Mitutoyo 539-205-30 Linear Scale 300mm Glass AT113

Product Description

The MITUTOYO 539-205-30 is a glass linear scale in the AT113 series, designed for high-precision position measurement in machine tool and metrology applications. It delivers a measuring range of 300mm (12 inches) with a resolution as fine as 0.000005 inches (0.0001mm) and a positional accuracy of 0.000400 inches. The scale is built with a slim spar profile, making it suitable for installations where clearance is limited. This type of scale is typically installed by metrology technicians or precision machine tool service personnel integrating encoder feedback into CNC equipment, CMMs, or digital readout systems.

The AT113 linear scale is used in precision measurement and motion control applications, both in shop-floor environments and controlled metrology labs. It is rated IP53 for protection against dust and light liquid ingress, supporting use in light industrial machine tool settings. Compatible counters include the KA Counter, KLD Counter, and PSU-200 readout units. The scale is suitable for residential metrology benches and commercial production-line inspection stations where repeatable, fine-resolution position feedback is required.

Key Features

• Glass scale construction provides thermal stability and long-term graduation accuracy
• Resolution range from 0.001 inches down to 0.000005 inches (0.01mm to 0.0001mm), selectable by counter
• IP53 ingress protection rating for dust and splash resistance in light machine tool environments
• Slim spar profile supports installation in tight-clearance applications
• 3-meter (9.84 inches) cable length accommodates standard DRO and counter wiring runs
• Operating temperature range of 0 to 45 degrees C with storage down to -20 degrees C

Compatibility

Designed for use with the KA Counter, KLD Counter, and PSU-200 readout units as stated by the manufacturer. Verify connector pinout and signal protocol compatibility with the target counter or DRO before installation.

Installation Notes

Installation is typically performed by a metrology technician or precision machine tool service professional familiar with linear encoder mounting and alignment. Power down all associated CNC or DRO equipment before mounting or connecting the scale. The scale body and read head must be aligned in parallel within the manufacturer-specified tolerance to ensure accurate output; consult the AT113 installation manual for alignment procedures. Avoid applying mechanical stress to the cable connector during routing.
