Omron D4NL-2GFA-B Safety Door Interlock Switch

The Omron D4NL-2GFA-B is a safety door interlock switch with guard lock from the D4NL Series, designed to prevent machine operation whenever a guarded door is open in robotic cells, packaging lines, CNC equipment, and automated production lines requiring guarded access. It uses a mechanical interlock with a solenoid lock, a key-operated actuator, and safety contacts configured as two NC plus one NO. Rated up to 240 VAC / 250 VDC with typical currents of 3 A (AC-15) or 2 A (DC-13), it carries IP67 protection and mounts to panels or doors via a terminal block connection. This ISO 14119 and IEC/EN 60947-5-1 compliant device from Omron supports power-to-lock or power-to-release locking (model dependent) and operates reliably in -10°C to +55°C environments.
