Piezo switches are sealed to the highest levels
Piezo switches sealed to IP69K can be used in equipment designed for areas that are regularly disinfected or cleaned using high-pressure cleaners.
Schurter has expanded the applications for its well established PSE family of piezo switches with the addition of a range of devices that are sealed to IP69K - the highest sealing rating possible.
The qualification test was carried out using a high-pressure vapour stream at 90bar and a temperature of 80C.
The hermetically sealed piezo switches can now be used in areas that are regularly disinfected or cleaned using high-pressure cleaners.
This renders them ideal for use in applications exposed to high levels of dirt and grime such as food processing, commercial cooking and transportation.
In addition to an extremely long lifetime of more than 20 million switching cycles, Schurter piezo switches feature a high level of robustness thanks to their stainless-steel or aluminium housings.
Standard mounting diameters are 16, 19, 22, 24, 27 and 30mm, and alternative sizes, materials, colours and shapes are possible, according to individual design requirements.
Point or ring illumination is available for 22mm and larger switches, with options for continuous illumination of the actuating surface or to signal the on/off switch position.
Schurter offers in-house laser engraving on short lead times, with a wide choice of standard legends and symbols, and the option for customer-specific inscriptions.
