Omron D4N-2A32 Limit Switch
Omron D4N-2A32 is a slow-action limit switch with a roller plunger actuator and 1NC/1NO contact form. It uses a 1-conduit, G1/2 configuration and supports operating speeds from 1 to 500 mm/s. Operation frequency is specified at 30 operations/minute maximum, while IP67 protection and 25 mΩ maximum contact resistance are listed for the switch. Rated insulation voltage is 300 V at 50/60 Hz. The D4N-2A32 belongs to the D4N Series within the roller plunger limit switch range from Omron. The roller plunger, 1NC/1NO contacts, slow-action mechanism, and G1/2 conduit specification form the core model identity and separate it from snap-action plunger versions.

The Omron D4N-2A32 Limit Switch uses a roller plunger actuator with 1NC/1NO contacts and a slow-action mechanism. The conduit specification is 1-conduit, G1/2. Operating speed is listed 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 specified. The operating temperature range is -30 to 70°C with no icing, and humidity is listed at 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 roller plunger, 1NC/1NO contact form, slow-action mechanism, and G1/2 conduit specification provide the clearest exact-model identification. These attributes also separate D4N-2A32 from the plunger and roller-lever models in the same series without inferring how the actuator should be used. Across the current D4N rows, the common 300 V insulation rating, 25 mΩ contact resistance, IP67 protection, and 1 to 500 mm/s speed range support comparison, while actuator and conduit distinguish the model. For another current D4N slow-action model with 1NC/1NO contacts, but using a plunger actuator and M20 conduit specification, see D4N-4A31.
