Connection to Decentralise Peripheral System


EUCHNER’s MGB (Multifunctional Gate Box) is a unique interlocking or guard locking system for the protection of safety doors on machines and systems. It is more than a safety switch, more than a bolt, and offers a lot more functionality. The basic system comprising the handle module and interlocking/locking module includes numerous functions. Guard locking, escape release or other functions such as buttons for start/stop and Emergency stop are available. The MGB is now even more versatile and flexible. The recently updated version is equipped with changeable color lenses for pushbuttons. The pushbuttons can easily be modified by the customer for wanted colors. Due to its modular design, a control module can be added, quickly becoming a small operator panel.
