Datasheet: Inductive Encoder Chip PO1020
 
Description:
The Inductive Encoder Chip PO1020 measures position and speed of scales, discs and gears. The encoder consists of a silicon chip in a small package and is suitable for SMD-soldering on a Printed Circuit Board. The encoder chip contains a coil that generates a high-frequency magnetic field, 4 detection coils that measure the modulated magnetic field and all the analog and digital electronics to provide well-defined A quad B encoder signals. You can find a more detailed explanation of the inductive encoder working principle on our technology page.
