Product Introduction
The encoder cable series launched by Shanghai Suoqi Electric Wire & Cable Co., Ltd. is specifically designed for high-frequency signal transmission of precision devices such as servo motor encoders, sensors, and industrial cameras. It is widely used in CNC machine tools, industrial robots, automated production lines, and high-end equipment. Encoder signals are weak high-frequency signals, extremely sensitive to attenuation, crosstalk, and electromagnetic interference. Therefore, encoder cables are strictly designed in terms of shielding structure, impedance matching, and twisting process, and can be customized according to the number of cores, signal type, and installation environment.
Operating Condition Pain Point Analysis
The failure of encoder cables often manifests as inaccurate device positioning, frequent alarms, or even shutdowns, and the root causes are concentrated in four types of problems. First, electromagnetic interference coupling. The servo driver and motor cables generate a strong electromagnetic field through the inverter. If the encoder cable has an incomplete shielding structure or poor grounding, interference signals can couple into the signal line, causing pulse loss or position drift. Second, signal attenuation and crosstalk. Encoder signals have high frequency; if the cable conductor cross-section is too small or the dielectric properties of the insulation material are poor, signal attenuation can occur. If multiple pairs of signal lines are not shielded or isolated, crosstalk can form, affecting data integrity. Third, dynamic bending damage. Encoder cables move with the servo motor and drag chain, and repeated bending can cause the shield layer to break or the core wire to be damaged, resulting in signal interruption. Fourth, environmental corrosion. Oil and moisture entering the cable ends can corrode the conductors and shielding layer, leading to increased contact resistance and signal degradation.
Product Technology Analysis
From the perspective of raw material selection, the conductors of the encoder cables are made of high-purity oxygen-free copper wire to ensure low-loss signal transmission; the insulation layer is made of materials with low dielectric constant and low loss tangent to reduce high-frequency signal attenuation. Shielding is the core design of encoder cables: a double-layer shield structure of aluminum foil plus tinned copper wire braid is used, with a braid density of no less than 90%, providing multiple attenuation paths for high-frequency electromagnetic interference; some models use a dual structure of twisted pair shielding plus overall shielding, effectively suppressing crosstalk between signals in the twisted pairs. The sheath is made of flexible and wear-resistant materials, balancing dynamic bending life and oil resistance.
From the perspective of the cable manufacturing process, the signal pairs use a twisted pair process, with the twisting pitch precisely controlled to cancel interference between wire pairs; the twisted shielding layer uses a longitudinally wrapped aluminum foil with a drain wire structure to ensure shielding continuity and grounding reliability. During cabling, the wire pairs are arranged tightly, and the overall shielding layer fully covers them to avoid shielding interruptions. The jacket extrusion uses a low-speed precision process to control the uniformity of the outer diameter and wall thickness, reducing stress concentration during bending. Before leaving the factory, each batch undergoes tests for characteristic impedance, shielding continuity, and insulation resistance to ensure signal transmission quality.
