Position switches from Steute with or without safety function
With the Ex 99, the Steute ‘Extreme’ business unit offers a new series of position switches developed especially for extreme applications and conforming to DIN EN 50041 dimensions. These ‘extreme’ conditions include use in explosive environments. The new switching devices have therefore been tested and approved in accordance with ATEX and IECEx for use in gas Ex zones 1 and 2, as well as dust Ex zones 21 and 22. A further extreme criterion is suitability for low temperatures. The Ex 99 series can be used in temperatures down to –60°C.
The housings in the new position switches are made out of high-quality fibreglass-reinforced plastic. This material guarantees that even after an impact test at –60°C the high protection class of the switchgear (IP 66) is maintained.
