The ST422 Linear Scale has simultaneous output of 2-phase square wave signals and 2-phase sinusoidal wave with a measurement length of 3000mm.
Features & Benefits
The ultra-compact ST422 Linear Scale has an effective measurement length of 3000mm, making it ideal for use on large machines. It’s ultra-compact design allows the detector to be used in applications where space-saving is important.
- The maximum response speed is 5000mm/s. (When resolution is 1μm and the minimum edge interval is 125ns)
- Ultra-compact detector control unit allows use in applications where space-saving design is important
- The maximum effective measurement length of 3000mm enables use on large machines
- Simultaneous output of 2-phase square wave signals (maximum resolution: 0.2μm) and 2-phase sinusoidal wave signals (main signal: 40μm) is available
- LED display function for indicating signal errors
- Equipped with scale reference point output
