Omron D4N-2232 Limit Switch
Omron D4N-2232 combines a roller plunger actuator with 2NC snap-action contacts and a G1/2 single-conduit entry. Its operating-speed specification extends from 1 to 500 mm/s, and switching frequency is limited to 30 operations per minute. IP67 protection, 25 mΩ maximum contact resistance, and 100 MΩ minimum insulation resistance are provided. The D4N-2232 belongs to the D4N Series within the 2NC roller plunger limit switch range from Omron switching products. Its G1/2 conduit configuration helps distinguish it from other D4N roller-plunger variants.

The Omron D4N-2232 Limit Switch uses a roller plunger with 2NC snap-action contacts and a G1/2 single-conduit connection. Its rolling actuator differs from the lever-style 2NC models while retaining the same basic contact form. Operating speed is specified from 1 to 500 mm/s with a maximum frequency of 30 operations per minute. The source lists IP67 protection, 100 MΩ minimum insulation resistance, 25 mΩ maximum contact resistance, and a rated insulation voltage of 300 V at 50/60 Hz. Operating temperature extends from -30 to 70°C.
Relative humidity is specified at 95% maximum. Malfunction vibration resistance covers 10 to 55 Hz with 0.75 mm single amplitude, while shock resistance is at least 1,000 m/s² for destruction and 300 m/s² for malfunction. The roller plunger and G1/2 conduit combination are the primary physical identifiers for this model. For another D4N roller-plunger switch using 2NC snap-action contacts but a source-listed generic single conduit, see the D4N-1232 model.
