Omron D4N-1B22 Limit Switch
Omron D4N-1B22 is a slow-action limit switch with a roller lever consisting of a metal lever and resin roller. It uses a 2NC contact form and a 1-conduit configuration. Operating speed ranges from 1 to 500 mm/s, while operation frequency is 30 operations/minute maximum. IP67 protection, 25 mΩ maximum contact resistance, and 300 V rated insulation voltage are specified. The D4N-1B22 2NC Roller Lever Switch belongs to the D4N Series within the Omron Slow-Action Limit Switch Range from Omron Industrial Component Line. Its metal lever, resin roller, 2NC contacts, slow action, and single-conduit construction identify this model.

The Omron D4N-1B22 Limit Switch uses a roller lever consisting of a metal lever and resin roller. It has a 2NC contact form, slow-action mechanism, and 1-conduit connection. Operating speed is specified from 1 to 500 mm/s, with operation frequency 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. The operating temperature range is -30 to 70°C with no icing, while humidity is 95% maximum.
Malfunction vibration resistance is specified from 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 key model-level terms are metal lever, resin roller, 2NC contacts, slow-action mechanism, and single-conduit configuration. The source does not provide a separate load rating or contact-gap value for this row, so neither is imported from another D4N model. The common 25 mΩ contact resistance, 300 V insulation rating, speed range, and IP67 protection support the technical description while preserving the exact D4N-1B22 configuration. For another slow-action D4N roller-lever model using a resin roller, see D4N-1A20.
