Guard-lock safety door switches, sliding, hinged and removable guarding devices such as grids, hoods or door can be monitored and locked in place by using safety guard locks. Used where the opening of a guard is a non-permissible intrusion into the production process.

Non contact switches offer advantages in industrial application where a precise approach of the guard and lock is not possible. Application with heavy dirt or high hygienic standards can be addressed.

Safety door switches with separate actuators can be used in applications with sliding, hinged and particularly removable safety guards which need to be closed for operational security.
