Magnetic Encoder Disc For 20D Mm Metal Gearmotors, Od 9.7 Mm, Id 2.0 Mm, 20 Cpr (Bulk) can be used with 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 a 9.7 mm diameter, and the hole through the center enables them to securely press-fit onto the 2mm-diameter motor shafts of 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.

Dimensions:

• Size: 9.7 mm outer diameter × 2 mm thick x 2.0 mm inner diameter
• Weight: 0.5 g
