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

The Omron D4NL-2GFA-B safety door switch with guard lock provides robust protection for industrial safety systems, interlocking guard doors on hazardous machinery and preventing operation when doors are open, with common use in robotic cells, packaging lines, CNC equipment, and other automated production lines that require reliable interlock protection. This D4NL-series device combines a mechanical interlock with a solenoid lock, offering a 2NC + 1NO safety contact configuration and a key-operated head for deliberate actuation. Locking can be power-to-lock or power-to-release depending on the model, and it supports rated voltages up to 240 VAC / 250 VDC with typical currents of 3 A (AC-15) or 2 A (DC-13); it is IP67-protected, uses a terminal-block connection, and is panel/door mountable for straightforward retrofits. Operating from -10°C to +55°C and conforming to ISO 14119 and IEC/EN 60947-5-1, it suits applications where controlled access and emergency-stop integration are critical for safety. Common replacements include Omron D4NL-4GFA-B and D4NS-2AF for ongoing maintenance and upgrades in manufacturing environments.
