Sony SL220-86 Electromagnetic Scale 90 Inch

Product Description

The SONY SL220-86 is an electromagnetic linear scale designed for high-precision measurement applications in industrial and metrology environments. With a resolution of 0.0005 inches and a scale length of 90 inches, it delivers fine positional feedback suited to CNC machinery, coordinate measuring machines, precision grinding equipment, and similar precision motion systems. Accuracy is rated at 25+5L per 1,000 meters, indicating a high-grade linear measurement standard. Installation is typically performed by qualified metrology or machine tool technicians integrating the scale into a digital readout or motion controller system.

The SL220-86 is intended for precision industrial applications where accurate linear position feedback is critical. Its 90-inch scale length accommodates large-travel axes found on milling machines, lathes, grinding machines, and other precision machine tools used in manufacturing and quality control settings. The electromagnetic operating principle provides reliable feedback in environments where optical scales may be challenged by coolant, chips, or contamination typical of machine shop conditions.

Compatibility

Designed as an OEM-style linear scale for integration into precision machine tools and measurement systems requiring electromagnetic linear position feedback over a 90-inch travel range.

Installation Notes

Installation should be performed by qualified machine tool or metrology technicians familiar with linear scale mounting and alignment procedures. Power down all associated equipment before mounting or wiring the scale. Proper alignment along the axis of travel is critical to achieving rated accuracy. Consult the machine manufacturer and applicable metrology standards for mounting clearances and signal interface requirements.
