling material is made of Kevlar or hemp fiber;
● Shielding design: Aluminum foil Mylar/tin plated copper mesh with a coverage rate of over 85% is used as the shielding material design for the cable;
● Sheath design: High quality specially modified PVC, elastomer material T
For encoder cable, its shielding structure can generally be designed as the overall shielding structure of single-layer tinned copper network, the overall shielding structure of double-layer aluminum foil coating+tinned copper network, and the structural design of sub shielding (each pair of core wires are shielded separately)+overall shielding, which is used to deal with the encoder system under the environment of different transmission distances and different intensities of electromagnetic interference.
The design of elastic material sheath is mainly suitable for encoder systems in conventional indoor working environments. For complex and harsh indoor and outdoor encoder systems, PUR encoder cable recommended. This type of flexible encoder cable design has excellent performance such as high wear resistance, oil resistance, waterproofing, acid and alkali resistance, aging resistance, mechanical fatigue resistance, weather resistance, etc. It has better adaptability to encoder systems in more complex and harsh working environments
