New design and innovative features protect sensitive components even in demanding environments. Thanks to the integrated hinge a comfortable access to the interior is ensured and the wiring between the assemblies in the lid and the lower part are perfectly protected. The high degree of protection of IP69 is achieved with only two cover screws. These are â like all other fixing elements â invisibly mounted under design covers. The lower section has a molded receptacle for a pressure compensating diaphragm (Conrad 1483273) , which can be activated at the factory. All housing components are made of metal and are thus optimally suitable for use in rough environmental conditions.This text is machine translated.
