WebFeb 2, 2024 · The greater the number of steps / lines the finer the resolution. This is determined by the number of digital sensors and or lines on the optical plate the sensors use. This is fixed. If you want more increments you have to get a better encoder. The analog sin/cos encoder uses 3 coils (one driver coil and 2 sensing coils). WebHow does an optical encoder work? Just like magnetic and inductive encoders, optical encoders work with a ruler. With optical technology, the ruler consists of a pattern of reflectors, or the light-sensitive layer. If an object moves, the encoder is moved across the ruler. These rulers are available in both straight and round versions. phil keaggy carefree https://departmentfortyfour.com
