Bringing light to darkness

The films used in the packaging industry vary greatly. Come are more or less transparent and sometimes even dark or metallised. This makes it challenging for photoelectric sensors to reliably detect the position of the objects in the packaging. With its LS25CI, Leuze believes it can offer a solution. The sensor is said to be able to transilluminate any type of film which enables the reliable separation of products and sealing of the film in the right places. The infrared light used is harmless and poses no danger to the eyes.

System operators can pick from two models ­–  The LS25CI.XR1 high power can transilluminate dark films as well as identify individual transparent films. The photoelectric sensor can be configured via a potentiometer. For tougher requirements, the LS25CI.XX superpower transilluminates metallised and dark coloured films, even if they are multi-layered.

The housings of the transmitter and receiver meet protection classes IP67 and IP69K. They are also ECOLAB certified for use in harsh environments that require frequent cleaning. The devices are wired with M8 or M12 connectors and can thus be easily integrated into systems.
