MASSO contactless optical quadrature encoders have no moving parts, giving high accuracy and a very low failure rate.

Mount the encoder in front of a lathe spindle pulley to get full quadrature signals for multi-pass threading. No extra pulleys or timing belts are needed; it fixes in place with M3 screws.

Make an encoder disk label

1. Open the encoder disk generator and enter the pulley outer diameter (OD) and inner diameter (ID).
2. Print the label and count the black segments on the outer ring.
3. Enter that number in the PPR field at F1-Setup › Main Spindle .
