Fortress Interlocks is expanding its range of 'amGardPro' solenoid interlocks with the Slimline range of solenoid interlocks and operating elements, which are now available in a narrow version with a width of 40 mm. Thanks to their modular design, the solenoid interlocks for robust applications can be adapted to customer requirements and solve safety applications up to PLe (EN/ISO 13849-1). Their configuration options range from control module, emergency release and emergency stop to signal lamp. The 'Extracted Key' function offers increased protection by removing personal safety keys: before maintenance personnel enter the system, the safety key must be removed and taken into the system. If the safety door is closed unintentionally, the system cannot be started without the key.
