IP67 is a type of protection that provides reliable information about the processing of a particular product.
A high degree of protection is optimal in the area of doorbells, because doorbells and pushbuttons are often exposed to the weather throughout the year.
The LED-pushbuttons at Edelstahl-Türklingel.de are IP67 certified. This means the following:
The first number, in this case 6 means: "Dust: Complete dirt against contact".
The second number, 7, says: "Water: protection against temporary immersion".
This means that you can easily leave your bell from our range outside for many years in direct weather conditions without expecting damage on material and technology.
