Omron D4N-2225 Limit Switch
Omron D4N-2225 uses a metal lever and metal roller with 2NC snap-action contacts for roller-lever position switching. It includes a G1/2 single-conduit entry and supports actuator speeds from 1 to 500 mm/s. Contact resistance is specified at 25 mΩ maximum, with IP67 protection and 100 MΩ minimum insulation resistance. The D4N-2225 is a D4N Series model within the metal roller lever limit switch range from Omron control components. Its all-metal lever and roller arrangement is the clearest difference from the resin-actuator D4N-2220.

The Omron D4N-2225 Limit Switch uses a metal lever together with a metal roller and 2NC snap-action switching. This all-metal actuator arrangement is the primary model-specific characteristic when comparing it with other D4N roller-lever options. The G1/2 single-conduit switch supports operating speeds from 1 to 500 mm/s and a maximum operating frequency of 30 operations per minute. IP67 protection, 25 mΩ maximum contact resistance, 100 MΩ minimum insulation resistance, and 300 V rated insulation voltage are specified.
The source lists an operating range from -30 to 70°C and relative humidity up to 95%. Malfunction vibration resistance is 10 to 55 Hz at 0.75 mm single amplitude. Destructive shock resistance is at least 1,000 m/s² and malfunction shock resistance at least 300 m/s². Since the contact form and switching mechanism match the D4N-2220, actuator material becomes the clearest point of comparison. For the 2NC snap-action version using a resin lever and resin roller, see the D4N-2220 model.
