Mitutoyo: ST46-EZA Glass Linear Scales (579 Series)

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.
