This convenient pair of laser engraved wheel encoder disks can be mounted to any robotic wheel and/or servo horn.

The disks feature a bolt pattern that matches both Futaba and Hitec servo horns.

This pair of encoder disks feature a 30 spoke pattern, have a 1.50" outside diameter, and are 1/16" thick.

These disks are manufactured out of high quality laminated color plastic to offer a very crisp black to white transition. This enables a wheel encoder sensor to easily see the transitions. They are also much easier to use than having to glue printed out paper encoder patterns to a rigid disk.
