Sony SL220-72 Electromagnetic Scale 76 Inch

Product Description

The SONY SL220-72 is an electromagnetic linear scale designed for high-precision measurement applications in industrial and manufacturing environments. With a resolution of 0.0005 inches and a scale length of 76 inches, this unit delivers fine positional feedback suitable for machine tool, metrology, and precision motion control setups. Accuracy is rated at 25+5L micrometers per 1,000 meters, providing consistent, repeatable readings across the full measurement range. Installation is typically performed by machine tool technicians or metrology specialists integrating the scale into CNC equipment, grinding machines, or coordinate measuring systems.

The SL220-72 is suited for applications requiring long-travel linear measurement in precision industrial settings. Its electromagnetic operating principle makes it a reliable choice for environments where optical scales may be susceptible to contamination from coolant, chips, or debris. The 76-inch scale length covers large-axis travel distances common in heavy machining centers, surface grinders, and similar equipment. Technicians integrating this scale into existing control systems should verify interface compatibility with the receiving readout or controller before installation.

Installation Notes

Installation of linear scales should be performed by a qualified machine tool technician or metrology specialist. Power down the host machine and any associated control systems completely before mounting or wiring the scale. Proper alignment of the scale body and read head is critical to measurement accuracy — follow the manufacturer alignment specifications for mounting tolerances. Reference applicable machine builder documentation and any local electrical codes when routing signal cables.
