The key-actuated lock mechanism prevents the door from opening until the machine controller signals that the hazard has been cleared — the 4NC contact configuration provides the positive-break safety signal back to the safety relay or PLC. Rated IP67, the switch body and key entry withstand washdown and temporary immersion, making it a fit for food-and-beverage lines, packaging floors, and outdoor machine guarding where hose-down cleaning is routine. The 39 x 39 x 180 mm footprint is compact for a guarded locking switch — it fits into the cutout of the D4SL family without requiring a larger panel opening than the predecessor models. ## Switching capacity and contact duty The 4NC contacts are rated 1.5 A at 120 V AC and 220 mA at 125 V DC. These are signal-level currents, not load-switching ratings — the switch feeds into a safety monitoring relay or PLC input, not directly to a motor contactor coil above its rating. Electrical life is specified at 150,000 cycles under rated load; mechanical life reaches 1 million cycles. For a guard door opened 50 times per shift, the electrical life translates to roughly 10 years of service before contact replacement is needed — the mechanical life is not the limiting factor in most production environments. Termination is via a terminal block inside the switch body — no pre-wired pigtail or M12 connector. Field wiring lands directly on screw terminals, which simplifies replacement without unseating a connector but requires access to the switch interior for installation. ## Mounting orientation and actuator alignment The switch accepts key entry from four head directions — the actuator head can be rotated to face up, down, left, or right relative to the switch body. This lets the same switch align with a sliding door (horizontal key entry) or a hinged door (vertical entry) without a separate bracket or adapter. The 39 mm width and 39 mm depth match the standard D4SL mounting pattern — replacement of an existing D4SL unit requires no panel modification or re-drilling. Sourced to order against the BOM quantity through independent distribution channels.","metaTitle":"Omron D4SLN4EDAD Guard Lock Safety Switch, 4NC, IP67","metaDescription":"Omron D4SLN4EDAD guard-lock safety-door switch, 4NC contacts, IP67, terminal block. 39x39x180 mm.
