It carries an IP67 protection rating, so it handles washdown environments and dusty panels without a secondary enclosure. Termination is via terminal block — no pre-wired pigtail to manage. Rated switching current is 1.5 A AC at 120 V and 220 mA DC at 125 V. That covers control-circuit interlocking on 120 VAC or 125 VDC safety loops; it is not sized for motor power switching. The 6NC contacts give six normally-closed channels, which means you can wire multiple safety zones or dual-channel monitoring without adding auxiliary blocks. Mechanical life is rated at 1 million cycles; electrical life at 150,000 cycles. The 4 head directions allow the actuator entry to face any of four sides, easing alignment on hinged or sliding guards. Dimensions are 39 mm wide by 39 mm deep by 180 mm tall — a compact footprint for a guard-locking switch, though the 180 mm height means it needs clearance above the mounting plane.","metaTitle":"Omron D4SLN4RFAD Guard Lock Safety-Door Switch, 6NC, IP67","metaDescription":"Omron D4SLN4RFAD guard lock safety-door switch with 6NC contacts, IP67, terminal block.
