Allen-Bradley 440G-MT47045

The Rockwell Automation 440G-MT47045 positive-mode tongue-operated guard locking interlock switch is engineered to ensure optimal safety for both personnel and machinery. This advanced device locks the machine guard until power is isolated while the guard is open, providing a critical layer of protection. It features a power-to-release mechanical lock, allowing access only when a signal is provided to the internal solenoid. Classified as a Type 2 Interlocking Device, this switch meets the stringent ISO 14119 standards, making it suitable for performance levels PLe or PLd, as well as SIL 2 or SIL 3 systems depending on the application. Built with a heavy-duty die-cast alloy housing, the switch is resilient in harsh conditions. It also includes an optional diagnostic version with built-in status indicators for additional functionality. With impressive performance metrics, including a mechanical longevity of over two million operations and a mean time to failure of over 385 years, the 440G-MT47045 is a trustworthy choice for critical safety applications. Ideal for diverse environments, this switch combines durability with reliability to enhance operational safety.
