Omron D4F-302-1D Limit Switch
Omron D4F-302-1D combines a metal roller plunger with a 2NC/2NO contact arrangement, providing four contact paths from one slow-action actuator. This version uses vertical orientation and a 1 m cable. Operating speed ranges from 1 mm/s to 0.5 m/s, while IP67 protection, 100 MΩ minimum insulation resistance, and a minimum 2 × 2 mm contact gap are specified. The D4F-302-1D is part of the D4F Series within the 2NC/2NO roller plunger switch range from Omron switching components. Its 1 m lead is the shortest cable option in this group.

The Omron D4F-302-1D Limit Switch uses a metal roller plunger with a 2NC/2NO slow-action contact arrangement, giving the model four switching contacts rather than the two-contact configurations found in D4F-202 versions. This variant has vertical actuator orientation and a 1 m cable. Operating speed ranges from 1 mm/s to 0.5 m/s, with mechanical frequency up to 120 operations per minute and electrical frequency up to 30 operations per minute. IP67 protection, 100 MΩ minimum insulation resistance, and a 2 × 2 mm minimum contact gap are specified.
The 1 m cable corresponds to 300 mΩ maximum contact resistance. Malfunction vibration resistance is specified from 10 to 55 Hz at 0.75 mm single amplitude, with destructive shock resistance of at least 1,000 m/s² and malfunction shock resistance of at least 300 m/s². The model operates from -30 to 70°C at up to 95% relative humidity. The short cable is its clearest difference from other D4F-302 vertical variants. For the same actuator, contacts, and orientation with a 3 m lead, see the D4F-302-3D model.
