These are the same magnetic discs Pololu include with Pololu's magnetic encoder pair kits. 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 Pololu's micro metal gearmotors with extended motor shafts. 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.
This bulk-packaged product is primarily intended for those wanting to integrate these encoder discs into their own systems in higher volumes, but the minimum quantity is set to five for those who want to just get a few as replacements or samples. Pololu will package these to order, and quantities shown in stock will be limited to 10 units. Pololu generally expect orders of up to a few hundred units to ship within a day. For larger orders, please contact us for lead time estimates.
