A precision optical or magnetic disk used in rotary encoders to convert angular position into digital signals for motion control systems.
A code disk, also known as a scale or encoder disk, is a critical component in rotary encoders that features precisely patterned tracks (optical, magnetic, or capacitive) on its surface. As it rotates with a shaft, these patterns are read by sensors to generate electrical pulses corresponding to angular displacement, enabling accurate position, speed, and direction measurement in automated machinery.

不是客户评论，也不是实时热度。以下维度用于前期 RFQ 准备和供应商评估。
这些分值是采购评估维度示例，不代表真实客户评分、具体国家买家反馈或实时询盘。
Incremental disks have uniform patterns that generate pulses for relative position measurement, requiring a reference point. Absolute disks have unique patterns for each position, providing immediate position data without homing.
Temperature changes can cause material expansion/contraction affecting accuracy. Contamination (dust, oil) can obscure optical patterns or interfere with magnetic fields. Vibration may cause reading errors or mechanical damage.
Regular cleaning of optical surfaces with appropriate solvents, inspection for physical damage or wear, verification of mounting integrity, and periodic calibration checks against reference standards.
