The Model 9717 is a high-resolution incremental encoder that offers direct measurement of linear position or speed without contact between the reading head and the glass scale.When used with the optional DIGITAL OUTPUTSSCALES 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.The Model 9717 provides unbuffered phototransistor output 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" self-test data via RS-422 differential line drivers. Output square waves are at 20 times the line count on the scale 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.The following scales are available from existing masters. Additional standard scales may be added periodically; special scales can always be made on a custom basis. > Scale pitchMax. lengthCross-sectionMax. res.with HR2B *Max. res.with HR2C * 40 m3.2 m1.125Ք x 0.1890.5 Եm1.0 m 0.002 in125 in1.125Ք x 0.1890.00025 in0.0005 in * After 4X quadrature decode in user's electronics 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
