This is typical for guard monitoring where a fault (welded contact) must be detectable — the slow-action mechanism ensures positive opening per IEC 60947-5-1, so the contacts are mechanically forced apart even if welded. The 2.5 A Ith rating covers the signal-level loads in a safety PLC input or relay coil; it's not a power-switching contact. ## Deployment context This is a slim safety door switch — the slim body saves DIN-rail or panel space in multi-door guarding applications (e.g., light curtain bypass, interlock on access panels for conveyors or packaging machines). The 3 m cable reaches from the door frame to a junction box or safety relay module without a splice. Vertical key insertion (T-type) means the actuator enters from above — common on hinged doors where the switch mounts on the fixed frame and the key on the door edge.","metaTitle":"Omron D4GS-N4T-3 Slim Safety Door Switch, 3NC, 3m Cable","metaDescription":"Omron D4GS-N4T-3 slim safety door switch with 3NC slow-action contacts, 3m cable, vertical key insertion.
