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.
