Your benefits

The small dimension allows manufacturers of low-power and minimal-power motors to considerably reduce the size of their motors

The stand-alone version is ideally suited as a master and path encoders

The SKS/SKM36 motor feedback systems have strongly penetrated the drive technology market

The consistent mechanical components in SEK/SEL37 allow for a high degree of flexibility with various encoder systems
