Where there is one extreme condition, the next is not far away - Ex position switches and Ex magnetic sensors down to -60 °C

Subzero temperatures, humidity, explosive atmospheres: in process engineering the conditions for switchgear applications can often rightly be described as extreme. The steute Extreme business unit has developed special ranges for just such conditions. They include standard position switches and magnetic sensors for explosive environments in temperatures down to -60 °C.

Wireless also possible in Ex zones

When switching devices no longer require power cables and can radio their signals out of their environment, the advantages can be considerable depending on the application in question. Wireless switches are beneficial wherever access in the plant following installation is restricted. The benefits of wireless switchgear technology are now increasingly appreciated in Ex zones as well. steute has a wide range of certified Wireless Ex switches for such applications.
