Omron D4N-1132 Limit Switch
Omron D4N-1132 is an industrial limit switch with a roller plunger actuator and snap-action mechanism for reliable machine position detection. The rolling actuator suits cams, slides, and moving parts that pass across the sensing point, while the 1NC/1NO contact arrangement provides separate normally closed and normally open control paths. Operating speed ranges from 1 to 500 mm/s, and the one-conduit design supports practical machine wiring. IP67 protection and operation from -30 to 70°C suit demanding factory environments. The D4N-1132 belongs to the D4N Series within the industrial roller plunger limit switch range from Omron machine safety products for dependable position and travel detection.

The Omron D4N-1132 Limit Switch uses a roller plunger actuator with a snap-action mechanism for reliable machine position detection. The rolling actuator suits cams, slides, and moving parts that pass across the sensing point, while the 1NC/1NO contact arrangement provides separate normally closed and normally open switching paths for control circuits. Operating speed ranges from 1 to 500 mm/s, and the switch supports up to 30 operations per minute. A one-conduit design supports practical machine wiring, while IP67 protection helps the switch withstand dust, water, and demanding factory conditions.
The D4N-1132 has an initial contact resistance of 25 mΩ maximum and insulation resistance of 100 MΩ minimum. Rated voltage is 300 V at 50/60 Hz. The switch operates from -30 to 70°C with humidity up to 95% and withstands destructive shock of at least 1,000 m/s² and malfunction shock of at least 300 m/s². Malfunction vibration resistance covers 10 to 55 Hz at 0.75 mm single amplitude. These characteristics suit compact roller-plunger sensing where snap-action switching and 1NC/1NO contacts are required. The roller plunger is well suited to repeated contact where a target moves across the actuator face. For another D4N Series model using directional roller-lever actuation, see the D4N-1162 model.
