H-25HLinear ScalesDesigned to capture positional coordinates from slides on machine tools and precision instruments including semiconductor production equipmentMitutoyo operates a policy of continuous improvement that aims to provide the customer with the benet of the latest technological advances.Therefore the company reserves the right to change any or all aspects of any product specication without notice.•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.Linear Scales ST46-EZASERIES 579 — Compact TypeSPECIFICATIONSRefer to the ST46-EZA Series (Catalog No.E13008) for more details.Glass Scale TypeMetal Tape Scale Type•Double-end mounting design•Double-sided tape mounting designModelST46-EZADetection methodReflective photoelectlic linear encoderScale type GlassMetal tapeMain scale grating pitch20µmOutput signalType B: 2-phase square wave signals, reference point pulse, external reset input.Type C: 2-phase square wave signals, reference point pulse, 2-phase sinusoidal signals.Effective range10 to 3000mmAccuracy (20°C)Effective range 10 to 300mm: ±1μm Effective range 350 to 500mm: ±2μm Effective range 600 to 1000mm: ±3μmEffective range 1100 to 3000mm: ±3μm/mEffective range 10 to 1000mm: ±5μm Effective range 1100 to 3000mm: ±5μm/m(The above accuracy applies to individual scales.
