Original Press Release:
New Metrology-Grade Angle Encoder
TROY, NY -The Series 9480H from Gurley Precision Instruments is a robust metrology-grade optical encoder. It incorporates multiple read heads to eliminate many common sources of encoder errors, while its stainless steel construction greatly enhances resistance to thermal effects. 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 generates up to 7,200,000 counts/rev (after user's 4x quadrature decode), which is a resolution of 0.00005°, or 0.18 arc seconds. All electronics are inside the encoder and the accuracy is ±2.5 arc seconds.
The encoder is available with a 60 mm hollow shaft and incorporates an internal flexible shaft coupling. The 9480H is interchangeable with common competitive products.
Gurley is an ISO 9001-Certified company that offers rotary and linear optical encoders, as well as related accessories. You can see their wide selection of incremental and absolute encoders at www.gpi-encoders.com, or call 800-759-1844 for free applications assistance.
