Omron D4N-1162 Limit Switch
Omron D4N-1162 is an industrial limit switch with a horizontal one-way roller arm lever for directional position detection. The actuator responds from a defined direction, while the snap-action mechanism and 1NC/1NO contact configuration provide clear switching for control circuits. Operating speed from 1 to 500 mm/s supports varied machine movement, and the one-conduit design simplifies installation. IP67 protection and operation from -30 to 70°C support demanding factory environments. The D4N-1162 belongs to the D4N Series within the one-way roller lever limit switch range from Omron machine safety products for reliable machine position and travel detection.

The Omron D4N-1162 Limit Switch uses a horizontal one-way roller arm lever for controlled mechanical position detection. The one-way actuator is suited to applications where movement should operate the switch from a defined direction, while the snap-action mechanism provides a clear switching response. Its 1NC/1NO contact arrangement offers separate normally closed and normally open paths for control circuits. Operating speed ranges from 1 to 500 mm/s, with a maximum operating frequency of 30 operations per minute. The one-conduit design supports machine wiring, and IP67 protection helps the switch withstand dust, water, and demanding factory conditions.
Initial contact resistance is 25 mΩ maximum, while insulation resistance is 100 MΩ minimum. Rated voltage is 300 V at 50/60 Hz. The D4N-1162 operates from -30 to 70°C with humidity up to 95%, and it 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 support directional roller-arm position sensing where compact wiring, snap-action switching, and 1NC/1NO contacts are required. The one-way horizontal lever is a key application-specific feature. For another D4N Series model with a related compact limit-switch construction, see the D4N-1132 model.
