The Elan range of control devices and indicator lights for the 22.3 mm industrial standard meets the requirements of the Atex directive. The entire Ex programme has a modular design. Each control device consists of contact elements, the mounting flange and the operating or display element. The modular design facilitates the assembly and allows a great diversity of variants. The front sealing of the devices meets the requirements for explosion protection and furthermore features a long lifetime, even in extreme ambient conditions. The control devices can be installed in zones 1 and 2 as well as zones 21 and 22 of potentially explosive atmospheres.
