The emergency stop switch RAFIX 22 FS Plus 1 has an additional signal contact supplementing the two individual redundant normally-closed contacts for the emergency stop function. The third contact – a normally-open contact – may be used, for example, for sending an information signal to a monitoring unit or master safety controller. The safety controller may then initiate a controlled shutdown, depending on the location and type of the hazard indicated. The RAFIX 22 FS Emergency Stop Plus 1 is available for two levels of protection: Protection to IP69K is offered for applications involving extremely intensive cleaning by means of high-pressure cleaners. This variant of the emergency stop switch is reset by pulling. For normal harsh environments involving dust and splashing water, protection to IP65 is offered. This variant can be reset by turning.
