Omron D4N-1122 Limit Switch
Omron D4N-1122 is a snap-action limit switch with a roller lever made from a resin lever and resin roller. It uses a 1NC/1NO contact form and a 1-conduit configuration, while operating speed is specified from 1 to 500 mm/s. Operation frequency is 30 operations/minute maximum, with IP67 protection and 25 mΩ maximum contact resistance. Rated insulation voltage is 300 V at 50/60 Hz. The D4N-1122 belongs to the D4N Series within the roller lever limit switch range from Omron. Its resin roller-lever construction, 1NC/1NO contacts, snap-action mechanism, and single-conduit format form the main product attributes for identifying this D4N version.

The Omron D4N-1122 Limit Switch combines a roller lever made from a resin lever and resin roller with 1NC/1NO contacts and a snap-action mechanism. It uses a 1-conduit configuration and operates over a speed range from 1 to 500 mm/s. Operation frequency is specified at 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, together with an operating temperature range from -30 to 70°C with no icing 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, while malfunction shock resistance is 300 m/s² minimum. The resin roller-lever construction, 1NC/1NO contact form, snap-action operation, and single-conduit format are the most useful identifiers for this D4N model. The supporting resistance, voltage, speed, frequency, vibration, and shock values define the electrical and mechanical limits without introducing application claims. Across the current D4N rows, the 25 mΩ contact resistance, 300 V insulation rating, speed range, and IP67 value are common supporting specifications, while actuator, action type, and conduit identify the variant. A nearby D4N model keeps the same 1NC/1NO snap-action contact arrangement but uses an adjustable roller-lever construction. See D4N-112H.
