The Omron D4N-412G Limit Switch uses an adjustable roller lever, form lock, with a metal lever and resin roller. Its contact form is 1NC/1NO and the operation mechanism is snap-action. The connection specification is 1-conduit, M20. Operating speed is 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 values define the model through its actuator construction, contact form, action mechanism, conduit specification, operating speed, operation frequency, and electrical characteristics. The metal lever and resin roller are the stated actuator materials, while the M20 value belongs to the 1-conduit connection specification.
The D4N-412G is rated IP67 and is specified for operation from -30 to 70°C with no icing and humidity of 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-212G in the same uploaded batch lists the same actuator description, 1NC/1NO contacts, snap-action operation, 1 to 500 mm/s operating speed, and 30 operations/minute max., but its conduit specification is G1/2 rather than M20. See the D4N-212G.
