Omron D4N-112H Limit Switch
Omron D4N-112H is a snap-action limit switch with an adjustable roller lever, form lock, metal lever, and rubber roller. The model uses a 1NC/1NO contact form and a 1-conduit configuration, with operating speed specified from 1 to 500 mm/s. Operation frequency is 30 operations/minute maximum, and IP67 protection is listed. Rated insulation voltage is 300 V at 50/60 Hz. The D4N-112H belongs to the D4N Series within the adjustable roller lever switch range from Omron. Its form-lock actuator, metal lever, rubber roller, 1NC/1NO contacts, and snap-action mechanism provide the key model-level characteristics that separate it from fixed roller-lever and plunger D4N versions.

The Omron D4N-112H Limit Switch uses an adjustable roller lever with form lock, a metal lever, and a rubber roller. It has a 1NC/1NO contact form, snap-action mechanism, and 1-conduit configuration. Operating speed is specified from 1 to 500 mm/s, while 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. The model carries IP67 protection and operates from -30 to 70°C with no icing, with humidity specified up to 95%.
Malfunction vibration resistance is 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. The adjustable form-lock roller lever is the strongest model-specific identifier, followed by the metal lever, rubber roller, 1NC/1NO contacts, snap-action mechanism, and single-conduit format. These exact terms are useful for matching D4N-112H against other D4N versions without assigning an unlisted actuator effect or application. Within the current D4N data, several electrical limits are shared, so the adjustable lever materials, action type, contact form, and connection format provide the more specific model distinction. A related current model also uses an adjustable form-lock roller lever and 1NC/1NO snap-action contacts but has a resin roller and M12 connector configuration. See D4N-912G.
