Safety switch with separate actuator / Class 2 


Application:

AZ and ST range safety switches are suitable for sliding, hinged and particularly removable safety guards, which need to be closed to ensure the necessary operational security. They are also suitable for fitting on profile sections and existing equipment.
In combination with AES and AZR range safety control modules (see 10.1 and 10.2), all safety switches with class 2 shown in this chapter achieve Control Category 3 or 4 to EN 954-1.

Design and mode of operation:
On the safety switches with class 2, the switching element is not physically connected to the actuator but functionally brought together or separated for switching. When the guarding device is opened, the actuator is separated from the base unit. In the process, NC contacts are positively opened and NO contacts closed.
A wide range of accessories is available for these safety switches, including various coded actuators, individually coded actuators, also suitable for small radii, lockout tags and various latching devices such as magnets and ball latches. Enclosure rating of all the safety switches is IP 67.The safety switches can be fitted in any desired mounting position.
