Omron D4F-102-3R Limit Switch
Omron D4F-102-3R combines a metal roller-plunger actuator with 1NC/1NO slow-action contacts. It has a 3 m cable in horizontal orientation, a 2 × 2 mm minimum contact gap, and an operating-speed range from 1 mm/s to 0.5 m/s. IP67 protection is specified. The D4F-102-3R belongs to the D4F Series within the roller plunger limit switch range from Omron. The 3 m cable is the main distinction within the D4F-102 horizontal versions, while the metal roller, 1NC/1NO contact form, slow-action mechanism, and contact gap define the core switch configuration and separate it from the 1 m horizontal version in the same model group.

The Omron D4F-102-3R Limit Switch operates from 1 mm/s to 0.5 m/s. Mechanical operation frequency is specified at 120 operations per minute and electrical operation frequency at 30 operations per minute. Because this version uses a 3 m cable, maximum contact resistance is 500 mΩ. Insulation resistance is 100 MΩ minimum, rated insulation voltage is 250 V, and frequency is 50/60 Hz. These specifications complete the electrical profile behind the metal roller plunger, 1NC/1NO slow-action contacts, horizontal orientation, 3 m cable, and 2 × 2 mm minimum contact gap.
The operating temperature range is -30 to 70°C with no icing, while humidity is 95% maximum. Malfunction vibration resistance covers 10 to 55 Hz at 0.75 mm single amplitude. Destructive shock resistance is 1,000 m/s² minimum and malfunction shock resistance is 300 m/s² minimum. IP67 protection is specified. Within the D4F-102 group, the 3 m cable and corresponding 500 mΩ contact-resistance limit are the clearest differences from the shorter version while the actuator and contact form remain unchanged. Within the D4F-102 group, the 3 m horizontal cable, 500 mΩ contact resistance, metal roller plunger, and 1NC/1NO slow-action contacts form the most specific combination for this model. For the related 1 m horizontal configuration, see D4F-102-1R.
