The aluminium surface of Schurter's PSE HI switches can be produced in various anodized colors. A variety of standard legends and/or raised symbols are offered to indicate function. The laser etched legends or pre-formed raised symbols provide long-term protection against wear. Raised symbols can be numbers, as well as characters from the Braille alphabet. These flexible design options make it possible to offer a wide variety of standard or custom options to meet individual design requirements.
The piezo switches have an ingress protection class rating of IP67. The hermetic seal makes the switches ideal for use in areas that must be regularly cleaned or disinfected. Additionally, the switches offer a robust metal housing, well suited for use in harsh environments where there exists the potential for vandalism. The impact resistance according to DIN EN 50102 is IK06.
The PSE HI piezo switch is rated 0.1A @ 42 VAC/60 VDC. The piezo switching element offers an exceptionally long service life of more than 20 million switching cycles. Typical applications requiring such robust switch performance include pedestrian crossing walks, elevators, truck lifts, material-handling equipment, safety equipment, ticketing terminals, gas stations, food service equipment and processing plants.
