Encoder Disk and Speed Sensor Pair HC-020K
HC-020K Speed Measurement Module Pair is a measurement module with high resolution and short response time. It can measure the engine speed with an encoder disk. The product includes two encoder disks and a photoelectric speed sensor. When measurements are made by connecting sensors to two wheels on the same plane, data can be compared and more precise results can be obtained.
