Theyprovide high signal quality with relaxed alignment tolerances.Differential digital ABZ outputs with or without interpolation or analogSIN/COS outputs with index are available. Typical applications areincremental encoders for motor control.Blue-enhanced photosensors are adapted to the short wavelength of theembedded blue LED, and provide low-jitter outputs due to improved signalcontrast. The unique assembly technology of the blue LED emitter andsensors results in low optical crosstalk.Applicationss Incremental encoderss Miniature motors and actuatorss X-Y and linear stagess Factory automation robotss Consumer robotsBlock DiagramiC-PRCONDITIONING CONVERSIONCONVERSIONOSCILLATOREVALUATIONPOWER-ONINDEX/DIGTRI-LEVELBLUE LEDCONTROLCONTROLDRIVERSSINE/DIGOUTPUTPOWERSIGNALDNCOSDPCOSSIN² COS²RESETLOGICDNSINDPSINMODETESTDPZDNZTM1GNDDSEL2TM2TMONZGNDAPAVZPBNAVCCSEL1TZVDDEDCPZNBANABYPDIG ---iC-PR Series
