By achieving the seal-tight protection class of IP69K, Schurter is extending the spectrum of potential applications for its already tried and tested PSE family of Piezo switches.
The qualification test was carried out at 90bar and at a temperature of 80 degrees C.
The hermetically sealed Piezo switches can now be used in areas which are regularly disinfected or cleaned using high pressure cleaners such as auxiliary equipment, external control panels, outdoor electrical appliances and electrical enclosures.
The following sizes are available as standard: 16, 19, 22, 24, 27 and 30mm. Other mounting diameters, materials, colours and shapes are possible according to individual design requirements.
PSE family of Piezo switches are available from Koloona Industries .
