package
The infrared emitting diodes (IRED, signal diodes) and the photo-
diode are placed on a PCB in a required formation. The ability to
detect the motion of an object on the surface depends on chang-
es in the optical path of the reflected signal, changing the relative

light intensity of LED pairs.
The sensor measures the optical reflections of an object on a cov-
er above the sensor using a system so called HALIOS® (High Ambi-
ent Light Independent Optical System). HALIOS® is high efficient
suppressing ambient light and also has an inherent self calibra-
tion to eliminate disturbances caused by housing reflections such
as scratches.
DESCRIPTION
The IC is an optical sensor which provides a non-mechanical de-
tection of movements. The EEPROM allows a free configuration of
the sensor-structure and the detection algorithms.
