Omron D4F-302-5D Limit Switch
Omron D4F-302-5D provides 2NC/2NO slow-action switching through a metal roller plunger and uses a 5 m cable for extended wiring distance. The actuator is arranged vertically and works across a 1 mm/s to 0.5 m/s operating-speed range. IP67 protection, 100 MΩ minimum insulation resistance, and a minimum 2 × 2 mm contact gap are listed. The D4F-302-5D sits in the D4F Series within the 5 m roller plunger limit switch range from Omron control products. Its long cable and vertical orientation distinguish it from other D4F-302 configurations.

The Omron D4F-302-5D Limit Switch is the long-cable vertical version of the 2NC/2NO roller-plunger configuration. A metal roller forms the actuator contact point, while the 5 m cable provides the maximum wiring reach among the 1D, 3D, and 5D models in this group. Slow-action switching supports operating speeds from 1 mm/s to 0.5 m/s. The source specifies a 2 × 2 mm minimum contact gap, IP67 protection, 100 MΩ minimum insulation resistance, and up to 120 mechanical or 30 electrical operations per minute.
Contact resistance is listed at 700 mΩ maximum for the 5 m cable. Environmental specifications include -30 to 70°C operation and humidity up to 95%. Malfunction vibration resistance covers 10 to 55 Hz at 0.75 mm single amplitude, while shock resistance is at least 1,000 m/s² for destruction and 300 m/s² for malfunction. This version is differentiated by cable reach and vertical orientation. For the same 5 m cable, metal roller plunger, and 2NC/2NO contacts with horizontal orientation, see the D4F-302-5R model.
