Let us know if you're interested in a particular resolution or disk diameter not available yet.

Notes:
1) One of the encoder disks and the SSN2 sensor will do the exact same job as the expensive two channel HEDS-5500 encoder.
2)The encoder disks come in square sheets, so they'll still need to be cut around, and if needed, a center hole will have to be drilled. This will have to be done by the user, which is not hard to do.
