Linear Scales ST46-EZA Series 579-Compact Type

Series 579
Features
  • Includes an automatic adjusting function for the signal (EZA function) at the push of a button.
  • Detector head mounting and signal adjustment possible without oscilloscope or PC.
  • A setup indicator for checking signal strength is included.
  • I/F circuit integrated in connector shell reduces volume to 60% compared to conventional interface.
  • Self-diagnosis function with USB connectivity facilitates signal strength checking and parameter setup.
  • Glass and metal tape scales are available.
  • The thickness of the detector head is only 7.5 mm. The metal tape scale type has a mounting surface area of 12.5 by 9.325 mm, allowing use in applications where a space-saving design is important.
  • Drawings are available on request

point-to-point correction after ensuring the
metal tape is tensioned correctly.)
