Linear Scales ST36 Series 579-High Accuracy Type

Series 579
  • Outputs two-phase sinusoidal wave signal, two-phase pulse signal, and 1Vp-p at 4μm pitch.
  • High accuracy type, 0.5μm class (effective range up to 300mm)
  • Has a thinner detector head (thickness 11.5mm).
  • The maximum effective measurement range of 3000mm enables use on large machines.
  • 4 different types available for each signal output specification.
  • LED display function for indicating signal errors.
  • Along with the output specifications of 2-phase sinusoidal wave and 2-phase square wave, the output specification of 1Vp-p wave is also available.
