The optical design prevents the sensor from being tricked by specular
reflections, allowing it to detect optically engineered
surfaces such as mirrors, LCD glass with polarizing films, and
semiconductor wafers. Easily configurable using either the push button on the sensor or via
a remote input line, three switching thresholds—light, medium or dark,
depending on the target's transparency level—can be selected to
optimize detection and maximize sensing stability. Small changes in
environment are filtered out by the microcontroller.
