Pololu Magnetic Encoder Disc for 20D mm Metal Gearmotors, OD 9.7 mm, ID 2.0 mm, 12 CPR (Bulk)

This magnetic encoder disc is designed for precision and compatibility with 20D mm metal gearmotors, featuring a 9.7 mm diameter and a 2 mm thickness. The disc's central hole allows for a secure press-fit onto 2 mm diameter motor shafts. It includes six magnetic poles arranged in three north-south pairs, facilitating an encoder system that delivers 12 counts per revolution.

Ideal for high-volume integration, these discs are perfect for those looking to incorporate reliable encoder solutions into their projects. Whether you're developing robotics, automation systems, or other motor-driven applications, these discs provide consistent performance and accuracy.

One of the standout benefits of using these magnetic discs is their ability to enhance the precision of motor control systems. They are particularly useful in applications where precise motor feedback is crucial, such as in robotic arms or precision machinery. The 12 counts per revolution offer a good balance between resolution and simplicity, making them suitable for a wide range of uses.

The compact size and easy installation of these encoder discs make them a versatile choice for both hobbyists and professionals. With a bulk package option, they are also an economical choice for large-scale projects or for keeping spares on hand.
