Influence of the optical, mechanical and electrical parts of the encoder on accuracy

First, the encoder optical part of the impact on the accuracy of 1, the optical code plate: the main thing is the motherboard accuracy, the number of engraved lines per revolution, engraved line accuracy, engraved line width consistency, edge refinement and so on. 2、Optical emission source: light parallelism and consistency, light attenuation. 3、Light receiving unit: reading angle, reading response. Drawstring displacement sensor fully combines the advantages of the angle sensor and linear displacement sensor, become a small installation size, compact structure, measuring stroke, high precision sensor, stroke from a few hundred millimeters to more than ten meters. 4, the optical system after use: pollution, attenuation. Second, the mechanical part of the encoder on the accuracy of the impact 1, the shaft processing accuracy and installation accuracy. 2, bearing accuracy and structural accuracy. Binary encoder is a pre-specified method of text, numbers or other objects coded into binary digital, or information, data into a prescribed binary electrical pulse signal. 3, code disk mounted...
