Gurley Series 9480H Angle Encoder Motion Type: Rotary Usage Grade: Industrial Metrology Output: Incremental Max Resolution: 0.00010° (0.36 arcsec) Very High Resolution - Industrial Ruggedness The Series 9480H 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 9480H incorporates an internal ASIC (application-specific integrated circuit) to generate quadrature square waves up to 25 times the line count on the disc. Thus, the resolution (after 4X quadrature evaluation by the user) can be as fine as 0.36 arcsec (0.0001o, or 3,600,000 counts per revolution).
