Sony LH51SJ-1840 Dro System 2 Axis 0.0002 in Resolution

Product Description

The SONY LH51SJ-1840 is a 2-axis digital readout (DRO) system designed for precision measurement applications in machine shop and industrial environments. It delivers a resolution of 0.0002 inches and an accuracy of 10 micrometers, making it suitable for milling machines, lathes, grinding machines, and surface plates where tight dimensional tolerances are required. The scale length measures 42.1 inches, accommodating a wide range of travel on larger machine tools. Installation and commissioning are typically performed by qualified machine tool technicians or precision instrument specialists.

This DRO system is intended for use on manual machine tools in both production and toolroom settings. The 2-axis configuration covers standard X and Y axis measurement for milling and similar operations. With a 42.1-inch scale length, it suits larger bed mills or surface grinders where extended travel measurement is needed. The 0.0002-inch resolution supports close-tolerance work in metal fabrication, tool and die, and general machining operations.

Key Features

• 2-axis measurement for simultaneous X and Y axis readout
• 0.0002 inch resolution for fine, close-tolerance dimensional work
• 10 micrometer accuracy across the scale length
• 42.1 inch scale length accommodates extended machine tool travel
• Designed for milling machines, lathes, grinders, and surface plates

Compatibility

Designed as an OEM-style digital readout replacement or upgrade for manual machine tools requiring 2-axis linear measurement with a 42.1-inch scale length.

Installation Notes

Installation should be performed by a qualified machine tool technician familiar with linear encoder mounting and DRO wiring. Power down and lock out all machine tool circuits before mounting scales or routing cables. Follow the manufacturer's alignment instructions to ensure the read head maintains consistent parallelism with the scale throughout the full range of travel. Consult applicable facility electrical codes when routing signal and power wiring.
