Omron D4N-2162 Limit Switch
Omron D4N-2162 is distinguished by a horizontal one-way roller arm lever combined with 1NC/1NO snap-action contacts. The one-way actuator provides a specific directional operating format, while a G1/2 single-conduit entry is provided for wiring. Operating speed extends from 1 to 500 mm/s, with IP67 protection and 25 mΩ maximum contact resistance. The D4N-2162 belongs to the D4N Series within the one-way roller arm limit switch range from Omron limit switch products. Its horizontal one-way actuator is the primary mechanical selection feature.

The Omron D4N-2162 Limit Switch is mechanically defined by a horizontal one-way roller arm lever. The actuator is paired with 1NC/1NO snap-action contacts and a G1/2 single-conduit connection. Operating speed ranges from 1 to 500 mm/s, and the switch supports up to 30 operations per minute. The source specifies 25 mΩ maximum contact resistance, 100 MΩ minimum insulation resistance, and IP67 protection. Rated insulation voltage is 300 V at 50/60 Hz, while the operating temperature range extends from -30 to 70°C.
Relative humidity is specified at 95% maximum. Vibration resistance for malfunction covers 10 to 55 Hz at 0.75 mm single amplitude. Destructive shock resistance reaches at least 1,000 m/s² and malfunction shock resistance at least 300 m/s². The horizontal one-way operating format is the principal difference from conventional roller-lever D4N models and should be the first mechanical selection criterion. For a standard metal-lever and resin-roller model using the same 1NC/1NO snap-action contact arrangement, see the D4N-2122 model.
