The 1NO + 4NC contact configuration means one normally-open feedback channel for the safety controller and four normally-closed channels wired in series for the safety circuit — a layout that gives you redundancy for the safety loop plus a separate monitoring path, all in a single housing. Rated for 3 A at 240 VAC and 270 mA at 250 VDC, so it handles the signal-level loads typical of safety PLC inputs and contactor coils. The IP67 rating means the switch body and the key entry are sealed against washdown — suitable for food, beverage, or pharmaceutical lines where hose-down cleaning is routine. Screw terminals accept 0.5–2.5 mm² stranded or solid wire. The four head directions (entry from top, bottom, left, or right) let you orient the actuator approach to match the door swing without additional cams or adapters. Panel cutout dimensions follow the standard D4NL footprint — 88.5 mm wide × 95 mm tall, 35.5 mm behind the panel. ## Electrical endurance Mechanical life is rated at 1 million cycles; electrical life at 500,000 cycles at rated load. That's typical for a solenoid-lock switch in this class — the mechanical figure governs door-open/close wear, while the electrical figure reflects contact erosion under the rated switching current. For light signal-level loads (24 VDC, 10–50 mA), the electrical life extends well beyond the catalog number.","metaTitle":"Omron D4NL4FFGB Safety Door Switch, 1NO/4NC, IP67, Screw Ter","metaDescription":"D4NL4FFGB safety-door switch with solenoid lock, 1NO/4NC contacts, IP67, screw terminals.

It switches 3 A at 240 VAC or 270 mA at 250 VDC. The housing is rated IP67. Mechanical life is 1 million cycles; electrical life is 500,000 cycles at rated load. Termination is via screw terminals, and the actuator key can enter from four directions."},{"question":"What is the closest alternative to the D4NL4FFGB in the same family?","answer":"Within the D4NL series, the closest alternative is a variant with the same 1NO/4NC contact configuration and solenoid lock but a different actuator head orientation or key type. The D4NL4FFGB uses a key actuator with four head directions; if your application requires a different actuator style (e.g., hinge or tongue), choose the corresponding D4NL variant. Contact configuration and IP rating remain consistent across the series."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/omron/D4NL4FFGB","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/omron/D4NL4FFGB when reusing this data.
