U-system photo sensors

Overview

The Schlüter universal system, or U-system for short, enables the use of photo sensors in the M18 (SPM-18) and M30 (SPM-30) designs and fiber optics in a wide variety of applications. Few basic devices are supplemented by a large number of different fiber optics. Due to their robust design and the complete encapsulation with silicone, the sensors are very insensitive to vibrations, impacts and mechanical loads.

The lack of optical focusing and the associated high transmission energy make the devices insensitive to dust, steam and dirt. Still, the devices are safe for humans as they do not use laser light and invisible infrared light is not focused on the retina.

The glass fiber optics enable use in tight, inaccessible places and at temperatures of up to 300 ° C. If installed appropriately, it can be used as a light barrier in industrial ovens with an internal temperature of over 1.000 degrees. Small objects can also be detected at distances of up to 4 m.

But the devices can also be used without problems in Siberian cold.

The U-System is therefore often used wherever difficult conditions prevail and years of trouble-free operation are still necessary.

There are customers who have been using the Schlüter U-System photo sensors for decades without problems.
