Product description

iC-PX series devices are advanced optical, reflective, lensless encoder iCs featuring integrated HD Phased Array photosensors and a blue LED chip. They provide high signal quality with relaxed alignment tolerances. Digital A/B outputs with or without interpolation are available. Typical applications are incremental encoders for motor control.
