Omron D4F-202-5D Limit Switch
Omron D4F-202-5D is a slow-action D4F limit switch with a metal roller plunger, 2NC contacts, and a 5 m cable. Its vertical actuator arrangement supports direct position detection over an operating-speed range of 1 mm/s to 0.5 m/s. IP67 protection, a minimum 2 × 2 mm contact gap, and 100 MΩ minimum insulation resistance are specified. The D4F-202-5D belongs to the D4F Series within the 2NC roller plunger switch range from Omron limit switch products. Its 5 m cable and vertical orientation are the main configuration details.

The Omron D4F-202-5D Limit Switch combines a metal roller plunger with two normally closed contacts and a slow-action mechanism. The actuator is vertically oriented and connected through a 5 m cable, making cable reach and actuator direction the main physical selection points. Operating speed ranges from 1 mm/s to 0.5 m/s, with up to 120 mechanical operations and 30 electrical operations per minute. The switch provides a minimum 2 × 2 mm contact gap, IP67 protection, 100 MΩ minimum insulation resistance, and operation from -30 to 70°C with humidity up to 95%.
The 5 m cable corresponds to a maximum contact resistance of 700 mΩ in the supplied specifications. Malfunction vibration resistance is 10 to 55 Hz at 0.75 mm single amplitude, while shock resistance is listed at 1,000 m/s² minimum for destruction and 300 m/s² minimum for malfunction. Rated insulation voltage is 250 V at 50/60 Hz. This model is primarily distinguished by its vertical roller plunger, 2NC contact form, and longer cable. For the same 5 m roller-plunger and 2NC configuration with horizontal orientation, see the D4F-202-5R model.
