Magnetic Encoder Disc for Micro Metal Gearmotors, OD 7.65 mm, ID 1.0 mm, 12 CPR (Bulk)

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 magnetic encoder pair kit with top-entry connector for micro metal gearmotors, are required to complete the system. These discs are bulk-packaged and must be ordered in multiples of five.

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.

This diagram is also available as a downloadable PDF (74k pdf). A 3D model (16k step) is also available.

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. For order quantities beyond what we have in stock, please contact us for lead time estimates.
