Description
Product overview
Compact ST46-EZA exposed linear scales with automatic signal adjustment and glass or metal tape scale options. Also useful for lab data capture, research instrumentation, automated QA, and engineering test stands.
Mitutoyo Linear Scales ST46-EZA Series 579 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-28
Quote-only ST46-EZA compact linear scale family from catalog page H-28. The page provides selectable configuration details rather than fixed order numbers, so child SKUs in this draft are internal quote configuration SKUs. Final Mitutoyo model/order details should be confirmed during quotation.
