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

Omron D4NL-1HFG-B Guard Lock Safety-Door Switch is an industrial guard-lock interlock that secures safety doors on equipment, preventing access while the machine is energized and enabling safe operation. It is rated for 3 A at 240 VAC and provides DPST-NC contacts (3PST-NC listed in the data) for normally closed signaling of multiple circuits when the door is closed. This Omron device from the D4NL family is designed for rugged industrial guarding in applications such as presses, conveyors, and automated tooling, offering reliable interlock action and door-lock detection. Use it to enforce safe access to guarded areas, ensuring the door must be closed (and the guard engaged) before machine controls can be released or cycles started.
