Multifunctional Gate Box

Gate Box


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 MGB will work on both hinged and sliding doors. The basic system comprising of 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 recently updated version is equipped with changeable color lenses for pushbuttons, allowing the customer to use their desired colors. And with its modular design, an MGB control module can be added to function as a small operator panel.

The MGB safety system can be connected to almost any safety relay or to any safety control system. With a safety control system, the short circuit monitoring on the safety control system must be disabled as this function is performed by the MGB. Performance Level e is retained.
