Description
Product overview
Standard AT203 linear scales outputting 2-phase square wave signals for NC machine tool feedback. Also useful for lab data capture, research instrumentation, automated QA, and engineering test stands.
Mitutoyo Linear Scales AT203 Series 539 is part of Mitutoyo Section H (Digimatic Scale Units and Linear Scales). Macroscopic Solutions supplies this product through a reviewed purchase or quote path so configuration, compatibility, shipping, freight, accessories, and support requirements can be confirmed before fulfillment.
Catalog reference: US-1005 H-24
Quote-only AT203 standard linear scale family from catalog page H-24. Official Mitutoyo catalog order numbers are preserved as variation SKUs. The catalog notes that the pulse signal unit is no longer needed because AT203 can connect directly to an NC machine tool.

Applications beyond production metrology
Common applications beyond routine manufacturing include research data capture, engineering test stands, university lab exercises, prototype measurement logging, environmental or materials-test fixtures, and industrial R&D workflows that need consistent measurement output or sensor integration.
Application notes are general examples for discovery and planning; confirm suitability, tolerances, fixtures, standards, and regulatory requirements for the specific measurement task.
