Protective field
T
he protective field protects the hazardous area of a machine or vehicle. As soon as the
electro-sensitive protective device detects an object in the protective field, it switches
the associated safety outputs to the OFF state. This signal can be passed to controllers
resulting in the dangerous state coming to an end, e.g. to stop the machine or the
vehicle.
