The BOS 6K miniature photoelectric sensor from Balluff Inc. can reliably identify transparent objects, regardless of their shape, color or composition. Measuring 32-by-20-by-12mm3, the retroreflective sensor's low hysteresis makes it suitable for detecting such transparent objects as glass bottles, test tubes or transparent films in industrial and packaging applications.

The BOS 6K sensor design uses the autocollimation principle, i.e. the emitter and receiver are on the same optical axis to ensure a high degree of switching accuracy, said the company. A built-in polarizing filter suppresses interference such as reflections, thus increasing process reliability.

Available now, the photoelectric sensor is priced from $125 to $400, depending on the model.
