Designed for harsh environments, the PSE piezoelectric switch comes with a pre-assembled polyurethane cable to offer maximum flexibility and the highest IP protection during installation. The housings of the factory assembled piezoelectric PSE family are made of stainless steel 1.4462. This steel is characterised by its particularly high resistance to corrosion, which is essential in areas with high humidity. The PSE switches offer maximum reliability and a long service life (20 million actuations). Hermetically sealed housings make the PSE with cable predestined for use in particularly harsh and inhospitable applications.
