Safety controllers for mobile machines are specialized devices designed to enhance operational safety in industrial and mobile equipment. These controllers are typically produced by leading automation and safety technology companies, such as Sick AG (Germany), Pilz GmbH (Germany), and Rockwell Automation (USA). They serve industries like construction, agriculture, material handling, and logistics, ensuring compliance with safety standards like ISO 13849 and IEC 62061. Key products include safety PLCs, emergency stop modules, and speed monitoring systems, which prevent accidents by halting hazardous movements or triggering alarms. Brands like Sick's Flexi Soft or Pilz's PNOZ are widely recognized in this category.
