These magnetic discs can be used with our micro metal gearmotors with extended motor shafts as part of a quadrature encoder system that offers 12 counts per revolution. They are 2 mm thick with an outer diameter of 7.65 mm and an inner diameter of 1.0 mm. Appropriate Hall Effect sensors, such as those in our , are required to complete the system. These discs are bulk-packaged in packs of 5.
These are the same magnetic discs we include with our magnetic encoder pair kits for micro metal gearmotors. The disc consists of six evenly spaced magnetic poles (three north-south pairs), which allows for an encoder system that offers 12 counts per revolution.
They are 2 mm thick with a 7.65 mm diameter, and the hole through the center enables them to securely press-fit onto the 1mm-diameter motor shafts of our micro metal gearmotors with extended motor shafts.
