Omron D4N-1232 Limit Switch
Omron D4N-1232 combines a roller plunger with 2NC snap-action contacts for direct position and travel detection. The actuator accepts target speeds from 1 to 500 mm/s, while the switch supports up to 30 operations per minute. IP67 protection, 25 mΩ maximum contact resistance, 100 MΩ minimum insulation resistance, and a 300 V rated insulation voltage are specified. The D4N-1232 is part of the D4N Series within the 2NC roller plunger switch range from Omron switching components. Its roller plunger and 2NC snap-action configuration distinguish this model.

The Omron D4N-1232 Limit Switch uses a roller plunger with two normally closed contacts and a snap-action mechanism. Its actuator handles speeds from 1 to 500 mm/s, and the switching frequency is specified at 30 operations per minute maximum. A single-conduit configuration is provided. IP67 protection covers the switch body, while insulation resistance is 100 MΩ minimum. Contact resistance is 25 mΩ maximum and the rated insulation voltage is 300 V at 50/60 Hz. The operating range extends from -30 to 70°C with relative humidity up to 95%.
Malfunction vibration resistance is specified from 10 to 55 Hz at 0.75 mm single amplitude. The switch withstands destructive shock of at least 1,000 m/s² and malfunction shock of at least 300 m/s². Its defining combination is the roller-plunger actuator, 2NC contacts, and snap-action response. This separates it from roller-plunger D4N models that use changeover-style 1NC/1NO contacts or slow action. For that comparison, the D4N-1A32 uses a roller plunger with 1NC/1NO slow-action switching.
