Gurley Series 8460 Angle Encoder Motion Type: Rotary Usage Grade: Industrial Metrology Output: Incremental Max Resolution: 0.000078° (0.28 arcsec) Very High Resolution - Industrial Ruggedness The Series 8460 is a robust metrology-grade encoder that is equally well-suited for industrial applications. It incorporates four reading heads to eliminate many common sources of encoder errors, while its stainless steel construction greatly enhances resistance to shock and vibration. It is designed for very precise positioning of rotary tables on machine tools, coordinate measuring machines, dividing apparatus, antennas, test equipment and similar devices. The 8460 incorporates an internal ASIC (application-specific integrated circuit) to generate quadrature square waves up to 50 times the line count on the disc. The 8460 is available in both shafted and hollow shaft versions, and is interchangeable with common competitive products. Gurley Precision Instruments 514 Fulton Street Troy, NY 12180 U.S.A.
