These magnetic discs can be used with our 20D mm metal gearmotors (extended motor shaft versions only) as part of a quadrature encoder system that offers 20 counts per revolution. They are 2 mm thick with an outer diameter of 9.7 mm and an inner diameter of 2.0 mm. Appropriate Hall Effect sensors, such as those in our magnetic encoder pair kit for 20D mm gearmotors, are required to complete the system. These discs are bulk-packaged and must be ordered in packs of five.

These are the same magnetic discs we include with our magnetic encoder pair kit for 20D mm gearmotors. They are 2 mm thick with a 9.7 mm diameter, and the hole through the center enables them to securely press-fit onto the 2mm-diameter motor shafts of our 20D mm metal gearmotors (extended motor shaft versions only). The disc consists of ten evenly spaced magnetic poles (five north-south pairs), which allows for an encoder system that offers 20 counts per revolution. A 12 CPR version of this disc is also available.
