Omron D4N-912G Limit Switch
Omron D4N-912G is a snap-action limit switch with an adjustable roller lever, form lock, metal lever, and resin roller. It uses 1NC/1NO contacts and a 1-conduit, M12 connector configuration, with operating speed specified from 1 to 500 mm/s. Operation frequency is 30 operations/minute maximum, while IP67 protection is listed. Rated insulation voltage is 300 V at 50/60 Hz. The D4N-912G belongs to the D4N Series within the adjustable roller lever switch range from Omron. Its form-lock actuator, resin roller, M12 connector, 1NC/1NO contact form, and snap-action mechanism provide the main model-level attributes that distinguish this version from conduit-based adjustable roller-lever models.

The Omron D4N-912G Limit Switch uses an adjustable roller lever with form lock, a metal lever, and a resin roller. It has 1NC/1NO contacts, snap-action operation, and a 1-conduit, M12 connector configuration. Operating speed is specified from 1 to 500 mm/s, and operation frequency is 30 operations/minute maximum. Contact resistance is 25 mΩ maximum, insulation resistance is 100 MΩ minimum, and rated insulation voltage is 300 V at 50/60 Hz. IP67 protection is listed, with operating temperature from -30 to 70°C and humidity up to 95%.
Malfunction vibration resistance covers 10 to 55 Hz at 0.75 mm single amplitude. Destructive shock resistance is 1,000 m/s² minimum and malfunction shock resistance is 300 m/s² minimum. D4N-912G is best identified through the adjustable form-lock roller lever, metal lever, resin roller, 1NC/1NO contacts, snap-action mechanism, and M12 connector configuration. This combination separates it from standard conduit versions without requiring assumptions about directional movement or installation. Among the current D4N variants, the M12 connector and resin roller are the clearest secondary identifiers because the electrical limits and 1NC/1NO snap-action format overlap with other models. A related current D4N model also uses an adjustable form-lock roller lever and 1NC/1NO snap-action contacts, but its actuator has a rubber roller and its connection is listed simply as 1-conduit.
