Omron D4F-302-5R Limit Switch
Omron D4F-302-5R uses the same 2NC/2NO slow-action contact arrangement and metal roller plunger as other D4F-302 models, but combines them with horizontal orientation and a 5 m cable. The switch operates from 1 mm/s to 0.5 m/s and provides IP67 protection with a minimum 2 × 2 mm contact gap. The D4F-302-5R belongs to the D4F Series within the horizontal multi-contact plunger switch range from Omron switching products. Orientation is the key distinction when comparing it with the corresponding 5D model.

The Omron D4F-302-5R Limit Switch combines a metal roller plunger, four-contact 2NC/2NO switching, and horizontal actuator orientation. Its 5 m cable provides extended connection distance, while the slow-action mechanism operates from 1 mm/s to 0.5 m/s. The switch supports 120 mechanical operations per minute and 30 electrical operations per minute. IP67 protection, 100 MΩ minimum insulation resistance, and a minimum contact gap of 2 × 2 mm are part of the specified configuration.
With the 5 m cable, contact resistance is 700 mΩ maximum. Operating temperature is -30 to 70°C with relative humidity up to 95%. Vibration resistance for malfunction is specified at 10 to 55 Hz with 0.75 mm single amplitude. Shock resistance reaches at least 1,000 m/s² for destruction and 300 m/s² for malfunction. Because this model otherwise matches the 5D version closely, horizontal orientation is the primary model-selection distinction. For the corresponding vertically oriented configuration, see the D4F-302-5D model.
