Omron D4N-4122 Limit Switch
Omron D4N-4122 is a slow-action limit switch with a roller lever made from a metal lever and resin roller. It uses a 2NC/1NO contact form and a 1-conduit, M20 configuration. Operating speed is 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 listed. The D4N-4122 2NC/1NO Roller Lever belongs to the D4N Series within the Omron M20 Roller Lever Switch Range from Omron Switch Component Series. Insulation resistance is 100 MΩ minimum, and frequency is 50/60 Hz.

The Omron D4N-4122 Limit Switch uses a roller lever with a metal lever and resin roller, 2NC/1NO contacts, and a slow-action mechanism. The connection is specified as 1-conduit, M20. Operating speed ranges 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. IP67 protection is listed. The operating temperature range is -30 to 70°C with no icing, and humidity is 95% maximum.
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. The exact product identity is defined by the metal lever, resin roller, 2NC/1NO contact form, slow-action operation, and M20 conduit specification. The source does not provide a normal load rating, contact-gap value, lever dimensions, or durability figure, so those values are not borrowed from other D4N models. No current rating is separately listed. The common resistance, insulation, speed, frequency, temperature, vibration, and shock values provide supporting technical context without replacing the model-specific actuator and contact configuration.
