Omron D4JL-2NFA-D6 Guard Lock Safety Interlock

The Omron D4JL-2NFA-D6 guard lock safety switch from the D4JL series combines a mechanical interlock with a solenoid guard lock to enforce secure guard locking on hazardous machinery. It is designed for robotic cells, packaging lines, CNC equipment, and automated production environments, ensuring machine shutdown whenever a guard is open. This IP67-rated unit features a key-operated head, 2NC + 1NO contacts, and a lock option that is power-to-lock or power-to-release (model dependent). It operates at up to 240 VAC or 250 VDC, with a rated current of about 3 A (AC-15) or 2 A (DC-13), and ships with a pre-wired 6 m cable for panel or door mounting. The safety switch complies with ISO 14119 and IEC/EN 60947-5-1, and its operating temperature range is -10°C to +55°C. The part number is D4JL-2NFA-D6, and it is commonly used for replacement or retrofit in machine safety interlock installations, with compatibility noted alongside related Omron models such as D4NL-2NFA-B, D4SL-N2NFA-D, and D4NS-2AF.
