Linear Scales ST24 Series 579-Standard Type

Series 579
  • Outputs 2-phase square and sinusoidal wave signals at 10μm pitch.
  • Has a thinner detector head (thickness 11mm).
  • The maximum effective measurement range of 3000mm enables use on large machines.
  • Two types available for each signal output specification.
  • LED function for indicating signal errors.
