Glossar

A photoelectric sensor is an optical sensor used for non-contact detection of objects or motion. It detects when a light beam is interrupted or reflected and triggers a switching signal based on this detection.

Light barriers are used in conveyor technology, intralogistics, and industrial automation to detect packages, control processes, or trigger measurement operations. Depending on their design, they operate as through-beam, retro-reflective, or scanning light barriers. In automated measurement and DWS systems, they are often used to detect the position of an object and determine the optimal time for measurement or identification.

Practical example:

On a conveyor line, a photoelectric sensor detects the arrival of a package and automatically starts the measurement and scanning process of the DWS system.
