SCHURTER PSE EX explosion-proof piezoelectric switches

The piezoelectric switches in the SCHURTER PSE EX family feature aluminium or stainless steel housings, offering a 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.

In addition to European ATEX certification for operation in potentially explosive atmospheres, 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.

Explosion-protected components are recommended for use wherever explosive atmospheres can arise or prevail. Such atmospheres can occur in refineries (petrochemical industry), mills (food processing), gas works, the chemical industry and others. The switches are certified for above-ground applications, not for underground constructions.
