Certified, reliable and comprise of no mechanical switching contacts in aluminium or stainless-steel housings

To provide better safety in potentially explosive atmospheres such as refineries (petrochemical industry), mills (food processing), gas works, the chemical industry and others areas, the switches from SCHURTER PSE EX family feature aluminium or stainless-steel housings, offering maximum reliability and long service life.

Due to their hermetically sealed housing (IP69K) with no mechanical switching contacts, they are designed for use in potentially explosive installations above ground, as well as in areas with flammable air-gas mixtures, vapours and dust.

Comprising of two directives in the field of explosion protection namely ATEX Product Directive 2014/34/EU and the ATEX Operating Directive 1999/92/EC (ATEX derived from the French abbreviation for ATmosphères EXplosibles), the products are certified and safe to be used and operated in potentially explosive atmospheres.

In addition to the European ATEX certification, all SCHURTER PSE EX products are also validated by the internationally-recognised IECEx certification. For a manufacturer to offer ATEX/IECEx certified products, both product and production site certifications are required. A surveillance audit of the PSE EX production site was last certified on 19.08.2020.
