Schmersal 施迈赛 AZ17 安全监控系统

"Safety switches with separate actuators 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 safety control modules all safety switches with class 2 shown in this chapter achieve Control Category 3 or 4 to EN ISO 13849-1. 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. Enclosure rating of all the safety switches is IP 67. The safety switches can be fitted in any desired mounting position."
