Mitutoyo 539-204-30 Linear Scale 250mm IP53 Glass

Product Description

The MITUTOYO 539-204-30 is an AT113 series glass linear scale designed for high-precision linear position measurement in machine tool and metrology applications. With a maximum measuring range of 250mm (10.63 inches) and a scale length of 426mm (16.77 inches), this unit delivers accuracy to 0.000400 inches and supports resolution down to 0.000005 inches (0.0001mm). The glass scale construction provides stable, thermally consistent readings. Installation is performed by metrology technicians and precision machine tool service personnel integrating position feedback into CNC or manual measurement systems.

The 539-204-30 is suited for use in precision machining environments where repeatable linear position data is required. It fits applications on milling machines, grinding machines, lathes, and coordinate measuring equipment. The IP53 ingress protection rating allows the scale to operate reliably in environments with limited exposure to dust and light liquid splash. Operating temperature range is 0 to 45 degrees C, making it appropriate for standard shop-floor conditions. The 3.00-meter (9.84-inch) cable provides connection reach to readout or controller units.

Installation Notes

Installation of linear scales should be performed by qualified metrology or machine tool service technicians. Power down and de-energize all equipment before mounting or connecting the scale. Proper alignment along the axis of travel is critical to measurement accuracy — follow the machine manufacturer mounting specifications. Avoid bending or kinking the cable and protect the scale body from direct impact during installation.
