Solenoid interlocks Thermoplastic enclosure Series STM 295 from page 10

Solenoid interlocks Range of application The solenoid interlocks ensure that sliding, hinged and removable guarding devices, such as grids, hoods or doors, cannot be opened until dangerous conditions (e.g. run-on movements) have been terminated. This takes place in co-ordination with the control system of a machine. Fail-safe standstill monitors or delay timers monitor run-on movements or time sequences. These solenoid interlocks are also used for cases in which the opening of a guarding device represents a non-permissible intrusion in a production process. In combination with the SRM range...

Safety switches with separate actuator Range of application 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 an appropriate safety control module, all safety switches shown in this chapter achieve SIL 3 according to EN 62061 and PL e according to EN ISO 13849-1. Design and operating principle On the safety switches with a separate actuator, the...
