OMRON D4N-112G Safety Door Switch

The OMRON D4N-112G (D4N-112G) is a safety door switch designed for industrial machinery safety monitoring and interlock applications. Operating as part of the Omron D4N series, this safety switch is engineered to verify the closed position of movable guards, machine doors, access gates, and safety covers across automated production environments. It plays a critical role in safeguarding personnel and equipment by detecting opening actions and interrupting hazardous machine movements when protective barriers are breached. Constructed for demanding industrial environments, the D4N-112G serves as a direct replacement component for preventive maintenance, system overhauls, and equipment repair. The unit has a listed weight of 10 kg and integrates into standard safety circuits, control cabinets, and guard door mechanisms. Typical applications include manufacturing lines, packaging equipment, material handling systems, and automated machine tooling where reliable guard position sensing is essential to ensure operational integrity and compliance with machine safety standards.
