Range of application
These safety switches with a separate actuator are suitable for sliding, hinged and particularly removable safety guards, which need to be closed to ensure the necessary operational safety. They are also suitable for mounting on profile sections and retrofitting on existing equipment.
In combination with a safety relay module series SRM, all safety switches shown in this chapter achieve PL "e" per EN ISO 13849-1 or up to SIL 3 per EN 62061, subject to suitable circuit arrangements.
Design and operating principle
On the safety switches with a separate actuator, the switching element is not physically connected to the actuator, but functionally united or separated by switching. When the guard device is opened, the actuator is separated from the base unit. In this process, NC contacts are positively opened and NO contacts closed.
The degree of protection of all the safety switches is IP 66. The safety switches can be fitted in any desired mounting position.
All safety switches shown in this chapter bear the CE mark according to the Machinery Directive 2006/42/EC.
