Applications of optoelectronic sensors

Use of safety laser scanners

Optimum safeguarding of danger zones with safety laser scanners

Whether you need stationary or mobile safeguarding of danger zones and access monitoring, safety laser scanners PSENscan provide the optimum solution for your application. They enable two-dimensional area monitoring with an opening angle of 275 degrees. Protected fields and warning fields can be freely configured and adapted to structural conditions. As a result, PSENscan can easily be integrated into the most varied of applications.


The light barrier for all industries and applications

With PSENopt you can protect your staff and capital goods – safely, efficiently and economically. An invisible protected field from the infrared light barrier protects the danger zones. If a light beam is broken it will immediately trigger a safe shutdown command. Muting, blanking and/or cascading open up a wide range of possibilities for optimum incorporation of the light barrier into your plant. They are therefore suitable for a wide range of industries and applications.
