Sony SR74-072LSKKY Scale Unit

The Sony Magnescale SR74-072LSKKY is a slim magnetic linear scale unit in the SR74 family, engineered for high-precision position feedback on linear axes in CNC machines, presses, and automated tooling. Measuring 720 mm in length, this SR74 variant sits within Magnescale’s Slim SR74/SR75 line, which supports effective lengths from 70 mm up to 2,040 mm. It provides A/B incremental position signals and a reference point output via an EIA-422 interface, enabling reliable, controller-compatible feedback for servo systems. The scale offers a resolution of 0.05 μm peak-to-peak, allowing fine measurement steps essential for tight tolerances in machining and alignment tasks. Built for rugged manufacturing environments, the SR74’s slim, magnetically encoded scale reduces installation space requirements while maintaining durable operation on demanding equipment. Typical applications include CNC machine tools, precision measuring rigs, and automated assembly lines where accurate, repeatable linear positioning is required. The 720 mm SR74-072LSKKY designation identifies this fixed-length configuration within the SR74 family; when integrating, verify connector and lead-out details with the supplier to ensure compatibility with your control system.
