Sony GB-140A Electromagnetic Scale 59.8 Inch

Product Description

The SONY GB-140A is an electromagnetic linear scale designed for high-precision measurement applications. With a resolution of 0.00002 inches and a scale length of 59.8 inches, this unit delivers the fine positional feedback required in demanding metrology, machine tool, and precision manufacturing environments. The GB-140A uses electromagnetic sensing technology to produce reliable, repeatable position data across its full travel range. It is typically installed and serviced by precision equipment technicians, metrology specialists, and CNC machine maintenance professionals who require dependable sub-micron resolution in their measurement or motion control systems.

The GB-140A is suited for industrial and manufacturing environments where high-accuracy linear measurement is critical. Typical applications include CNC machining centers, coordinate measuring machines (CMM), grinding machines, and other precision positioning equipment that require continuous position feedback. The 59.8-inch scale length accommodates medium-to-large travel axes. This scale is appropriate for both new equipment builds and retrofit installations on existing precision machinery requiring measurement system upgrades.
