Gurley Model 9710 Modular Incremental Encoder Motion Type: Rotary Usage Grade: Protected Industrial Output: Incremental *Max Resolution: *w/external electronics Many Disc Sizes Friction Free Operation Vacuum-Compatible Option The Model 9710 is a versatile rotary incremental encoder. Its modular construction provides friction-free operation, and the wide selection of disc sizes affords the design engineer great flexibility. When used with the optional HR2B or HR2C interpolator, its optical resolution can be electronically increased and the output provided as quadrature square waves plus index from RS422 differential line drivers. For absolute positioning in a modular encoder, please refer to the 9710VA (rotary and linear) or 7700 (rotary in a compact package) datasheets Gurley Precision Instruments 514 Fulton Street Troy, NY 12180 U.S.A.

SPECIFICATIONS DIGITAL OUTPUT AND EXTENDED RESOLUTION The Model 9710 provides phototransistor output as unbuffered sinusoids. For digital output signals or extended resolution, our Models HR2B and HR2C electronics packages transmit quadrature square waves, gated index, and built-in "watchdog" selftest data via RS-422 differential line drivers. Output square waves are at 20 times the line count on the disc with the HR2B, or at 1, 2, 3, 4, 5, 8, 10, 12, 16 or 25 times the line count with the HR2C. Please refer to the HR2B/HR2C data sheet for full details. DISCS Gurley does not offer disc hubs...
