Differential Phase Shifters – DLO

Differential Phase Shifters – DLO

Phase Shifters In-Line


The DLO Series (In-line Differential Phase Shifters) allows accurate adjustment of the output shaft’s angular position, relative to the input shaft, while the machine is in motion, or even at rest. In-line Series combine a high quality planetary differential and an irreversible worm gear in one housing.

This arrangement allows infinite angular adjustment of the output shaft. See DR Series for right angle mounting solution.


  • Infinite angular adjustment
  • All possible orientation for mounting
  • Very low backlash: as low as 3 arc-minutes on demand
  • Standard range of different reduction ratio: 1 to 3
  • Optimized transmission error
