Catalog excerpts

Gurley Precision Instruments' Model A25S absolute optical encoder is unique with its advanced design featuring new encoder technology. The following features make it far more capable than competitive products: Faster and more accurate than either a resolver-based system, or any competitive optical encoder. Up to 17-bit resolution, the highest available in an encoder designed and priced for industrial applications. A rugged, compact transducer (2.5" dia x 1.25" long) makes the encoder easier to design into tight spaces. Fully accurate data at 600 rpm permits use at higher shaft speeds. Very high data update rate (1 MHz parallel, 100 kHz serial) allows the encoder to be used whenever "real time" data is needed, such as velocity feedback applications or wide-bandwidth positioning servos. Unique circuitry eliminates hysteresis deadband, so there's no error due to bi-directional operation. Natural binary bus-compatible output permits straightforward hardware and software interfacing. Optional interface card simplifies communication between the encoder and a computer. > Gurley Precision Instruments514 Fulton StreetTroy, NY 12180 U.S.A.(800) 759-1844, (518) 272-6300, fax (518) 274-0336, Online at www.gurley.com, e-mail: info@gurley.com ingenuity@work
