February 23, 2010 - By locking the guard closed, Vigilguard will prevent access to the machine till it has come to a safe stop, and differentiates by its non-contact design, allowing a much longer life expectancy. There is no ruining, the actuation is smooth contrary to traditional mechanical switches. It reaches without relay safety category 4 as per EN954-1 and PLe as per ISO EN13849-1.This compact device features a coded bolt, recognised by the striking plate providing a tamper resistant locking thanks to its electronic process.
The machine won't restart unless it is correctly actuated.Housed in a very resistant metal housing (zamak), it overpasses heavy contamination, vibrations and poor switch alignment. The main innovations are the guided and recognised bolt into the striking plate, the washable striking plate thanks to a central hole for water release, the double connector available, to ease the serial wiring, and facilitate the automatic serial locking, and an energy saving mode, to avoid unnecessary consumption. Easy and quick to install as no minimum closing radius is necessary, it is marketed also with M12 connector or cable.
