Sony SL220-142 Electromagnetic Scale 146 Inch

Product Description

The SONY SL220-142 is an electromagnetic linear scale designed for precision measurement applications in machine tool, metrology, and industrial automation environments. With a resolution of 0.0005 inches and a scale length of 146 inches, this unit delivers high-accuracy positional feedback over an extended travel range. Accuracy is rated at 25+5L micrometers per 1,000 meters of travel, making it suitable for demanding CNC and coordinate measurement tasks. Installation and integration are typically handled by machine tool technicians or industrial maintenance electricians familiar with linear encoder systems.

This electromagnetic scale is used in applications requiring long-range, fine-resolution linear position measurement. Typical installations include large-format CNC machining centers, grinding machines, milling machines, and coordinate measuring machines (CMM) where consistent accuracy across extended axes is required. The 146-inch scale length accommodates large-bed machines common in heavy manufacturing and precision fabrication environments.

Installation Notes

Installation of linear encoder scales should be performed by qualified machine tool technicians or industrial electricians familiar with encoder alignment procedures. Power down all machine axes and related control systems before mounting or wiring the scale. Proper alignment between the scale body and read head is critical to maintaining rated accuracy across the full travel length. Consult the machine builder documentation and applicable electrical codes for signal wiring and grounding requirements.
