Purpose
The safety switches with separate actuator are suitable for sliding, hinged, and removable safety guards, which need to be closed to ensure the necessary operational safety. They are used for applications in which the hazardous situation is terminated immediately when the safety guard is opened. When the safety guard is opened, the NC contacts are positively opened, and the NO contacts are closed. The safety switchgears are classified according to EN ISO 14119 as type 2 interlocking devices. The user must evaluate and design the safety chain in accordance with the relevant standards and the required safety level. The entire concept of the control system, in which the safety component is integrated, must be validated to the relevant standards.

Warning about misuse
In case of improper use or manipulation of the safety switchgear, personal hazards or damage to machinery or plant components cannot be excluded. There are no residual risks, provided that the safety instructions and the instructions regarding mounting, commissioning, operation, and maintenance are observed.
