Product Information

Back to top
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.

Blue-enhanced photosensors are adapted to the short wavelength of the embedded blue LED, and provide low-jitter outputs due to improved signal contrast. The unique assembly technology of the blue LED emitter and sensors results in low optical crosstalk.

Low-noise transimpedance amplifiers, arranged in a paired layout to ensure excellent channel matching, are used to convert the sensor signals into voltages of several hundred millivolts.

Precision comparators with hysteresis generate digital signals subsequently, either native or interpolated, which are evaluated and then output by ±4mA push-pull drivers.

Various operation modes are selectable via tri-level inputs SEL1 and SEL2: Digital A/B outputs with native (x1) or interpolated resolution (x2, x4, x8 or x16). The built-in LED power controller with its 20mA driver keeps the optical power constant regardless of aging effects, varying temperature or changes in working distance (iC to code disc).

iC-PX devices feature a low power consumption. They run at single-sided supplies of 4.5 V up to 5.5V.
