Mitutoyo 539-203-30 Linear Glass Scale 200mm IP53

Product Description

The MITUTOYO 539-203-30 is a linear glass scale from the AT113 series, designed for precision position feedback in machine tool and metrology applications. It delivers a resolution of 0.0004 inches and an accuracy of 0.0004 inches over a maximum measuring range of 8.66 inches (200mm). The scale body measures 8 inches in scale length and connects via a 9.84-inch cable. Rated IP53, it resists dust and low-pressure water spray, making it suitable for use in light industrial environments. Licensed metrology technicians and machine tool service professionals typically specify and install this component.

The 539-203-30 is applied in CNC machine tools, grinding machines, milling centers, and precision measurement equipment where closed-loop linear position feedback is required. The AT113 series glass scale format suits installations that demand high resolution in a compact, enclosed encoder housing. Operating temperature range is 0 to 45 degrees C, making it appropriate for temperature-controlled shop environments. Storage is rated from -20 to 70 degrees C.

• 9.84-inch cable length for flexible installation routing
• Operating temperature range of 0 to 45 degrees C

Compatibility

Designed as an OEM-style linear encoder scale for machine tool and precision metrology equipment requiring a glass-type linear scale with 0.0004-inch resolution in the AT113 series form factor.

Installation Notes

Installation is typically performed by a metrology technician or qualified machine tool service professional. Power down and de-energize the machine control before handling the scale or its cable connections. Mount the scale body and read head in strict parallel alignment per the equipment manufacturer's tolerances to avoid signal errors. Do not bend or stress the cable beyond the minimum bend radius specified by the equipment manufacturer.
