Omron D4NL-2BFA-B Guard Lock Safety Door Switch

The Omron D4NL-2BFA-B Guard Lock Safety Door Switch is a robust interlock for machine safety systems, using an electromagnetic guard locking mechanism to ensure machines cannot operate while guards are open. With a 24 VDC solenoid and a 2NC + 1NO contact configuration, it provides safe electrical signaling for industrial control circuits and can be wired through terminal or pre-wired cable entries (model dependent). The device features a separate actuator key system for controlled operation, and its IP67-rated enclosure blends industrial-grade reinforced plastic and metal for harsh environments. Mount it on a panel or surface, and rely on ISO 14119 compliance for compatibility with standard safety guards. Commonly installed in robotic cells, CNC machines, packaging lines, automotive manufacturing, material handling systems, and food processing equipment, the D4NL-2BFA-B helps keep operators protected by ensuring guard locking and safe operation whenever guards are closed.
