Ø 36 mm [EF36 K]
Ø 36 encoder series used in feedback systems on AC servomotor. It integrates a traditional incremental encoder and the optical generation of "Hall effect phases". Main characteristics are:
- Interchangeability with 15 size resolver that allow to save time and money because it is suffi cient to have only one predisposition for the retromotor.
- Easy mechanical assembly.
- Contained dimensions.
- Wide resolution range available.
