The Harmony XB4/ZB4 series made of metal offers a wide range of 22mm and 30mm control and signalling devices such as pushbuttons, indicator lights and selector switches through to emergency stop switches. Thanks to the modular design of the devices, it is possible to purchase all components as individual elements, in assemblies or as complete devices. Thanks to their quality, flexibility and extreme robustness (protection classes up to IP69K), the devices are ideal for most applications in industry and buildings. This ergonomic push-button front element is individually customised via an online configurator. The front element is mounted in a 30 mm hole. It is attached using a vibration-resistant connection screw. To create a complete device, this front element can be combined with a mounting flange and a variety of different auxiliary switches and accessories. In addition to high vibration resistance and a very long service life, the devices in the XB4/ZB4 series are also characterised by an extremely high possible ambient temperature. Suitable for international use due to the large number of existing product standards and certifications.
