20 mProduct details
Light barrier set for interior and exterior monitoring
The light barriers can be installed between windows and roller shutters, offering a maximum range of 20 m indoors and 10 m outdoors. Detection is achieved through six light beams with a wavelength of 940 nm. It is possible to install multiple light barriers in parallel or in series. Synchronization occurs optically.
Aligning the light barriers is straightforward and does not require additional calibration tools. Three different operating modes are available: point-to-point, parallel, and crossed beam bundles. The housing is made of robust polycarbonate, providing high impact and weather resistance. Additionally, the light barrier features an alarm memory. The normally closed alarm contact is suitable for use in alarm systems.
The light barrier is equipped with an opening and theft protection and can be used in protected outdoor areas.
