Mitutoyo: ST422 Linear Scales (579 Series) Compact Type 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.
Detection method: Reflective photoelectric linear encoder Output signal: 2-phase sinusoidal signals, 2-phase square wave signals Main scale grating pitch: 40µm Signal output pitch: 40µm Effective range: 10 to 3000mm Accuracy (20°C)*1: ±1µm, ±2µm, ±3µm(/m) Resolution: 0.2µm/ 0.5µm/ 1µm/ 5µm (Selectable with internal switch) Scale reference point: Center point (10 to 75mm)/ 50mm pitch (100mm or more) Maximum response speed: 5000mm/s (varies depending on the setting) Minimum edge-to-edge interval: 125ns/ 250ns/ 500ns/ 1µs (selectable with internal switch) Operating temperature/ humidity range: 0 to 40°C, RH 20 to 80% (no condensation) Storage temperature/ humidity range: –20 to 60°C, RH 20 to 80% (no condensation) Head cable length: 1m
