Omron D4NL-1CFA-B Guard Lock Safety-Door Switch

The Omron D4NL-1CFA-B Guard Lock Safety-Door Switch interlocks and locks machine guard doors in industrial safety systems for controlled access and operator protection, with common installations in robotic cells, packaging machines, CNC equipment, and automated production lines. It combines safety contacts with a guard-lock mechanism, a key-operated actuator, and a mechanical guard lock, and is IP67 protected for use in dusty or wet environments, mounting via panel or machine attachment with a terminal-block connection. The unit is rated for 24 VDC / 240 VAC and has a model-dependent rated current, designed for safety-critical environments that require both door monitoring and guard locking; it is part of the Omron D4NL Series and complies with applicable industrial safety standards (model dependent). Operating temperature ranges from -30°C to 70°C, ensuring reliability in diverse factory conditions. Common replacements to consider include Omron D4NL-2CFA-B, Omron D4NS-1AF, and Omron D4BL-1DRB.
