Product Information

The optical encoder iC-PN2624 features monolithically integrated photosensors arranged in a phased-array.

A high transimpedance gain of typically 4 MΩ generates output signals of a few hundret millivolts already from illumination levels of 1 to 3 mW/cm2. In most cases no additional measures must be considered to filter for noise and interferences.

Analog nonius encoders are the typical application for iC-PN2624. Its 3-track scanning features a phased-array of multiple photosensors each per track, generating positive and negative going sine signals, as well as positive and negative going cosine signals. An excellent matching and common mode behavior of the differential signal paths is obtained by a paired amplifier design, reducing the needs for external signal calibration to an absolute minimum.

The spectral sensitivity range includes visible to near infrared light, with the maximum sensitivity being close to a wavelength of 680 nm. An output voltage of approximately 1 V is typical under low light conditions, for instance when iC-PN2624 is illuminated at only 1.5 mW/cm2 by an 740 nm LED.


• Absolute position encoders
