Application:
The safety switches with separate actuators are suitable for sliding, hinged and especially for removable safety guards, which need to be closed to ensure the necessary operational security. They can also be fitted on profile sections and retrofitted on existing equipment.
All class 2 safety switches shown in this chapter control category 3 or 4 to ISO 13849-1 in combination with a guard door monitor.
Design and mode of operation:
On the class 2 safety switches, the switching element is not physically connected to the actuator but functionally brought together or separated when switching. When the safety device is opened, the actuator is separated from the base device. During this process, the NC contacts in the safety switch are positively opened and the NO contacts closed.
Enclosure rating of all the safety switches is IP 67. The safety switches can be fitted in any desired mounting position.
