E909.02 Datasheet PDF - ELMOS Semiconductor AG

DESCRIPTION
The IC is an optical sensor which provides a non-mechanical detection of movements. The EEPROM allows a free confi guration of the sensor-structure and the detection algorithms.
The sensor measures the optical refl ections of an object on a cover above the sensor using a system so called HALIOS® (High Ambient Light Independent Optical System). HALIOS® is high effi cient suppressing ambient light and also has an inherent self calibration to eliminate disturbances caused by housing refl ections such as scratches.
