## Description

These are the same magnetic discs Pololu include with Pololu's [magnetic encoder pair kit for mini plastic gearmotors](https://core-electronics.com.au/magnetic-encoder-pair-kit-for-mini-plastic-gearmotors-12-cpr-2-7-18v.html) and [Romi encoder pair kit](https://core-electronics.com.au/romi-encoder-pair-kit-12-cpr-3-5-18v.html). 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 1.5mm-diameter motor shafts of Pololu's [mini plastic gearmotors](https://core-electronics.com.au/search/?q=mini+plastic+gearmotor) (**extended motor shaft versions only**). 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. For order quantities beyond what Pololu have in stock, please [contact us](https://core-electronics.com.au/contact) for lead time estimates.
