Incremental linear encoder 9717

opticalnon-contactdigital

Model 9717 incremental encoder gives direct measurement of linear position or speed without touching the reading head and the glass scale. Use of encoder with HR2B or HR2C interpolator offers electronically amplified optical resolution and the output is generated as quadrate square waves plus index from RS422 differential line drivers. The encoder gives unbuffered phototransistor output sinusoids. Quadrature square waves, gated index, and built-in "watchdog" self-test data is sent via RS-422 differential line drivers for generating digital output signals or increased resolution. Output square waves exist at 20 times the line count on HR2B scale or 1, 2, 3, 4, 5, 8, 10, 12, 16, or 25 times the line count on HR2C. 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 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.
