These piezo keypads are impervious to all kinds of dirt and fluids, making them suitable for use in outdoor applications. They resist ambient conditions such as negative temperatures, ice and snow. They offer IP69K protection and an operating temperature of -25 to 85°C. An accessory kit enables the keypads to be sealed into the housing with IP68 protection. As a standard, the keypads are available as a number block with 12 or 16 keys and an aluminium front. Point illumination may be integrated into the individual key fields as optical feedback or for user navigation. Several colours in both the aluminium and stainless steel are available. It can be adapted to customer requirements with respect to outer geometry as well as the number and arrangement of the keys. By using the piezo principle, the keypads are free of mechanical parts and offer a lifetime of more than 20 million actuations. The completely sealed operating panel is easy to clean and resistant to common cleaning agents. The metal surface with an IK05 impact strength renders the pads highly resistant to impacts.
