Magnetic Encoder Disc for 20D mm Metal Gearmotors, OD 9.7 mm, ID 2.0 mm, 20 CPR (Bulk)

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.

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.
