The Omron D4N-4120 Limit Switch uses a roller lever with a metal lever and metal roller. Its contact form is 2NC/1NO and the operating mechanism is slow-action. The conduit specification is 1-conduit, M20. Operating speed is listed as 1 to 500 mm/s, while operation frequency is 30 operations/minute max. Electrical specifications include 25 mΩ max. contact resistance, 300 V rated insulation voltage, 50/60 Hz frequency, and 100 MΩ min. insulation resistance. These attributes define the D4N-4120 through its actuator construction, contact arrangement, action type, conduit format, operating speed, operation frequency, and the core electrical values supplied for the model. The M20 conduit specification is part of the connection format and is distinct from the metal lever and metal roller actuator description.
The D4N-4120 has IP67 protection and an operating temperature range of -30 to 70°C with no icing. Humidity is specified as 95% max. Malfunction vibration is 10 to 55 Hz at 0.75 mm single amplitude. Shock values are 1,000 m/s² min. for destruction and 300 m/s² min. for malfunction. The D4N Series is the listed product family, placing the model alongside other D4N configurations under the same series structure.
