Omron D4N-9125 Limit Switch
Omron D4N-9125 combines a metal lever and metal roller with 1NC/1NO snap-action switching. This version uses an M12 connector rather than a conduit entry and supports actuator speeds from 1 to 500 mm/s. The source specifies IP67 protection, 25 mΩ maximum contact resistance, 100 MΩ minimum insulation resistance, and a 300 V rated insulation voltage. The D4N-9125 is part of the D4N Series within the metal roller lever switch range from Omron switching components. Its all-metal actuator distinguishes it from the resin roller-lever D4N-9120.

The Omron D4N-9125 Limit Switch uses a metal lever and metal roller with 1NC/1NO snap-action contacts. Its M12 connector provides the electrical interface, separating this configuration from similar D4N models that use G1/2 or M20 conduit entries. The actuator operates over a speed range from 1 to 500 mm/s, with a maximum switching frequency of 30 operations per minute. The source specifies 25 mΩ maximum contact resistance, 100 MΩ minimum insulation resistance, and a 300 V rated insulation voltage at 50/60 Hz. IP67 protection is also provided.
The switch operates from -30 to 70°C with relative humidity up to 95%. Malfunction vibration resistance covers 10 to 55 Hz at 0.75 mm single amplitude, while destructive and malfunction shock resistance are specified at least at 1,000 and 300 m/s² respectively. Since contact form, action type, connector, and electrical values closely match the D4N-9120, actuator construction is the clearest difference: this version uses both a metal lever and metal roller. For the corresponding resin lever and resin roller model, see the D4N-9120.
