The Harmony XB4/ZB4 metal series offers a wide range of 22mm and 30mm control and signaling devices such as push buttons, indicator lights and selector switches through to emergency stop switches. The modular design of the devices makes it possible to purchase all components as individual elements, in assemblies or as complete devices. Due to their quality, flexibility and extreme robustness (protection classes up to IP69K), the devices are ideal for most applications in industry and in buildings. This auxiliary switch block is compatible with the 22mm and 30mm devices and has 1 normally open contact and 2 normally closed contacts. The auxiliary switch block is connected using screw terminals. It is attached using a shock-proof connection screw. In addition to high vibration resistance and a very long service life, the devices in the XB4/ZB4 series also impress with an extremely high possible ambient temperature. Suitable for international use due to the large number of existing product standards and certifications. Thanks to the Green Premium ecolabel, you can obtain detailed information on material content, environmental impact and circular economy that supports your sustainability goals.
